Z axis support

thingiverse

Stabilize the Z axis with a wooden dowel as a connector to boost reliability significantly. A 10mm wooden dowel is ideal, but any 10mm rod can be used effectively. Secure the connection with three 12mm screws driven into both the wooden board and the dowel for a solid hold. This mod should work well on the Tevo Tarantula, and it's likely compatible with other printers that use a 2020 frame design.
