Finally upgraded my phone again after 3 years - this time I went cheap with the base model of iPhone 17, so here is a bumper I created for myself and you!

I have tweaked around the buttons so all of them are easier to press down (except the action button), and made it easier to slide your finger over the camera button or light-press on it.

The lip on the top of the case makes sure when the phone is put down on a rigid surface, the camera would not hit the surface, and prevent the entire phone from teeter-tottering.

Update:

• Added more refined details to the model for better feeling

----------------------

To install, fit the top two corners in first, then one of the bottom corners, then force the last corner and push it in. It's a snap-in design so you'll have to force it.

Slicer Settings

Make sure the long sides are on the less-ripply side of your printer, unless you wanna see more ripples on a big surface every day.

In order to successfully print this one, here are some of my suggested slicer settings:

• Layer height: 0.16mm (you can go from 0.12 to 0.3mm)
• Support Pattern: Zig Zag
• Support Wall Line Count: 0
• Support Infill Line Directions: [45]
• Support Z Distance: ONE layer height
• Enable Support Brim: Yes (Recommended, not required)
  • Support Brim Width: 4mm

The support settings is to make sure the support is easy to remove, still retains its integrity, while prints relatively fast. Otherwise with a support that's too strong, you risk damaging the print itself.

To safely remove the support, first press it against the bumper body instead of trying to peel it away all around the model, the carefully try to remove it from the loose part. Stressing the open ports too much might end up cracking the print, so be extra careful if the support doesn't want to let go! Make sure to clean up all the supported interface of any remaining extra material, which will ruin the fit.
