I've been working on a development board for a while now. To finalize the product, some people recommend printing a case (I don't have a 3D printer). Do you have any other suggestions (the most fun ones are also welcome), or should I invest in this type of machine?

Please give me as many practical ideas as possible, I'll make my selection later.

Damn, that's a cool board.

You can order 3D prints online, check a local supplier for less environmental impact.

Or you can buy a Bambu Labs A1 mini, cheapest and easiest printer IMO.

Please don’t recommend bambu labs printers. They are destroying the open source community.

An equivalent printer would be the Prusa Mini.

Local libraries can sometimes have 3D printers.

Before you invest in a 3d printer, check your local public libraries! A lottttt of them have 3d printers these days

OK, but it works and it's cheap.

And you can use it with FOSS.

Thank you for the recommendation!
