Snatch blocks are awesome!
If you don't know what a snatch block is, you're going to like 'em too; they're pulleys that you can split in half, load some sort of cable through them, and hang them anywhere!
I can't explain it super well, but Destin over at Smarter Every Day sure can: https://youtu.be/M2w3NZzPwOM. (He even printed some of the parts he used to demo.
These snatch blocks are really just for show, but printed in PETG, they can support a bit of weight. I printed the sides in Overture PETG Space Grey and the wheel in AMZ3D white PLA. These things are super small and I even printed the whole thing on the MP Select Mini (and it's only 120mm in all directions!) I think you'll love these little guys and they're awesome for teaching kids about simple machines.
To put them together, push the wheel over the half with the larger core. Once those are together, push the smaller core through the wheel into the smaller core. Make sure it's straight! It'll have some resistance, but once it clears, you'll feel it: it'll spin freely.
Layer heights can be whatever you choose, but infill should be about 20%. I used cubic infill (because it's the best :) and you won't need any supports.
