Stackable Sample Master Spool - Suitable for Mini(+)!

                                                      Final version released.

• Changelog:
  • Added inner ring for using in other types of spool holders;
  • Added 2 snap joints for a more secure fit when winding/printing;
  • Corrected bottom part height to match top part;
  • Corrected size of joiners, now 2 joiners should hold 3 spools together;
  • Readjusted to 25% honeycomb infill, 30% was a bit too much.

This spool will fit AT MOST 50 grams of filament and I highly advise that you wind it up yourself to prevent tangling (common with samples on my experience).

The design itself is pretty simple:

• Made of two parts that snap together to create a spool;
• There are slots on the inside of the spool that allow you to use joiners to connect multiple spools together (so you can have all your samples in one place)!
• Make sure you wind your sample on bottom or you won't be able to snap it after!

It works perfectly alone on the mini bearing spool holder and I'm sure it'll work equally well on most other holder styles. I'd say having 2 or 3 together will provide more vertical stabilization and prevent it from topping to the side (didn't happen to me though but I wind samples very neatly, it is possible if using only a single spool, it's thin).

I printed the one on the photo using PETG.

A 3MF is provided with all my printing settings including the honeycomb looks but, again, bare in mind I use a 0.6mm nozzle so change settings accordingly (and make sure you're not printing everything in one go, that'll be a big mess! Select the parts you want and hide the rest).

Or if you'd rather do your own slicing, STLs are obviously also provided (Top needs reoriented).

I hope this helps you as much as it helped me, because it is a hell of a difference to print using samples on a spool! :)
