This design is what I ride instead of the typical onewheel footpad that uses a force sensing membrane. Instead this design uses two small IP67 switches. The button is held in place above the switch by the seal, which is 1/32" EPDM (not Buna-n like the picture describes). All the pieces are held together with #4-40 x ¼"L, Flat head, philips screws. For extra hold you can add a dap of super glue to the screw.
Some correction may need to be done to get the button at just the right height so that it easily activates the switch without keeping it activated. Increasing and decreasing the height of the base is an easy way to do this. You could also add a shim under the button. I printed this with 0.2mm print height, PETG, solid.
For waterproofing I suggest potting the base with epoxy since the terminals of the switch are not IP67 rated. Only do this once you have determined that the button has good action.
The button and top flange file ending with “blank” is intended for you to use with you own footpad design so you can shape the top as you see fit.
The seal file is a template for you to use to cut out the EPDM seal.
