PTFE filament guide for 2020 extrusion

A simple part to clamp the end of a Bowden tube to your printer's frame. You'll need a segment of PTFE tubing and a compatible M6 coupler. (Most commonly a 4mm OD/2mm ID tube with a PC4-M6 coupler.) You'll also need 2x M5x8 socket bolts with M5 T-nuts (or similar).

Recommended Print Settings

• 0.4mm nozzle
• 0.2mm layer height
• 10% infill
• No supports
• Print as oriented

Original description

This filament guide tightly constrains the filament using a Bowden tube.

Compared to other filament guides with a wider space, this design further prevents the filament from curling around, which is especially likely when your spool is almost finished.

• Narrowed to 10mm and shortened to 60mm
• Rearranged bolt slots for compatibility with regular frame extrusion (still compatible with SV06 frame, but without the top-mounted spool holder)
