Octopus and PI din mounted fans holder

I created this holder for my octopus pro board and rasberry pi 4. While you can just thread m3 screws directly into the holes I recommend using m3 threaded inserts. There is plenty of material around the holes so I just drilled them out to the m4 hole I needed for my insert.

July 18, 2022 update: “V3” now has different mounts for if you want the pi facing “up” or “down”.

Mar 21, 2022 update: “V2” has more clearance around the alignment collars for the fan holder to the base's posts.

Mar 18, 2022 update: added “V1” text so it it clear which version of the STL you are working with

Feb 7, 2022 update: completely redid the CAD to address some screw placement issues

Feb 6, 2022 update: recessed the screw holes and make some rings around the posts so it is easier to assemble

Jan 31, 2022 update: more feedback about fitting. Moved the Pi over just a bit as well as resized the ribs so that octopus fits better. Raised the Pi some more to allow for better cabling under it to the octopus board.

Jan 9, 2022 update: added more space between octopus standoff and fan support for mounting heatsinks
