The rest arm of my Technics SL-D2 turntable was broken. Took the thingiverse stl available and remixed it by extending the shafts to make it work with the SL-D2 model. 

Attached is the image of what the actual arm looks like but I am not good at remixing, so all of the measurements are done through a visual. Looks close enough and works for the intended purpose. 

Original Technics part number: SFKU212-01E

Should work for the SL-D1/2/3 models of Technics turntables, maybe others as well. 

Note: The clip from the original model works fine with this. Used a paper clip as the hinge.
