Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4049747. I can't test these parts, unfortunately I don't have a Prusa. Maybe you do? They look like they should fit and I'm usually pretty good about these sorts of things. If they don't :shrugs: Print these parts in their current orientation. Use 0.25mm layer height to take advantage of the incremental bridging. Do not use supports, none of the overhangs exceed 57 degrees and the longest bridge is 10mm. Check out the following listing for a PINDA bracket and a air-pump duct: https://www.thingiverse.com/thing:4009736 Requires counter-sunk and button head M3 bolts and #4 screws.
