These are parts for a custom delta printer with a 310mm build plate. The design emphasizes easy/fast assembly, composability in farms, and support for precise manual calibration. It includes a novel, very simple, and low cost heated chamber design that allows for very high chamber temperatures (50C+) while keeping all electronics, steppers, and (crucially) belts thermally insulated. It's good for high-throughput printing with ABS and ASA.
Full documentation of the build is not yet available.

BOM:
- 5-3-320MM Carbon fiber rods.
- OMG Extruder. The best extruder I've used by far.
- Piezo Probe. 100% essential. See the piezo mount model. There is support for a bltouch as well but don't use it.
- 6mm Belts.
- Nema 17 steppers. 2A minimum I would say.
- POM Pully wheel set.
- Stepper Pully Teeth
- Bearing Pully Teeth
- SKR Mini E Board. Running Klipper of course.
- 400W PSU. Go higher if you want to run a chamber heater from the PSU. With a good mosfet you could theoretically control chamber temps using the third fan port on the SKR.
Gantry Plates. Carriage parts attach to these and I also use them to pinch the build plate in place, so I use 6 in total. - Bowden Tube
- 400mm Aluminum Extrusions
- 1200mm Aluminum Extrusion
- 310mm hot bed. Overpriced. Maybe there's something cheaper on the market now.
- Glass build plate
- Aluminum volcano heat block
- Heatbreak
- Silicone Block Cover
- Thermistors. Do not buy the cheaper ones. These last.
- Thermal Tape. For thermal transfer to build plate and to pinch the build plate in place.
- M4 x 12mm Locking washers. All the main supports use 12mm washers.
- M4 x 8mm bolts. Vast majority of required bolts.
- M4 T Nuts.
- 50mm M3 rods. Thread these through the extrude rassembly using your drill.
- M3 bits. Mostly for Extruder assembly and rods.
- 24V blower fan
- Part cooling fan.
- Tension Springs. Helps a lot to tension the carbon fiber rod pairs.
- Endstops
- M5 Bolts. You'll need just three M5 bolts and locking nuts for the top pully wheels. Might be able to get away with M4s.
- Radiant Barrier Insulation. For under build plate and side panels.
- Magents. To hold the side heat shields in place.
