Free Tools & Spare Parts STL Download - 12v fan adapter for 4" hoseby Maudlin Modellers

I wanted to make an adapter for the Rear Vent to 4" Adapter for Anycubic Photon by DocTanner (https://www.thingiverse.com/thing:2877754) This allows an in-line fan made from a power supply 12v fan to fit inside, with a switch, and 12v power supply wire. I am planning on using small bolts and nuts, though i could also use zip ties to attach the two halves together. I printed these using a Creality Ender3 Pro, with Skirt and Buildplate supports.
