maybe you know the crazy invention Freutoy, which is a butt plug where panties or underwear can be attached.
If not, I recommend you check out the site and these videos:

Unfortunately, the product is very expensive, so I've been looking for alternatives for quite some time.
In fact, there are already printable files from the Freutoy, however, I don't think the plug from PLA is as nice as from metal.
Now I have come up with an idea, which unfortunately I can not implement with my existing skills.
It would be interesting if you could develop an attachment for the stem, which could be integrated on a plug like this one:

A simple idea in my head could look like this.
Unfortunately I can't do CAD design and have to rely on help here.
Would anyone be interested in this project?
Kind regards
