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.
