Apple Watch wristband attachment with space for Micro SD card

This is an attachment for your Apple Watch 22 wristband for safely transporting a Micro SD card. 

Put the Micro SD card into the little compartment. Then slide the attachment over a 22 mm Apple Watch wristband with the compartment on the inside. I think that the best way to keep the SD card from sliding out  is to orient the opening toward the watch case and move it as close as possible to it (see the pictures). That should hold it very secure. I am using this since a couple of weeks and there was never a problem in any situation - just don't wear it when it can get wet or use a waterproof micro SD card - that's what I do…

I printed this on my Prusa MK3S in TPU with the narrow side down and the opening up. No special settings, no rim or support were needed. 

I included the OpenSCAD file, so it should be easy to adapt to other watches as well…
