prusa i3 Zonestar p802 40mm fan cover and endstop

this is a fan cover and endstop plate for the prusa i3 Zonestar p802.

I created this to deal with an issue I had with my massive fan duct.
This moves the x endstop ~26mm further away.

eventually I changed fans (to one that's 2mm thinner) and did a few other mods and cut away the can cover section, the old fan grille then fits on top fine.
