Samsung Galaxy S24 Ultra MagSafe Case - SnapArmor

This is a SnapArmor MagSafe phone case for the Samsung Galaxy S24 Ultra. This has to be printed with flexible filament.

Please post photos of your makes! I would love to see what prints, colors, and variations you guys end up making :)

If you have any suggestions for improvements to the case/any features you want added, or have any issues with printing, feel free to leave a comment or message me directly! I have been printing with  TPU/FLEX for years, and I am happy to help with any tips or directions. 

To add the MagSafe magnets, you must purchase the magnets that look like the magnets shown in the pictures. They can be bought from many sellers on amazon, or from AliExpress. To install them, you need to pause the print at the layer height just before the bridging over the MagSafe area (if you are generating your own Gcode and not using my presliced files), and once the printer has paused, place the magnets in and hit resume. Additionally, if your printer attempts to place supports in the MagSafe area, you will need to put a support blocker there. 

Please check the MagSafe installation image for the proper orientation of the MagSafe magnets.

IMPORTANT: if you do not install the magnets in the proper orientation, it will interfere with your Spen. This case has been specifically designed so that the Spen functionality is still 100% usable, provided you orient the magnets properly. 

To make it easier, I have generated Gcode for both 0.4 and 0.6mm nozzles that incorporate the proper pauses, proper support blocking, and specific variable layer heights for ideal quality printing.  I have also included multiple different files, each with different infil patterns for the back design. They will be named based on their infil pattern.

My Gcode files also include the very specific TPU profile settings that I have built up over my years of printing TPU, with special regard to the supports. With my Gcode profile, you should be able to print it as is, and the supports should be removable with just a small bit of cleaning afterward. This should yield the best overhangs for the top and bottom lips. Bear in mind, that these settings are fine-tuned for my Prusa MK3S+, and I cannot guarantee the same quality on other machines. 

If you will be generating your own Gcode, you need to ensure that the top and bottom lips are properly supported, as your printer will most likely be unable to bridge that overhang properly. To generate a “patterned” back design, in your slicer, change the bottom layers to “0” which will remove all solid bottom layers, and make the infill your bottom layer. This will make your infill pattern show as the bottom. Then change your infill pattern to whatever you would like to show.
