E-drum pedal "adapter"

thingiverse

This is a device to turn one of those small and uncomfortable footswitches that come with many edrum kits into a more substantial full size pedal. It uses 22mm outer/ 8mm inner / 7mm wide bearings for the axle. Might need to do some sanding to get them in there, it's pretty tight. And some rubber bands pulling both up and down on it, to give it some stability and potentially adjust the force needed to press it down. The kitchen sponge is there to fill the gap and make the press down softer and more even. I designed the hooks on the moving bit you press on way too small for wrapping the rubber bands around, so I made another bit to put over it and that can be glued on or it might just stick on with regular friction. That's why it's separate, but it also prints easier I think, so I didn't bother changing it. The rubber bands pulling it down will probably snap if you just put it on the floor and stomp on it. I'm going to add non-slip rubber pads under it, so there will be a slight gap that's going to create enough space for the rubber bands to not get squished against the sharpish bottom edge too much.
