Filament Guide Tube Mount for 2020 Extrusions

thingiverse

This is a versatile filament guide tube mount designed specifically for attaching to 2020 extrusion profile. The base, tube mount, and retainer work seamlessly together using an M3 bolt threaded directly into the plastic. The base securely attaches to the aluminum profile via T-nuts, while the tube is firmly held in place by zip ties at the pockets provided. The purpose of a filament guide tube is to prevent the extruder from being lifted as it feeds filament off the spool, resulting in improved print quality. During my test prints, the PTFE 4mm OD bowden tube fit snugly, offering a strong friction fit. However, some effort may be required to clean out the hole depending on how your printer produces that feature. The larger version with a 7mm bore fits 1/4" OD PTFE tubing perfectly. Future versions of this mount are planned to incorporate a mechanical end-stop for a filament run-out sensor. ============================================================== If you find this item helpful, consider supporting me at: http://paypal.me/MarkGarety.
