Dial indicator support for Tevo Tarantula

A strong, stable (very important) and very convenient dial indicator support that is set at the back side of the Tevo Tarantula X-carriage.
I use it for manually leveling the bed, and to set the nozzle height at the right distance to get a nice first layer.
This design is useful for the dial indicator that can be bought in Aliexpress http://bit.ly/2zvLmud.
The main printed part needs to replace the original back side of the dial indicator using the very same tiny and stock screws.
To hold the dial indicator to the X-carriage, I use two 6mm screws that are tightened to two internal bolts that are introduced into the piece.
To avoid scratching the aluminium or acrylic carriage, I designed and use a protective piece that is to be placed between the end of the screws and the aluminium / acrylic.
