Tevo Tarantula Pulley Bearing Spacers

Tevo Tarantula is a nice entry level DIY 3D printer, but there are a few points that should be addressed. The good part that these can be corrected printing some parts. The worst, in my opinion, are the bearing spacers for pulleys. In this printer, pulleys are attached to M5 or M3 screws, but curiously all spacers are the same size, and don´t fit to the inner bearing part. So, I´ve created these simple spacers to replace the standard ones. These were inspired in Pulley Spacers from Noumcreation,
