3D Printing

Estimated time: ~34 hours

We provide ready-to-print STL files for the 3D-printed parts below. These can be printed with generic PLA filament on consumer-grade FDM printers. We tested on a Bambu Lab P1S printer. For all components, we just load into bambuslicer, auto-rotate and auto-arrange, enable any recommended supports, and print.

Parts

Note: Make sure to enable supports where specified!

Printing Instructions

Assuming you already have access to a 3D printer3, follow these steps to print all the parts above.

1. Setup Printer

  1. Calibrate the printer and level beds according to printer-specific instructions
  2. Clean the print bed
  3. Load-in filament

2. Print the Parts

  1. Upload STL file to printing/slicing software. Auto-rotate and auto-arrange.
  2. Enable supports if specified and slice. We tested with the following settings:
    • Infill Density: 15%
    • Layer Height: 0.2 mm
    • Printing Speed: 150 mm/s
  3. If needed, upload G-code (slice file) to printer and print

3. Take Down

  1. Remove printed part(s) from printer
  2. Clean print bed if needed
  3. Remove any supports from printed parts
