What is a niche hobby of yours that you are fascinated by and would like to share with others?
I'll start. I have recently gotten into 3D printing, and, while incredibly frustrating sometimes, there's nothing more rewarding than getting a perfect print.
Well, I got many but all just at their given time. 3D printing is one of them, but actually it became more a handy tool than a pure hobby.
My convertible car has become one, I enjoy that so much (not only the driving but the tinkering and restoration as well). I want to bring it to Oldtimer status.
I like tinkering electronics. Think of arduino projects, but most of the time without the programming.
More mainstream is baking and carpeting, but actually these are to be neglected since I am rarely able to do them due to disability.
