Seen any pulleys higher than 72? Goal is to do at least 5:1 ratio but with my current 15/72, it’s 4.8 
Not really in production, you can print one that’s bigger if you really need it
I’d suggest a smaller motor pulley, like 13T or 14T and an idler

Greetings sir! I saw that you were also looking for pulleys for a matrix 2 set up. What pulleys and belts did you end up going with if you don’t mind me asking?

I’m getting the ones from MBS.
Then I’m just going to keep an eye out for used metal ones or new to go on sale.

I actually ended up going with MBS 72t wheel pulleys and TB 13T motor pulley. It’ll go with this bad boy

Good call. You’re gonna need major help on belt engagement for a 13 tooth pulley. Idlers galore.
