modified original model to allow for the full screen of the OLED switch to be visible, and to allow the controller to snap in more easily.
the rubber bands or hair tie are optional, and not needed if you have your filament dialed in perfectly for the K value and flow.
HIGHLY suggest printing in ASA or ABS for durability, but i have given out plenty made in just PLA. i do not recommend PETG as this will just snap after a few uses.
if using just the STL, make sure to use supports for the little fins, and maybe for the charger hole.
