Brass heat-set threaded inserts with a deep black-nickel coating that won't fade with heat. You melt them into a printed part with a soldering iron; as the plastic re-solidifies it locks the knurled insert in place, giving you a strong, reusable metal thread instead of tapping into plastic.
The Voron spec is M3x5x4. Other sizes follow the dimensions used in popular machines and components, including the Milo Mill and XOL. The standard way to add durable, re-openable fasteners to any printed assembly. Sold in packs.
These things are the best. Really take a project to the next level, no one likes seeing brass peeking out of your printed parts. Stop being a chump. I’ve got like 300 of these, they’re consuming my life.
You should write my product pages. Glad you like 'em! Thanks for the order.
Black and not brass colored, not much more to it.
I'll never use another heatset. These are too beautiful
