I designed and made this because I wanted a safe place for my Micro SD cards, they are way too tiny and too expensive to loose.

The holder is threaded so that when the slider is clicked shut the two parts become inseparable. There are notches in the slider mechanism that keep the slider in place and stop it moving around.

I allowed 0.3mm tolerances almost entirely around the product so that the thread would fit correctly when taken off the printing bed, this however could be different for you.

I've printed this now in PLA and CPE, both materials have worked well coming straight off the printing bed and fitting without any adjustments. The thread can be quite tight depending on the quality of the print.

It took 8 hours to print all three components.

Would love some pointers if anyone has any!

Enjoy!
