Fairy Ring

Vibe CAD for real things / talk, point, and it gets made

One hundred things made in Fairy Ring, knolled: tables, stools, benches, cases, finger-jointed boxes and trays, mycelium trays, and concrete, clay, wax and glow vessels

Put on a Quest and say what's in your head. “Taper the legs this much.” “Spin it like this.” The model changes live, full size in the room, while your hands show the sizes. When it's right, Fairy Ring makes it: cut files with the joints already solved, printable molds, a build plan with a cut list, a parts cart, and a job for whichever dancer in the ring can do it. Nothing is ever bought without you.

  1. Say it, show it. Hold the pad key and talk. Hands fill in the numbers: “this wide” reads the gap between your palms, and the edit commits when your hand holds still or you say “there.”
  2. Fairy Ring edits. Simple commands skip the AI and land in a tenth of a second. Anything else goes to Claude, which calls the same CAD tools. Every edit is a saved version, so undo is free.
  3. Make it. Cut files with box joints and kerf, molds sized to the printer bed, a build plan you walk with “next step,” carts grouped by vendor, and jobs routed to the machines below.

  1. The one you wear. Passthrough puts the model in the room at true size. Hand tracking turns gestures into dimensions, with a ghost preview until you commit.
  2. The one on the rail. Mounted upside down with the strap off, it becomes a room camera. With two webcams it feeds the camera wall, so Fairy Ring can see the bench, the boards and the molds.
  3. Anchor tags. Six-inch AprilTag cards on the bench, the machines and every rough-milled blank tie both headsets to the real room, so a scanned board and a model line up to the millimetre.

One piece, start to finish

A walnut stool / from a sentence to a finished piece

  1. Say it. “A three-legged stool, 18 inches tall, walnut seat, splayed legs.” Fairy Ring builds it live in the room.
  2. Show it. Hands set the seat width and the splay. “Thinner.” “There.” Every change is saved.
  3. See it. Walk around it at full size. Sit on a real chair beside it to check the height.
  4. Make it. Fairy Ring writes the cut list, the leg tenons for Mortisha, a seat veneer pattern for Drag Queen, layout lines for Lady Liner, and a cart for the walnut.
  5. Build it. Mortisha cuts the joints. Drag Queen and Flex Appeal lay the veneer. Honey Glaze glues and oils it. “Next step” walks you through the rest.
  6. Keep it. Vogue scans the finished stool for the site, and every offcut is logged for the next piece.

Hands

Six gestures / show the size instead of saying it

Span gestureSpantwo hands

“Make it this wide.” Hold both hands up. The gap between your two index fingertips becomes the size, taken literally. Turn your hands upright for “this tall.”

Pinch gesturePinchone hand

“Taper the legs this much.” Open your thumb and index finger. Closed is the smallest the setting goes and 4 3/4 in apart is the largest.

Drag gestureDragone finger

“Move it this way.” Point and slide your index finger. The part follows the fingertip.

Twist gestureTwistone wrist

“Spin it like this.” Turn your wrist. Turning it flat spins the model; rolling it sets an angle such as leg splay.

Hold still gestureHold stillcommit

A ghost of the change follows your hand live. Hold still for under a second and it commits.

Say “there” gestureSay “there”commit

Or say “there” or “done” to commit right away. Say “undo” to take it back.

“Make it 20 percent taller.”Scales one direction.
“This wide.”Reads the gap between your hands.
“Taper the legs to an inch at the foot.”Named part, named size.
“Round the edges a quarter inch.”Fillets every outside edge.
“Box joints on all four corners.”Solves the joints for the sheet and the kerf.
“Show me it in cherry.”Swaps the material look.
“Undo.” / “Go back three.”Every edit is a version.
“Make the mother mold.”Writes a Mother grow mold for the shape.
“Print it in wax.”Sends it to Queen Bee with the casting blend.
“What does it cost?”Parts and material total, nothing bought.
“Next step.”Walks the build plan.
“Send it to the ring.”Splits the job across the dancers.

The rig

The PC on its own isolated chassis, two new monitors (a 34 in ultrawide and a 15.6 in camera screen), a battery and the cameras in one rolling flight case

The rig open: ultrawide in the lid, camera-wall screen on the right, the Quest and webcams on the rail, the Pocket 3 on its arm

One white box on four casters. Closed, it straps into the back of a Jeep. Open, the lid swings up with the ultrawide already in it, the camera-wall screen clips on the right, the camera Quest 3S and webcams sit on the rail across the top, and the macro pads drop into pockets at desk height. An Osmo Pocket 3 on a magic arm films your hands and face from the right, and the DJI Mic 2 is the speech mic; both charge in a deck dock while the case is closed. The battery is a UPS: unplug it, roll it to another room, and the tower never shuts down.

How it works

Closed: a flight case / open: a workstation

Closed and latched
Inside: PC chassis right, battery bottom left
  1. Closed. Four draw latches, gasketed seams and down-facing hoods on every opening. Drip-resistant, not waterproof. Recessed D-rings strap it to the Jeep's tie-downs.
  2. Open. The lid rises on two gas struts to 100°. The camera-wall screen drops into two receivers, the Quest and webcams screw onto the lid rail, the Pocket 3's arm screws into a socket at the front-right corner, the pads sit in the deck.
  3. Rolling. The Anker SOLIX switches over in under 10 ms. A travel router under a rear hood keeps the same network in every room; home Wi-Fi, a phone or Starlink just feed it.

