Intex Hot Tub Filter Adapter

My INTEX Inflatable Hot Tub uses specialty filters which can only be bought online and are sometimes more expensive. This model adapts the filter enclosure to fit Type D Filter Cartridges which are slightly bigger, but I can purchase them locally and they're usually a little cheaper than the specialty filters.

I designed this in Fusion 360 and added a random amount of holes around the circumference to allow water to flow. It feels strong now, but I may reduce it in the future if the part becomes weaker.

I printed it in PETG. I have no idea if the material will last being in 100°+ water full of chemicals. I'll update this post later after some use.
