This adapter enables this generic soldering iron stand to work with the Pinecil, otherwise it would just fall through.
It uses a standard 608 bearing as a metal contact and heat isolator, that should press tightly in place. The adapter itself should also be a tight fit into the stand.
I printed it using ABS for better heat resistance, but it doesn't seem to be warming up, so PET-G might be sufficient too.
The author marked this model as their own original creation.
