This is a remix of the original USB Case made by PoRast. I just tweaked the dimensions a bit as I found the original pieces fit too loosely and easily slid off if mishandled, now it's very snug and not prone to doing it's own thing. I printed on my A1 using PETG HF (Bambu  settings). You can use whatever material you wish, I just went with PETG (for heat resistance, I thought ABS might be overkill) as I will be using it inside of a PC (near a fan) case to hold a USB with all needed drivers and OS for a customer's custom build PC.
