I really liked this model https://makerworld.com/en/models/1306598-h2d-h2s-poop-chute?from=search#profileId-1340055 for the waste disposal unit for my new H2S. I have a lot of magnets from my projects, so I decided to make an adapter for this great model. The result is an adapter that fits the original model without glue and is very tight. It can be removed or the magnets replaced.
