Saitek/Logitech X52 Spring Preloader - Large

Simple design for fast print - measured the spring and stick dimensions and designed the biggest compression block I could fit while still having movement in the spring and being able to fit the block over the stick. requires a bit of force to snap the block around the stick, just give it a shove and it'll snap on. Square channel up, round channel down. 

prints without supports, round channel down. I printed at 0.2mm in PLA with no issues.
