This reusable spool for Das Filament is simple to print, snap together and nestable making them quite convenient.

The spool consists of the same part which you print twice and then mate together by simply twisting them. There is a detent to hold them in position but you can reverse twist them to separate the halves just as easily. They also can be nestable for storage

I have included a printable snap-on label card for marking what filament is in the spool. The card also has some slots so if you remove a partially used spool you can zip-tie the label to the partial spool before putting it in storage. The card can snap onto multiple locations and on either side of the spool.

Another feature I added which is out there but I did not like how it was done on the ones I looked at was the ability to add zip-ties to the partially used filament roll before removing it from the spool. I made the side slots for inserting the zap strap extend to inside the spool diameter where there is a space for the strap to pass under the filament core. And, then I created offsetting additional space that allows the re-useable spool to be twisted and separated without interference with the now-installed zip-tie.

Lastly, I added more holes for inserting the end of the filament to tie it down. It always bothered me that some of the spools from the manufacturers have very few holes in the sides so you have to unspool some filament to reach the hole. Not a big deal… unless you are OCD. ugh.

100% printed - no hardware, fasteners, or adhesives required. No support is required.

Print Settings

For the best results, I suggest the following: Material = I recommend PLA or PETG but any material should work.
Nozzle = 0.4mm Layer Height = 0.2mm Line Width = 0.4mm Wall Count = 4 (1.6mm) Top and Bottom Layer Count = 5 Detect Thin Walls = ON Wall Generator = Arachne Infill = 40% (Cubic) Ironing = Not required Support = None required Print orientation = As per the STL/3MF files.
