Focuser for Pierre Strock telescope

This is an upgrade of : 2in Crayford Focuser (https://www.thingiverse.com/thing:4424419) 

It is compatible with Pierre Strock telescopes. I had a few items that I wanted to upgrade to make it 100% compatible with my use. 

Upgrades: 

 -5mm oblong hole for the recoil rod.

 -A modification of the plate.

 -The focuser is reinforced by two lobes next to the bearings. Their goal is the avoidance of a central arch above the bearings

-Best filling for screw and nut.
