Remixed with bottom chamfers for better bed adhesion. No supports needed
Fits new AMS ribs. Use a rubber band to hold the sides together
Original model by @muddtt had fillets, which was a pain to print with ABS and other materials susceptible to warping (causes lifts from bed at edges). This one has chamfers at a 45 degree angle, both inside and outside. In addition, I've rotated the lid so it prints flat.
The author remixed this model.
