NOTE - your build area will be reduced by 8mm, so you have to adjust printer.cfg accordingly

position_endstop: -1.5

position_max:242

mesh_min:24,15

materials - any heat resistant will do, composites proffered due to less warping.

fix the front and back covers with rubber rings on the hooks, the front part wont fall on the buildplate in a case of failed print

added a couple of fillets
