Anet A8 X-axis and Y-axis tensioners for 20T x 3mm toothed idlers

I decided to upgrade my Anet A8 X-axis and Y-Axis belt tensioners for 20T x 3mm idlers.

Many discussions about which is better, smooth or toothed, but I'm not going to get into that here.

If you choose to go with 20T toothed, these prints will work well for you. You can get these 20T idlers from various places, Amazon, Gearbest, Banggood, Aliexpress, etc. As long as the width of the pulley is just under 9mm (pretty standard), these prints will work.
