PetSafe Dog Flap replacement frame, medium

A three-part model that can be glued together to make a replacement frame for a Staywell® Original ("700 Series") 2-Way Pet Door ("PetSafe") medium-sized dog flap. For sizing, the hole in door of the Medium flap is nominally 281 mm × 237 mm. We have an enthusiastic dog who likes to charge through the flap at very high speed, and she has broken the frame. Unfortunately this is not easily found as a spare part. I designed this replacement to be printable on Bambu A1 and larger printers, and to be stronger than the original design. The frame is thicker where it is highly stressed, and there is a projection near the hinge to stop the frame opening so far that it stresses the necessarily-thinner part next to the hinge. I hope people find this useful! Boost MeIf you like this model, please consider boosting it. Thank you!
