IKEA Lack table filament bulkhead

Very simple bulkhead (is that a correct word?) for IKEA Lack table. Fits 8mm hole. Allows you to install PTFE tube from one side. To secure the other side of the tube, just slide the lock into the slots

[Pyrec007](https://www.thingiverse.com/Pyrce007/about) made a great [remix](https://www.thingiverse.com/thing:2627700) that allows you to use M6 hose connector. Check it out if you intend to use PTFE tubing.
