Remix K1 riser with hinges for lid, added vents (open/close), PTFE tube exit out right rear to the side.

Needed hardware: 4 - 50mm m3 Round Hex Head Screws You will have to change the path of the print head cable to accommodate the rear vent. See the photos for what I did for this change. Print in ABS or ASA since the top gets the most heat. My chamber reached 45C while printing ASA bed temp of 90C with all vents open (not removed). Magnets for the vents are 5x2mm Neodymium Round Magnets. I got mine from Amazon . You will need 28 of these magnets, and the Amazon link is a quantity of 100 for $10. The vent magnets are unnecessary, but ensure they don't vibrate to an unwanted position. The magnets can easily be pressed into the vent parts. Make sure magnets attract each other for opposing vent parts; the same poles facing each other will not provide the desired holding effect.
