Summary

G'Day.

You can use this Ashtray with Magnetic Clips (4pcs. 15mmx2mm) or with
a spinning Stand (Ball bearing: 8/22/7) or without all of them just normal...

Disclaimer: It may be dangerous, using some Plastics for an Ashtray.
I use PLA/CF and at least 3 Coats of Heat Resistance Paint Coat.
