Summary

I remade my old USB holder. The reason is because i got more micro SD cards, some SD cards, and a few more USBs.

I understand this is not the optimal way to hold all of this; HOWEVER, i really enjoy the USBs being at an angle and all the SD cards being in their own spot.

This model will probably need supports for the T-Slot. Other than that it should be ok.
72mm Length, 24mm High, 26.5mm Wide (from after the T-Slot)

UPDATE!!!!!
The file before 2/28/2021 had a wall that was too small (on the SD card slots). I have increased the thickness so the slicer will actually print it.

Feel free to use my step file to change the dimensions or if you want to cut a piece out. If you publish something based on my design please include me.
