Shimano Di2-Button

I saw Shane Miller (GPlama) video about these hack to make the use easier of Shimano hidden button.I look for a STL file and found on Thingeverse a file that works well for me. I just had to make the hole slightly bigger, probably due to my printer.I just use PLA for this and my guess is that they will wokr fine even under warm summer days. But you are welcome to use other material as you wish.After print I put the side that was on the build plate upwards on the shifter.Works well on my Dura Ace R9200 All credits go to Mr. Jan Müller aka JanM2000 on Thingiverse.https://www.thingiverse.com/thing:7119429
