I designed it to be printed at 300% (x/y) and 600% (z) scale, but fusion360 kept crashing when I tried to up-scale the model. Those are the recommended size settings of this model. I printed in white matte PLA at standard settings 0.2mm layers with 10% lightning infill. There is a slot designed into the back. No supports required.
The author marked this model as their own original creation.
