64-65mm, 94mm, and 96mm piston ring compresser

I got tired of the mess and frustration to install the cylinder over the piston when doing a top end so I made this tool. It's for RM250 64.4mm piston but will probably work for slightly larger and smaller pistons.
I made the prototype out of PLA but I'll most likely make the next one from ABS(The PLA part warped some when I left it in the sun)

Just add a M3 X 20-25 screw and compress the rings with a zip-tie around it all. Then when cylinder is over the rings then just cut the zip-tie.
