1.75/3mm filament guide

An insertable filament guide for guiding filament through a IKEA LACK tabletop into an enclosed buildchamber of sorts.

I uploaded various versions, a circular/hexagonal top, 1.75/3mm versions, and filleted/nonfilleted. For people that wish to remix this thing i also included the master .123d file containing every component i used.

Ideas for improvement are:
Adding 3-4 fins between the base and tube to prevent rotation (no glue needed!).
Modifying such that the base and stem are seperate
