Clip-on filament guide for Makerbot 2

thingiverse

This thing was created with Tinkercad and can be edited online at https://www.tinkercad.com/things/42gi4KWUaYq. This clip-on filament tube guide is specifically designed for the Makerbot Replicator 2, but it may also fit other printers. I used it to relocate my filament spool to the front of the printer by using a bolt-on spool holder from http://www.thingiverse.com/thing:1602053 as the mounting point at the front of the printer. This setup greatly simplifies changing filament and spools, especially if your printer is situated against a wall. Note that the filament tube should be fitted lightly snug but not too tightly. It should have some room to twist slightly. If the top hole is too tight, you can use a drill bit to gently round it out a bit.
