What this project aims to solve:
1) The Lid of the Creality K1 Max 3D Printer sits a bit too low. The extruder filament feed constantly rubs on the glass during prints. Some people report getting a filament feed error due to the tight angle the filament has to enter the extruder due to the lid pushing down on it.
2) The lid needs to be removed for printing with PLA as to ensure the enclosure temperature is not too hot. The rising hot air cannot escape.
3) Keeping my cat out of the printer. It is a lovely box to sleep it.

Solution:
1) This 3D printed vented extension raises the lid by 45mm.
2) The side and rear panels are vented to allow heat to escape.
3) Having the lid now permanently in place, my cat can no longer sleep in the printer.

Notes:
1) Each of the walls can be printed standing on their side, diagonally across the plate of the K1 Max. You can only print one at a time, unless you try to get fancy stacking.
2) If you want to just print the vented walls on all four sides (and not have the front wall with the text) then you can do so.
3) The reason for the text/logo was just to try something in the 3D modeling tool I was using (OnShape).
4) This is my first ever 3d modeling, so be kind :)
