Just gathering all the bits for a tumbler build, Has anyone tried the 3d printer belts with the "toothed" pulleys. only disadvantage i can see is they may provide to much grip in the advent of a shaft seizing etc.the main advantage i see is that they will provide no slippage which causes friction heat and destroys rubber belts.I am talking small tumblers here.link is just for the pics. aurarum.com.au/product-category/accessories-and-parts/pulleys-and-belts/

Question, what is your idea of size of a "small tumbler"? It looks to me you are trying to spend a bunch of $ for parts that really aren't necessary. V belts have worked fine for many years for thousands of people. Any friction caused heat with a small tumbler is likely too small to measure, and if it is set up right there is virtualy no slippage. For a small tumbler use 3L {3/8" wide} belts and pulleys instead of 4L {1/2"}, less power loss, and a more flexable belt. Another likely over expense would be the shaft material, metric here is way higher than inch measure, and the link you put up shows all metric puulley bores, the 10mm being a minimum size for even a small machine. Cost everything out with your printer parts idea, then with v belts, pulleys and inch measure shafting and bearings, then please do come back here with your result, I'd like to know.

Thanks for your reply,I am in remote Australia and we are metric,The type of tumblers i am talking is something around 2x4 pound or a tad larger the issue i have with v belts is that of supply as we don't have a local bearing shop but a couple of electronic shops that stock a lot of 3d printer belts and pulleys.

I didn't know you are from Australia, makes the whole subject different. If it works for you, and I know you folks graduated to the modern era and went metric some time ago unlike the US, go for it.

Don't get me started on our half baked metric system,3/8= 9.5ishmm.so nothing converts.throw in i have two old landrovers that i am trying to restore that have whitworth and some AF bolts[sometimes] it is trying.and then being "down under"our tumblers have to turn the other way.
