Bumper Case for Onefinity Touchscreen

I’m pretty good at breaking phone screens and whatnot. And the shop is a dangerous place for a screen. So I designed a protective bumper case to fit the touchscreen. It’s printed in flexible TPU and stretches around the screen. It should be enough to protect against a fall to the floor if I happen to knock the screen off its mount. Hasn’t happened yet, but now is the time to protect against it.
The only flexible filament I had on hand was bright blue. TPU prints slow, so I used a .8mm nozzle and .5mm layer height to make a functional, if not slightly ugly case. Even my fat fingers still have good access to the buttons and all corners of the screen itself.

@muddyfeet this is great, thanks for sharing! I’ve only had my machine for a couple of days but already had a few close calls with dropping the display while getting everything all set up. I just recently got a 3D printer, haven’t tried TPU yet but this seems like a good reason to buy some!

Excellent. Beware that flexible filaments can be some of the most difficult things to print. My best trick is to drop speeds by a lot.

If I were to make this again, I’d probably scale it 2% bigger in all directions: it was a real tight fit over the screen.

I do not have a printer nor have an interest. And I can drop/break things with abandon. Eventually, I will have my machine with the 10 inch screen. Do you sell these protectors?
