Dive Reel

This is a dive reel design based around the small filament spool which came with my Ender5 printer. Also required are-

One 1/4" x 2.5" stainless machine screw for the center hubs, one 1/4" x 3/4" stainless machine screw for the spool winding handle, 1/4" lock nut, 5 stainless 1/4" washers to go between the center hub pieces, and four #4 x 1/2" stainless wood screws to attach the handle.

I put 250' of line on the spool to try it but it looks like it will accommodate about 400' of lightweight line.
