Color Swatch Organizer - no strings attached

Here's a neat way to keep a bunch of filament samples organized with space for labels and RFID tags.

There's a recess where you can put a label, RFID tag, Sharpie note, etc.  I originally made this because I just got an Anycubic X which requires one to hold the edge of the spool up to the corner of the printer base and slowly turn it around in the hopes that it will read the tag before you mount the spool.  With my system,  you can mount the spool first and then scan in the RFID while it's loading - how convenient!

You can stack any number of these from 1 to 10, 100, 1000?!?  The sky is literally the limit however, I think anything beyond a dozen or so might become unwieldy and should be split into smaller groups.  Then again, maybe this is the perfect opportunity for a brand new Guiness Record catagory so lets all get to work printing out swatches!

One trick I've found to get the labels off of the spools is to preheat your printer's bed and lay the spool on it with the label you want facing down.  After a few minutes, the glue will soften and you can then easily peel it off in one piece.

I've been printing them in PLA so far with generic settings.  I would make sure that the minimum layer thickness is .2, which seems to work fine. 

They click together a little stiff at first, and if you try to take them apart right away, sometimes the little curved tabs can break, but if you take some time to work them back and forth for a while to loosen them up (I think it's mostly wearing down the seam) they loosen up nicely and can then be taken apart and put back together at will.  I've included a cap and a plug shown in the last two photos for a more finished look, or you can leave them off so it can be stored on a hook.

Note - So far I've printed these on 2 Ender 3 V3 SEs a Flashforge Adventurer 5M Pro, Anycubic Kobra S1 and Anycubic Kobra X.  They all seem to work, however there are minor differences from one printer to the next.  Both of the enders worked best when I dialed the extrusion back to 94% in Prusa Slicer.  The Flashforge actually worked better with the extrusion bumped up a couple percent and that's with the Flashprint Slicer, which is unfortunate because I think it leaves a little to be desired and so far I haven't had much luck with the OrcaFlash slicer.  Both the Anycubics are near perfect as usual.  (Personally I've found every Anycubic I've bought has been an awesome value for the money!)  Let me know if I need to make any new models of these that are a little looser or tighter to work on other printers.
