Linbell Battery-less doorbell Euro mounting plate

thingiverse

I purchased this bell for my mom's apartment. They have a concrete wall that is difficult to attach something to and an aluminum door, making the switch useless. Since the only solutions offered were to stick it on or drill screws through a double-sided sticker, I designed a mounting plate to replace the old doorbell switch. This is a mounting solution for the European standard. You need 2 "wedges" for any of the plates. I recommend using metal ones from another switch or the old doorbell switch. Alternatively, you can use the provided 3D printable ones ("wedges.stl" or "wedges2.stl"), though their quality is uncertain. To secure the plate to the wall, choose one of four options: flush with the wall, square plates ("Internal-Square-plate.stl"); flush with the wall, circular plates ("Internal-Circle-plate.stl"); or not flush with the wall, square plates ("External-Square-plate.stl"). If you need to edit the design, use the Sketchup file "bell plate.skp".
