Printing of a Tiny Pulley Question

[curious aardvark]

That's not small - THIS is small:

Also mass produced:

The blue gears were made with colorfabbs xt (a polyester) and while only 1mm thick, impossible to bend between 2 fingers. The black rubber tyres were made with a rubber type tpu that i use for items that woud have been made from conventional black rubber. Part of my mate's house guttering is held together with parts I made from it :-)


basically - yes your pilley will be easy to design and easy to print. pla would be absolutely fine, as would pet-g and even a stiff flexible pla.
If you want to try yourself, have a look at these two printers.

and probably the cheapest ready built half decent machine around: https://www.amazon.com/Monoprice-Cal...r=8-6-fkmrnull

For that kind of item openscad is definitely the design program of choice: http://www.openscad.org/

Easier to use than it looks and once you've written a parametric script you can make different sized pulleys inside a few seconds just by changing a couple numbers.

And as the lads say, either go for a an online print agency - or, like a mate of mine just did on my bbq forum - find alocal library with a 3d printer. I made some little adaptors so you can use cheap diamond plates with a knife sharpening system - I sent him the stl and he got them printed at a local library for 40 cents an item - much much much cheaper than any online agency

What you're looking at is probably no more than a few lines in openscad, someone will no doubt run a script off for you.
We're like that round here :-)
