Modular USB, TF and SD card holder

Modular holder for USB, SD cards and TF cards. The initial series consists of 5 modules (and 4 decorative end pieces):

• The "3xUSB" module holds 3 USB gadgets with ample space for even big USB sticks.
• The "6xTF" module holds 6 TF cards (microSD).
• The "2xUSB_3xTF" module holds 2 USB sticks and 3 TF cards.
• The "4xSD" module holds 4 full size SD cards.
• The "UNI" module is just a little container for other stuff like USB sticks with an end-cap.
• 4 decorative ends with either the angled design (for the 3 first modules above) or a rectangle design (for the 4xSD and UNI modules).

Print an combine the modules you need to store your full collection of USB, SD and TF cards and extend with further modules if and when the need arise. You can print and use the decorative end pieces, but this is not strictly necessary.

Print the modules you need and make a customized holder especially for you. If you have suggestions for more modules, let me know :-)

This project was started because my own needs changed over time and nothing was really perfect for what I needed. Also, some of the holders I tried was to firm for my liking, so be aware I designed these to be a loose fit so you can remove the USB/SD/TF without holding the holder.

I spend quite some time designing the interlock - it should be able to hold the modules together as if was a single object, but at the same time it should be to take them apart. So they are very firm, but they can be put together and taken apart with some patience (keep the as parallel to each other as possible). I have been printing modules on both an Anycubic Kobra3v2 and a Bambu A1 mini and the modules fit together even when not printed on the same printer.

There are a 3mf file for printing all the 4 end pieces which can be used for the other modules as well. But in any case, the print settings used are 0.2mm layer height, as line widths set to 0.4mm and elephant foot compensation is set to 0.1mm for 1 layer.
