A remixed version of user @ianfolds double hook designed to work with the 3m command strip backing for direct attachment. Prints with PLA and no supports. gcode file from prusaslicer for a prusa mini+ and PLA included.
The author remixed this model.
The original is designed to work with the back provided by 3M, but my back broke and I didn't have another handy, but had plenty of command strips. Filled in the back and directly attached it. Printed in PLA without supports. PLA is known not to be the best with staying stuck to command strips but this was an easy replacement.
