Commodore C64 Breadbin Broken Rear Case Clip Replacement

Recently bought a C64 on ebay, unfortunately the clips that hold the rear of the case on tight are snapped off. I designed this small clip to replace the ones that have broken. It fits between the sides of the original clip built into the case. The C64 is a 1983 Original breadbin model It holds the case on nice and tight. Use grey to print it for that authentic look. Installation instructions, put the clip with the knobbly bit pointing towards the inside, get a pen and mark where the case ends, this is on top of where the case indents but not on top of the inner lining. I used some super glue to carefully stick it on. *I wonder if it could be improved by the part following the contours of the original clip.. All my clips are broken so i had nothing to compare it to. * I have updated the design so it should allow more flex,
