Screws-only version for Copperhead Hotend Fan Shroud

This is a quick remix of Cris Persi's nice fan shroud for the Copperhead Hotend on Prusa Mini. It works with 2-4 screws, no threaded inserts needed. More sturdy than (but compatible to) JASII's version, less vibrations.

Thank you JASII and Cris Persi for your designs! 

I printed in 3DJAKE TPU A95 and the M3 screws sit nice. Maybe you need to drill the holes, pre-thread them or you use nuts on the other side.
