Shimano Di2 Grommet SM-GM02

thingiverse

This is a replacement for the SM-GM02 di2 frame grommet. I have not actually had a chance to test this one out yet and just tried to replicate the Shimano taking measurements so let me know if it needs any tweaks. This will definitely be best to be printed in a flexible filament like TPU or with a flexible resin. There are a lot of thin areas so a small nozzle size, low speeds and plenty of cooling time will probably help get a good print. Also experiment with the angle you print it if having a hard time. I did NOT model in the cut to allow the wire to pass through. It will be easier to just print it all solid and then add that cut with a razor blade once its finished printing.
