OnePlus 12 TPU Case + Quadlock

TPU case for the OnePlus 12. The cutout in the case is meant to fit a MagSafe magnetic ring for compatible accessories and wireless charging, I got mine from here. 

There are three versions of this case, one has a ring around the camera cutout and the other doesn't. The one with it requires supports, and both are printed in the default orientation of the file. 

New for V2 is a Quadlock variant, which uses this file from Potatetoe_Tractor on Thingiverse. Thank you for the files! This variant requires you to print in both TPU and a hard material such as PLA. You can do this automatically with a tool changer, AMS w/ compatible TPU, etc. To do it manually, follow these steps (for Orca or Bambu):

• Open file
• Orient file to face the Quadlock side upwards
• Enable automatic normal supports (they are easy to remove with 95A TPU, don't worry)
• Add another filament corresponding w/ your desired hard filament
• Use the height change tool to paint the hard filament onto the Quadlock adapter and camera bump
• Slice the file
• Use the bar on the right side to find where the layers change from TPU to your hard material
• Right click to add a pause on the layer you found
• When the print gets to that layer, it will pause and you can manually switch your filaments

CHANGELOG

09.28.25 - Added experimental flush Quadlock variant of the V2 that shouldn't need supports. It's a big boy! 

06.07.25 - V2. Sides of the case now give room for the curved edges, and the rear camera holes are nicer and simpler. Added Quadlock variant.

02.10.25 - Added STEP files.
