About this 3D model
Summary This is a dual picatinny rail mount for the Crosman 2240. The model requires a little bit of sanding to make a snug fit. I used some 400 grit sandpaper wrapped around a rod and slightly sanded the inside of both holes. I also added four holes for brass M3 inserts. These can be melted in with a soldering iron. And I screwed in four grub screws. It may not be necessary when you already have a very tight fit. The model is printed in PLA/PHA. No support material is needed. Model must be printed straight up. *Edit: Made a slight change to the model. Chamfered the edges and added an insert for a name plate. See picture. Added a dummy name plate as a reference. Reprinted in Woodfill and stained it. Print Settings Rafts: No Supports: No Resolution: .2 Infill: 20%
