2-parts motor mount, designed to break on impact.
Print a few spare motor plates, this is what breaks on crashes, much easier to replace than undoing the glue and cutting the fuselage to replace the acrylic plate.
Use high infill.
ABS or PETG prefered, or if you can print it, nylon is a good choice too.
Avoid PLA, as there are threaded holes that will strip out.
