Prusa i3 - IKEA Lack enclosure - filament slot

thingiverse

I have constructed the Prusa i3 MK3 enclosure using an Ikea Lack table, and it's a fantastic result. However, I was not satisfied with the filament feeder tubes, particularly when the extruder is near its highest position. Here's my approach to resolving this issue - a slot that matches the length of the x-axis movement. This makes it much simpler for the extruder to draw the filament from the spool at any point on the x-axis, as there is very minimal friction in the slot.
