Filament guide for PTFE liner for Mendelmax 2

youmagine

This filament guide requires a PTFE liner insert that needs to be fitted inside, possibly requiring drilling out to accommodate the PTFE liner properly. By installing it directly into the extruder, you'll be able to print more flexible filaments with ease. I advise printing in ABS if your printer is enclosed for optimal results. When it comes to creating supports, I found S3D to be an excellent tool.
