M42 to Sony a mount (helios 44m to sony alpha mount adapter)

thingiverse

my new helios 44m did fit some of the adapter's and the best one was the one i remixed from, but with one issue, the helios didnt go deep enough to the sensor so it focused max 5 meters, so i sacrificed the locking mechanism for infinite focus.Camera used with helios - Sony a57 IMPORTANT:Some slicers will ask you if you want to repair the model, DON'T do that, it can mess up the print.I made a before (with the model i remixed from adapter) and after (with new adapter) pictures to show how it looks.EDIT:after almost a week of using this adapter, i can say that it is a bit flimsy and can make the lens come off if unscrews itself. Be carefull while using this.
