This is a small form strong guitar mount bracket designed for tighter spaces. It uses two 3-5 mm diameter screws with 90mm from the axis' (i dont know what axis is plural). I printed this model back part of the bracket facing down using zero support and PLA. I used 50% infill density which spent around 40 grams, although you can use 100% density @ around 64 grams.

NOTE: The Von Mises stress test was done under the conditions of 100% infill density
