Barrel Mounted 9-11mm Dovetail rail
Description
For mounting a dovetail optic on a barrel. Either on the end of the barrel, or somewhere else on the barrel. I wanted to be able to mount an optic on the end of an air rifle's barrel as an experiment, this let me try that idea. Measure your barrel well before you print anything, so you definitely get the correct width for you. I didn't have callipers so printed out a sheet with round holes of varying sizes incrementing by .5mm each time to get the diameter. This is also a good idea since your printer is likely slightly out from actual distances, therefore this would give you a good idea of what you should be printing even if callipers tell you a good number. **8x M3 x 18mm *(or longer)* screws and bolts** required. Tightly wrapped zip/cable ties will maybe do the trick however. Length of each is 50mm. If you need longer, stack them in cura and it should print perfectly. That said, if I find a need, I might upload longer ones. The files marked "_end" are specifically for the end of the barrel and have a small piece on the end to block further travel down the barrel. If you want to mount this somewhere other than the end of the barrel, use a file not marked "_end". I've included some of the CAD files in case it's of use. If you wanted to use this with a barrel width different to what I've provided, that would be the place to start. It's annoying getting the rails perfectly straight, but no harder than mounting a rifle scope traditionally. I ended up using a spirit bubble level for this. All files are available as one download - "all files.zip.stl". Download it and rename it to "all files.zip".
