IKEA Lack filament passthrough tube

thingiverse

I built this guide to help move filament through an IKEA Lack table, as I disliked other designs I was finding which needed either making a slot with a dremel, or were very small internal diameter. My design demands drilling a 10mm hole and that's it, giving plenty of room internally so the filament doesn't rub against the sides all the way through. I've been using mine for two weeks now with no problems at all with snagging or friction. There is no visible wear on the passthrough tube itself either.
