MBOT Plywood Printer Filament Guide
thingiverse
The MBOT DIY Plywood 3D Printer comes with a spool holder, but it lacks a filament guide that prevents the filament from dragging and pulling on the print head. This part will attach to the back of the printer using two existing holes. Attach a 4-inch outer diameter / 2-inch inner diameter PTFE tube from the top of this guide to the extruder (it needs to be long enough to reach the front right corner of the printer). (updated): I added the extruder guide tube holder modified from https://www.thingiverse.com/thing:2650720 for the 4mm OD tube. (1) Printed Part (2) M3x10mm screws (if you are screwing through the wood tapping into the part) or 12mm screws if you are going to use nuts. (26 inches) PTFE tube (I like slick Capricorn tubes: https://www.captubes.com/shop/ or https://www.filastruder.com/products/capricorn-ptfe-tubing )
