Most versatile design I’ve found so far. Excellent work, thank you!
Elegoo Matte PLA

A little snug on my USB-C adapters in a couple of them as well as the regular USB slots. I think I will probably blame the filament for that as it is really old (7+ years old) Inland PLA from Microcenter. I just "stretched" out the slots with a pair of needle nose pliers and all is well.

Most USB thumb drives fit great. A few that are slightly bigger are very snug, but they are snug in the PC‘s USB port as well.

Positives:
- Printed well
- Very modular
- Holds pretty much anything I could ever need

Negatives:
- For some USB A sticks its a extremely tight fit
I´d add like 0.1 - 0.2 mm more tolerance for the USB A slots.

Works great. Good fit for the USB items, without being too difficult to load/unload things. Thanks for sharing.

Tolerances are perfect and the design is ingenious!

Printed without any issues in white PLA by local manufacturer. Thanks!

Super model!!!
I printed it on my P1s without any problems.
Tolerances are great, it looks awesome and thanks to the f3b file I was able to modify it even further.
I hope to find more people sharing their actual cad models in the future. And not just their stl.

Thanks a lot

Very nice. I think the usb flash drive hole should be a bit larger

@moesch_1414501 i could do a looser fit version, i also think about a small chamfer for easier insert of flash drives