Print prices are rough per-part figures; Xometry will quote higher than JLC3DP. The sign shop needs a quote.

Build steps and numbers
  1. Measure first: the macro pads, the Quest visor height and the PC parts. Every size is a parameter at the top of rig.py.
  2. Have a sign shop route the ACM panels; cut the plywood parts from printouts.
  3. Assemble the 2020 frame with cast corner brackets. Body first, then lid.
  4. Bolt the casters through the floor, then the 0.12 in aluminium PC chassis on its rubber isolators.
  5. Skin the body with M5 button heads into drop-in T-nuts; fit the EPDM gasket.
  6. Mount fans, filters, hoods and the powerCON inlet; run the fans off a motherboard header.
  7. Hang the lid on the piano hinge with gas struts and the locking stay; mount the ultrawide.
  8. Laser cut the acrylic; glue the Quest cradle with Weld-On 4.
  9. Battery in its bay. Move the PC parts out of the NZXT case onto the chassis: board plate, GPU saddle, radiator and PSU clamps.
  10. Pull the plug with the PC under load and check it rides through.

Waste less

Six rules the whole system is built around

  1. Make it once. Seeing a piece full size in the room before cutting anything catches the wrong size, the wrong proportion and the wrong wood. The best scrap is the one never made.
  2. Cut what you need. Fairy Ring nests parts on the sheet and writes the cut list from the model, so boards are bought to length and offcuts are tracked.
  3. Grow, don't buy foam. Packaging, inserts and insulating forms come from Mother instead of polystyrene.
  4. Loop the plastic. Failed prints and trimmed vacuum-formed sheet go to Lazarella. Brims and wax scrap go back to Queen Bee.
  5. Wash the formwork. Mud Diva's clay molds are slaked and reused, so the only waste from a concrete pour is the water.
  6. Small machines, small power. Every dancer is a desktop machine. The whole ring at once draws less than one shop dust collector.

The research

Studies behind the materials

The numbers behind those rules, from published studies.

8%of global CO₂

Cement is the binder in concrete, and making it releases about 8% of the world's CO₂. That's why Mud Diva prints thin, only where the part needs it, into clay formwork that is washed off and reused.
Chatham House, Making Concrete Change (2018) →

Grownnot made

Mycelium composites are fungal root grown through farm waste like hemp hurd. Reviews find them low-energy to make, light, insulating, and compostable at the end of their life, with weak points too: they soak up water and aren't structural. Mother uses them for shapes, packaging and insulating forms, sealed when they'll see water.
Jones et al., Materials & Design (2020), engineered mycelium composites review →

How you grow itchanges what you get

How the mycelium is fed, packed and pressed changes how strong, dense and water resistant it ends up. That's why Mother packs every mold by weight, and why the drying is tested.
Appels et al., Materials & Design (2019) →

3 to 80%+less energy

Turning waste plastic into filament at home, rather than making new filament in a factory, saved from 3% to over 80% of the energy, depending on where you live and how the power is made.
Kreiger, Mulder, Glover & Pearce, Journal of Cleaner Production (2014) →

½the energy

Pairing a recyclebot with a 3D printer in the same shop, so failed prints become new filament, cut the embodied energy of the parts in half and their cost to pennies. Lazarella is that loop.
Zhong & Pearce, Resources, Conservation & Recycling (2018) →

~9%of plastic is recycled

Only about 9% of the world's plastic waste is recycled. The rest is burned, landfilled or leaks into the environment. Keeping shop plastic in a loop is a small piece of that.
OECD, Global Plastics Outlook (2022) →

Thingoes further

Simple arithmetic: a 1 in board resawn as solid stock gives two faces, but sliced into veneer about 0.024 in thick it gives dozens of leaves, each one a full face. Figured and rare woods go furthest that way, which is why Drag Queen works in veneer.

Poundsnot tons

A hive makes only a pound or two of wax a year, and bees eat a lot of honey to make it. Queen Bee's wax is precious, so every brim and failed print gets remelted, and casting work leans on the 80 / 20 blend.
FAO, Value-added products from beekeeping →

Questions

The ones people ask first

Do I need to know CAD?

No. You talk and point. Fairy Ring turns that into a real CAD model with exact sizes. If you do know CAD, the model exports as STEP, STL and DXF.

Does it buy things on its own?

Never. It builds the cart and the total, and you decide.

What does it run on?

A gaming PC in the rig, two Meta Quest 3S headsets, and Claude for anything that isn't a simple command.

How exact is it?

The model is exact. Hand gestures land within a few millimetres, and you can always say the number instead.

Can the machines run while I'm away?

Some can. Handmaiden swaps plates and loads sheets so printers and the laser can work through a queue. Nothing with a flame or a spindle runs alone.

Is it safe?

Each machine has its own safety notes in its recipes. The rules everywhere: a fire extinguisher by the laser, gloves for cement and hot sheet, a mask for dust and grows, and never leave heat or a spindle running alone.

Is any of it built yet?

The software runs. The machines are designed with full parts lists and files, and they're being built now.
