Shimano shifter cover

thingiverse

I bought a Shimano Deore shifter (SL-M591) with an indicator display which I don't want. I still need something to prevent dirt & water ingress, so I made this. I removed the display, & while it has the tabs for holding the spare cover, it wasn't included for some reason. I suspect this particular model actually can't support it, because the Shimano ones that do have an extra threaded hole mine doesn't. That threaded hole allows an OEM spare cover to be screwed down to the shifter. I tried several iterations with bolt holes to match the original shifter, but it was very difficult to get this accurate & look good. I gave up & just super glued a relatively weak magnet in place. It looks a lot cleaner & I suspect it will actually work just fine, even for mountain biking. [Here are the magnets I bought.](https://www.amazon.com/10x1mm-Refrigerator-Magnets-Fridge-Whiteboard/dp/B07VPCFNKZ/ref=sr_1_7?dchild=1&keywords=magnet+10mm&qid=1607990128&sr=8-7). This may work for other models of Shimano flat bar shifters, but I would recommend the OEM cover if your shifter comes with it. The Shimano SL-M770 shifter pictured above comes with a cover attached to the underside of the indicator display. [Here is a video with instructions](https://www.youtube.com/watch?v=VCCtwLEOnAM).
