One of the biggest issues I faced with my Austin Mini is not the exploding heater valve, nor the ignition coil falling off, nor the blown out head gasket, but the lack of a decent cup holder. These kind of major issues can be solved by 3D printing. Which I did 😀
The cup holder can be placed without any screws into the ashtray space (some force required). This is still a work in progress because some areas are a little too thin and the glass transition temperature (the temperature at which the material goes into a rubbery state) of PLA is 60 to 65°C according to Wikipedia. This means that the holder will not be able hold my beverage on a hot summer day…
I still have to test this design by putting two full cans of soda into the holder and going for a ride on a bumpy road for a while. Eventually this design will be a little tougher and made out of ABS before the next summer!
P.S. Here is a photo of the holder actually holding drinks
