Summary

This holds the dock for the Square Card Reader,
I included the business card holder that fits in the slot on the rear right to hold square business cards upright. The business card holder itself fits 2.5 inch square business cards (not traditional business cards).
I printed with PETG since I'll be travelling year long and don't want it to melt in the car but you can use the material of your choosing.

Feel free to leave comments or redesign what I've come up with.

Thanks.
This is my first design so please be gentle.
