The file 'Adaptors To Use Metallic Gears (motor- Rear Axis) 3D Printer Model' is (stl) file type, size is 427.9KB.
After some printed gears breaks, I designed and assembly some parts to work with metallic gears from Aliexpress.
I also adjusted the Ø of the rear shaft to the main gear Ø.
I share with you the references of the purchase items.
Motor gear (13T 3.75mm): https://es.aliexpress.com/item/1005005403726420.html?spm=a2g0o.order_list.order_list_main.10.3899194d86u0OU&gatewayAdapt=glo2esp
