Technics SL-1200 dust covers are hard to come by, but Reloop has one that almost fits, the hinge mounts will not work on a Technics. This is a hinge adapter that will work with an SL-1200 MK5. It may work for other SL-1200 versions, but I don't have any to try it out on.

This requires:

• Technics SL-1200 MK5 turntable
• Reloop Dust Cover for Reloop RP2000 and RP4000
• 4x M3x10mm socket cap machine screws
• M3 tap (to tap out the un-threaded hinge mounts on the MK5)

Assembly is fairly evident:

• Tap out the un-threaded hinge mounts on the turntable
• Attach the hinge adapters
• Insert the hinges into the adapters
• Mount the dust cover

The model was made in OpenSCAD; I didn't bother making it work in customizer, because I don't imagine there's much need to tweak it (and, customizer is a hassle since it only supports a single file, yet I use some libraries I've written) but you can get the OpenSCAD file on my github.

Unfortunately due to the depth of the hinge and the lip below the hinge mount on the MK5, this adapter shifts the hinge backwards about 1.5mm from where you'd ideally like it. I may make a revision some day that notches the hinges that came with the Reloop cover, but this was more modification than I wanted to do. Really it's no big deal: you'll never notice the 1.5mm shift anyhow unless you look for it.
