Samsung Galaxy Z Fold 3 - S pen attachment (requires Spigen Slim Armor Pro case with Hinge protection)

thingiverse

This is a S-pen case/holder for the Samsung Galaxy Z Fold 3. It mirrors the original design from Samsung with the "flip" case that was released at launch. I love the design but hate the case. This solution requires the Spigen Slim Armor Pro with Hinge protection. Basically the Front case has a hinge built in to open/close with the phone and rotates/pivots on the front case. Printing this should fit the hinge protection perfectly. Note - The model has a built in support, under the "arch" to match the curvature of the Spigen hinge design. It has a 0.3mm air gap between the base and the s-pen holder itself. Most printers should have no problem with this and the lower/bottom portion should be able to be removed easily. If you have a dialed printer you can print without supports on your slicer. I however have been unsuccessful at this, since the walls of the cylinder (s-pen) are quite thin. They always collapse and I can't get a strong layer. So I had to use a support inside. I included a file that has built in supports with a 0.3mm air gap on the top and bottom. Worked great for me. If it doesnt, use the model without supports and use your own slicers settings that work with your printer. I printed the model shown in the pictures with eSun TPU at 2.4mm resolution. This can be applied to the phone with double stick tape or a thin layer of hot glue, so its removable without damage.
