Filament spool, 2 pieces, threaded

My local Microcenter has started selling reloadable spools and filament not on spools. They sell the reloadable spools for about $5. Their 2 piece spools use two nuts and hex head bolts to assemble and typically one of the nuts will fall out as you assemble or disassemble. I decided to make my own that just uses large threads. I did, and they work great for me.

I am uploading several designs. The pairs have the same name with F or M for male or female. You can mix and match across the designs, just choose an F and M.

You do not need support for these, in fact, do not use it. I print these out of leftover filament or filament I am unlikely to use and will pause the print and change filament if the first bit is running out.

Mine are printed on a Prusa MK3.

As you can see from the video, the two halve spin together very easily.

They print fined on Fast, Medium or mixed settings. I print mine on Simplify 3d fast but increased fill to 20%.
