Ikea Lack Table Filament Guide

Build this as a filament guide through a 1/4" hole I drilled in my Ikea Lack Table for filament.
You can view and/or download the [source file from here](http://a360.co/2zEbwv0)
The exterior diameter is 4.5mm while the interior is 3mm (good for 1.75mm filament, which is my use case)


I plan to make a better version of this soon, but this is currently what is fitted in my setup until after the holidays.

EDIT: This has been in my setup for almost two years and I haven't had to replace it once.
