The Problem
The Avenli Vermont inflatable hot tub ships with a filter cartridge (marked "Type 2") that doesn't quite fit standard sizing, it has a smaller bore and different ring placement. Replacements are harder to source, more expensive, and limited in options.
The Solution
This 3D printed adapter lets you use a widely available Type VI filter cartridge in your Avenli hot tub with no modifications to the tub required, it just screws on the existing nozzles. Type VI filters are stocked at most pool and spa retailers and are significantly cheaper and easier to source than the original cartridge.
How It Works
The adapter threads directly into the M62×3 filter housing on the tub and accepts a standard Type VI cartridge. It consists of a threaded barrel and a locking flange that work together to create a secure fit.
Print Settings
Material: PETG or ASA recommended due to chemical and UV resistance
Avoid PLA, it will degrade quickly
Infill: 20%+ recommended for thread strength
Supports: Required on the base
Notes
Verify your hot tub's filter housing threads are M62×3 before printing
Tested on the Avenli Vermont 17654US
Type VI filters are available at most pool supply shops and department stores
Optional 3mm spacer available for some filters that are slightly smaller.

Why I Made This
Replacement filters for these tubs are surprisingly hard to find. Type VI filters are on the shelf at most stores. This adapter makes maintenance much easier and cheaper to run the hot tub. If it saves you a headache, give it a like.
