# iPad Pro Bumper ## Overview 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!   ![3d_printing_heropad.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/232/medium640/3d_printing_heropad.jpg?1542679596) ![3d_printing_play-loop.gif](https://cdn-learn.adafruit.com/assets/assets/000/066/233/medium640thumb/3d_printing_play-loop.jpg?1542679615) ### USB C to Micro B Cable - 1 ft 0.3 meter [USB C to Micro B Cable - 1 ft 0.3 meter](https://www.adafruit.com/product/3879) As technology changes and adapts, so does Adafruit!

You'll need to adjust your settings accordingly if you're using material different than PLA. **CURA 3.X Slice Settings** - 225C Extruder Temp - 60C for heated - .4mm Nozzle - 0.38 Line Width - 2 shell count - .2mm Layer Height - 10% infill - Support Material On - 25mm/s default print speed - 8mm retraction distance (bowden) ## Flexible Filament   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.    ## Bed Adhesion   60C temperatures for heated beds. For non-heated beds, PEI sheet and blue tape works well. ![3d_printing_cam-bump.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/235/medium640/3d_printing_cam-bump.jpg?1542679815) ![3d_printing_back-bump.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/236/medium640/3d_printing_back-bump.jpg?1542679845) ## 3D Printer & Slice Setting   Follow your printers recommended settings below for a good starting point.  ##   ## Print Hotter TPU extrudes best at 220C-225C temperatures. It has a higher melting point and requires more heat than regular PLA. ![3d_printing_buttons.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/237/medium640/3d_printing_buttons.jpg?1542680026) ## Clean up   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. ![3d_printing_support-remove.gif](https://cdn-learn.adafruit.com/assets/assets/000/066/238/medium640thumb/3d_printing_support-remove.jpg?1542680119) ![3d_printing_support-remove2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/239/medium640/3d_printing_support-remove2.jpg?1542680148) ## Featured Products ### Adafruit NeoTrellis M4 with Enclosure and Buttons Kit Pack [Adafruit NeoTrellis M4 with Enclosure and Buttons Kit Pack](https://www.adafruit.com/product/4020) So you've got a cool/witty name for your band, a Soundcloud account, [a 3D-printed Daft Punk helmet](https://learn.adafruit.com/3d-printed-daft-punk-helmet-with-bluetooth)... so what could be missing from your road to stardom?
