I have a Ride1Up Roadster V2 ebike that uses this display that is somewhat common on other ebikes. But the problem with it is the plastic is brittle and the clamp is just a bit smaller than my handlebar so you can't really tighten in all the way. I broke the clamp on my first display and bought another for $50, I barely put on the screw on it to the point where I need to hold it in place while pressing buttons so it doesn't rotate and it lasted a few months before breaking again. The displays still work fine, just the plastic on the clamp broke. You can tell the plastic on the display (top) side is a blend because it has glittery specks embedded in it. Maybe that's what's weakening it.
Sorry I rambled on. Anyway, I designed this holder to house the broken display unit after the bottom C-clamp part breaks off, keep the small hex bolt. Put the display in the printed part and screw the bolt through the hole. Then you can use a ziptie and mount the display back on the handlebar instead of paying $50 for another one that's doomed to break or use a dangling display (like I did for a bit). I added a recessed rectangle for you to add a double sided tape to it in case it rattles while riding. I had to lift the display up by 5mm from the ziptie clamp because of the bend in the Roadster's handlebar, and I do not have the skills to figure out a support underneath, so the single ziptie does mean the display is not solidly on the bar when you press the buttons.
It's best to print this in ABS especially if you lock the bike out in the sun. I printed it upside down with a raft for better bed adhesion.
