This is a lot to unpack so it bears some explanation. Like most K1 Max owners, I didn't like the Bowden tube constantly rubbing against the glass lid so I printed this riser:

and this corner piece with filament hole:

All credit goes to the original designers - thank you for making great files.

I remixed the front and back panels to be vented, so problem solved. (They also make a great light show in a dark room!)

Then I tackled the poor design of the Bowden tube placement. The Bowden tube passes through the guide and then the cap locks onto the back. *I decided to bypass the filament sensor. I print a lot so I'm always aware of the amount of filament I need for each print - so I stuck a piece of filament in the sensor and bypassed it altogether. I removed two of the three Bowden tube clips that came with the printer and left one as seen in the photo. The small Bowden tube channel is glued in to place - I use superglue activator and high-viscosity superglue. No problems since. Rock on.
