About this 3D model

@DocTanner created a nice Rear Vent duct adapter for the Anycubic Photon. You can find it here: https://www.myminifactory.com/object/3d-print-64661 . I just wanted to have an Addon for it to add some filters (Hepa, Active Carbon) in the first part of it and a 12V PC Fan 120mm. So i created a nice little Addon to hold the filters and the Fan. This Addon is for a 120mm fan. Between the two grills is space for the filters and will hold there. To hold the Addon on place and seal it, i used Hot Glue, so i have a tight seal and can access the filters anytime. You could make a holes to both to screw it, but i don't recommend it.
