Preparation#

Steps to complete before assembly.

Printing the Parts#

These settings might differ a little bit, depending on your printer. The parts are designed to be printed without supports, but some printers might require them for certain parts.

  • Recommended material: PLA, PETG, or ABS (funnel should be food-safe)
  • Layer height: 0.2 mm
  • Infill: 10-20 %
  • Supports: where needed

Post-Processing#

Remove supports and clean up the parts as needed. Prepare boards, electronics, and fasteners for assembly. Pre-solder connections where possible to save time during assembly.

Pre-Assembly Checks#

  • All parts printed and cleaned
  • Electronics tested
  • Fasteners and tools ready
  • Measure converter output voltage to ensure it's set to 5 V before connecting to the Pi

Step A - Heat-Set Inserts#

First, heat-set the threaded inserts (using a soldering iron) into the printed parts that require them. Here is an overview of which insert goes where:

  • Lid Tower: two M3 on the pads
  • Tower Bottom: two M3 on the top connecting point, one M5 on the bottom
  • Tower Middle (or ring LED): three M4 on the top connecting point
  • Tower Top: eight M2.5 on the electric mounting points
