As the title says, 3d printed on a metal 3d printer. After a failed attempt at an 80% rxm insert (holes were off on the jig I ordered 😢) I was determined to build with the parts I had already ordered. This came out great. Similar to plastic 3dp the holes were all slightly under sized but a little filing fixed that. I confirmed fit and function and now I’m polishing it up. It will be awesome when this tech is available for a reasonable price. Maybe one day 🤷🏻‍♂️. Funny enough I recently heard a story about a guy who had to be snuck into a friend’s place of employment after hours to print something similar 👍🏻
