OEM Cup-Holder Reinforcement

Pair of reinforcement brackets for fitting a universal T2/T3 cup holder in a BMW E39. The creator reports that it supports McDonald’s drink sizes without smaller cups tipping and accepts PET bottles up to 0.5 litres. Print two brackets in ABS or PETG; PLA can deform in summer cabin heat. After printing, tap M4 threads in the holes, shorten the screws so they sit flush without protruding, and attach the brackets to the cup holder. These replace the unstable sheet-metal clips supplied with the universal holder. Verify dimensions, fastening, and unobstructed operation before regular use.
