This reel was missing an handle as long I can remember, decided to take care of it.
Simple handle, no moving parts, but a lot more practical than without the handle.

After fitting seems a bit fragile on the connecting part, but seems to work for a print only solution. If it breaks I'll try a different solution using a screw as axle and creating a hole for a nut on the handle.

Feel free to remix, change, whatever and share...
.step file and .f3d file included.
