About this 3D model

My house was made with a custom air intake vent for some reason. Instead of trying to source a custom air filter I decided to take some measurements and make an adapter for the next closest size. For the most part, from what I've researched, these custom intakes are typically small ones, like mine. I've made the file parametric so anyone can go in and change the sizing based on the following parameters: Magnet Diameter Magnet Height Filter Length Filter Width Filter Height Vent Length Vent Width I also pre-split the model into full, half-horizontal, half-vertical, and quarter sized variants along with provided horizontal and vertical joiners that are glued in (and also scaled automatically).
