Winder for SUNLU filament spool

I needed to rewind some filament and had some SUNLU empty spools laying around so I made a manual winder to fit the spool as I could not find any other model that did that specifically.

I made it so that the handle slides in and clicks into place, the center rod wont go all the way through, and the main body will go through a SUNLU spool and then click into place but then taken back out with little effort.
