The file 'Dolphin Rear Motor Mounting Plate XL (with 34mm Center Screws) 3D Printer Model' is (stl) file type, size is 4.6MB.
The original plywood motor mounting plate on the dolphin is known to be held onto the foam with very little glue.
Many people have designed custom 3D printed mounts, but unless you really glue them, very well, into place they can get easily yanked out, by torque and other reasons.
WARNING: This design requires the removal of the original plywood plate AND for you to remove some of the foam, and that area is level with where it was (either with a scalpel, craft knife or any other method you see fit).
TIP: Do NOT use E6000, or any other flexible adhesive, to fix this into place. The idea of this design is for it to be permanent, so I advise you use 5 minute epoxy resin or similar, and be thorough.
