Lack Enclosure Filament Slot Guide

I added a cement paver to the inside of my Ikea Lack enclosure but it made my printer come very close to the top. This would have caused some filament issues for tall prints and would have easily snapped some filament. I used the existing holes from the original lack enclosure and cut out all the space between them making a slot that is 275mm by 10mm. Just used a utility knife to make the cut.
