/vr/ - Retro Games

I bought the SNAC set from misterfpga.co.uk and they came without cases. Trying the SNES one- yeah it works fine, but disconnecting the controller from the port was frightening for how much force was required vs. the size of the adapter (and doing so against a bare PCB).

Without access to a 3D printer is there anything I could use as a case? My usual approach is to just wrap everything in solidifying putty but that looks like shit so it's kind of a last resort.
