found a couple that u could download but none i was able to find looked like they was printable so i took those an tinkercad an made my own using the ones i found as reference an it takes a 608 bearing an it works great. holds 18 collets or any r8. im already working on another that has the carousel hanging from the mount instead of sitting on the mount so the mount will be above the carousel an should be alot smaller than what i have on this one. may be able to make make this ones mount alot smaller as well but i'll upload it as a different thing once i get it done.
