simple pc room fans

So here we have 2 Cooler Master 140mm fans (DF1402512SELN) in a simple casing.
Just 4 parts that need printing off twice each. The 2 housings will need gluing together and the frame gluing together. Fan housing and frame just need push fit together.
No supports necessary except for "frame bar pt2" which just needs support under one end. I printed everything else with no supports, no raft, no brim. Just a skirt with line count of 4.
All sliced using Creality 1.2.3 slicer with all parts created with Freecad 0.18 and printed on an Ender 3.
You will need to cut corners off the Cooler Masters. I used dremel type multitool but hacksaw would do the job.
There's no guards or grille on back but I haven't managed to damage a finger shoved in there!
Should be relatively easy to adjust for different size fans.
I've been running one set in living room and one set in bedroom and they make a noticeable difference to room temperature. And cost virtually nothing to run.
