This is a wallmount for the charger that came with my 40V greenworks lawnmower. The charger is a model 29482. Mounting this charger can be a little tricky, as one mounting hole is facing one way and the other is facing another. You have to slot down into one of the mounting holes and then rotate into the other.
Supports shouldn't be necessary with most filaments, even if your slicer says they are.
I included a model you can use to test fit the mounting holes, in case you aren't sure about your printer's accuracy.
