Siemens integrated microwave button interconnector

After many years of use, most used buttons (On/Off, Door Open, Start/Stop) on my Siemens integrated microwave become loose and fell inside. Instead of throwing this faithful device I found that it's possible to fix it. You need to disassemble display module, take PCB out to get to the buttons, and place this interconnector between each two affected buttons. I need to print 3 of those. To hold them in place, you need to put a piece (a square about 10x10mm) of foam sticky tape about 2mm thick onto the wide part of this 3D printed part AFTER you inserted it between buttons. When all done, reassemble it back again, and buttons will stay in place without falling inside.
