I have an adapter part that was 3D printed. It was purchased long ago and works great, but it has cracked and I have no way to replace it. Can this part be reverse engineered? Do 3D printers do that? Can it be measure and duplicated? Approx size is 2”x3”. If not, best solution? Take it to a metal shop? |

Post a picture and the dimensions. Then post it Here and someone might be able to help you. |

Quoted: If it was 3d printed once, I’m sure someone could duplicate a similar part. 3d printers don’t have a scan and print ability, so someone would have to do the design work first. True but 3d scanners are becoming more common and the lidar on new iPhones I hear do decent |

Quoted: Picture of widget? Get an adapter that connects a CZ scorpion to a Mac 11/9. Attached File Attached File Attached File Attached File |

You either need the file from the creator, which could be loaded onto a printer and printed again. Or failing that, someone would have to take a bunch of measurements off of it and re-create it in CAD from scratch. A machine shop would basically do the same to make it from machining metal. |

What he said. If I had the part in hand I could measure and recreate. |

Quoted: Looks like whoever printed that, printed it in a less than optimal orientation. That being said, it's probably not a great part to make from hobbyist FDM printing in any orientation without accepting it will be semi-disposable. |

Quoted: I disagree. As it was printed, the layers are perpendicular to the clamping force of the stock attached to it, which is a bit stronger overall. Had it been printed laying flat, the weak layer lines would have been in-line with the stock clamp and it likely would have snapped clean off with a bit of side loading on the stock. That being said, it's probably not a great part to make from hobbyist FDM printing in any orientation without accepting it will be semi-disposable. After taking a closer look, I see exactly what you mean and rescind my previous comment. You are absolutely correct! |

Quoted: What does the attachment point on the stock look like? is it just Pic or what? or does it just slide in on both sides? Like a big ol clamp? The back of the Mac 11 is just a metal plate attached to the two forks that slide in. That plate and lugs are locked in, then the adapter piece comes into play. The adapter piece sits flush back to back with that metal plate and is held in place by the two screws, which are the two holes in the middle, where the crack is. Then the regular CZ stock and stock adapter slides down from the top over that adapter plate, you push the button in, and slide it completely down, and the button pops out and secures the CZ stock/adapter in place. |

Yea man, there are a ton of Mac specific stock adapter files out there but cant seem to find one for the EVO stock. and a bunch of Evo adapters to change the stock on a evo. Dont see the combo you are looking for. If you find the file id be happy to print it for you for no charge. The other options is to find someone willing to measure it for you and cad it out. Im not good enough at that or id offer to do it for you. best of luck dude |

Quoted: This. If it cracked once, build out of aluminum. Quoted: Quoted: Looks in good enough shape to sand cast a duplicate in aluminum and then drill the holes after This. If it cracked once, build out of aluminum. So just take this to any metal shop and they’ll know what to do? |

Quoted: So just take this to any metal shop and they’ll know what to do? Yeah it's worth a shot. They probably have people coming in with plastic parts to be turned into metal frequently. It just might not be cheap. They might also ask for the file and tel you it is cost prohibitive to make it. So be prepared for everything. |

OP problem you will have is the $$$ for design and a print, which you will have to verify and approve, then $5 of aluminum and 3 or 4 ops at say $80 an hour, easily a $500 part for a job shop. This would lend itself to finding a friend with a Bridgeport in their garage |
