Z 3 wheels guide v3 (D-Bot)

***********************************
I leave this 3-wheel system published but just for Solidworks files that may interest some of you. For my part I will go back to a 4-wheel system

First of all : thank you spauda01 & NickRimmer for your work and for sharing it.

Just few changes from the original design :
- the distance between wheels increased to 32.20 mm
- larger hole in tensioner for the nut
- other minor changes
