The Baader UFC case can now be ordered or is available free of charge as a 3d printable file. This can only be assembled with a little more mechanical skill, as you have to cut an M4 or M6 thread on the underside of the case in each case. You will also need the appropriate screws, which you can normally buy at a DIY store. We do not deliver screws matching the print data ourselves and ask for your understanding.
