The file 'Parametric Combo Scope/Laser Mount For Marlin Rifles 3D Printer Model' is (scad,stl) file type, size is 107.8KB.
I had a shitty bent rimfire scope and a shitty ebay laser sight, so I made a shitty plastic mount so I could put both of them in one place! It sucks a lot less when you think about how pointlessly expensive accessories like this are. Why would I even put a rimfire scope on a 44 magnum rifle? Because I had it, and because I can.
The design is symmetrical, so you can flip it around and have the laser on either side. If you don't want the laser, you can just omit it with a flag in the SCAD file.
This is designed to fit a 4-hole mount on Marlin leverguns (e.g. 1894/1895 pattern). This was made to fit the bolt pattern on my rifle. It's up to you to make sure the pattern matches yours. Is this the same style mount as is on your Marlin 22LR rifle? I don't know. Measure it and enter the new numbers as needed.
The receiver screws should be #8-40 fillister head. If I recall, the counterbores are sized for a 5/16" long screw, but you should verify that the depthing is appropriate for your screws. There are holes on the underside of the part where you can store the four receiver plug screws for safe keeping.
The clamp screws are all M3 cap screws.
Despite what all the wizened forum-dwellers preach as they stroke each other's beards, there isn't a single holy unified standard rimfire scope dovetail. You have to try to measure it yourself. How do you correctly measure a dovetail with rounded edges and no good datum line? I don't know. Try. Read the SCAD file, enter your best guess, print the special test part and see if it fits.
Same goes for the shitty laser. Measure it.
I mounted the scope fairly high because I wanted a quicker heads-up posture for standing shots. You can set that to whatever you want, but much shorter offsets might be problematic for the laser mount.
