Requirements:

• I recommend non-porous filament such as PETG. I used this one https://amzn.to/3QbSDX1.

Tips:

• You can print with 3 walls and no sparse infill to reduce filament cost if desired.
• Due to the overhang and small parts, print slow at 50-100%.
• Dry the filament first. PETG recommendation is 65C for 6hrs.

Straw recommendation:
