16T is a bit loose on a LDO motor shaft

Bought both 16 and 20T pulleys in black. Finish is great and anodized pulleys wear better than raw alu. The 20T 5mm bore fits perfectly on the motor shaft but the 16T's are a bit loose. This can cause a small wobble but I used them on the Z axes so not that important. I've bought 16T before and the fit on the previous ones were better.

Strong idlers that work very well

Great fit and finish

These pulleys and idlers have a great fit and finish, and will make my build look great! I’ll be curious to see how well the bearings hold up on the idlers.
