The original stand kept falling over, so I designed a new one.

The pen I use:

prints in ~2hrs, heat resistant filament is recommended, but for now regular pla seems to work too, it deforms a little from my pen, but not that much.

There are two versions: the one in the photo and an alternative one with bigger holder for larger pens.
