In this project we'll 3d print a bumper for the 11" iPad Pro (2018).
This bumper is 3D printed with flexible filament and will protect the edges and rear facing camera.
The design features a cutout for the USB-C port. Beveled buttons on the side allow easy press of the volume controls.
The frame is padded for protection and allows the tablet to be flush when placed on a flat surface. No more camera bump on the back!
NinjaFlex colors are available in the Adafruit Shop!
The 3D printed bumper is fairly easy to make with most common FDM style 3D printers that on the market.
And if you don’t have access a 3D printer, you can order our parts by visiting our Thingiverse page and have a local maker 3D print the parts and ship them to you.
Download the STL file and import it into your 3D printing slicing software. You'll need to adjust your settings accordingly if you're using material different than PLA.

TPU (thermoplastic polyurethane) filament is a flexible material that's ideal for gaskets, plugs, leveling feet, and mobile device cases!
There's different types of TPU, some which more elasticity than others and others with more grip.
60C temperatures for heated beds. For non-heated beds, PEI sheet and blue tape works well.
3D Printer & Slice Setting
Follow your printers recommended settings below for a good starting point.
TPU extrudes best at 220C-225C temperatures. It has a higher melting point and requires more heat than regular PLA.
We used a flush diagonal cutters to clean up support material around the inner edges.
Make sure the openings for the mute switch and USB-C ports are cleaned before plugging in cable. Use a hobby knife to help cut away stringing that could block the volume switch.
