I printed the great Steiner 3D prop gun revolver Magnum .44 and it is a great design.
Unfortunately I could not go to the hardware store to buy screws to put it together. So I went tot the catalog on Fusion360 and downloaded the srews I needed.
Printed them out and cut to length. I drilled out the holes a little since the screws can't cut thread. Dit not need any glue either. Just pushed in the screws and it works great!!!
Note: If you cant find the Steiner Prop Gun anymore, you can still download it via this link: https://web.archive.org/web/20220603083031/https://www.thingiverse.com/thing:3004363
