ctc / replicator 1 filament guide

no drilling is needed to mount this guide on the back of ctc.
Designed with FreeCAD.

V19 : diameter for cable expanded so that additional cable (for extra fan) can be feed through. version with thread added.

if you want to use the threaded version, try test-thread first. i had to print the part with 0.1mm for the last mm. slight rework might be needed to make the threads working. If in doubt, use the version wo thread.
