Didn't like any of the two piece chassis for the TX22 so I designed this one. It assembles easily and removes easily. This is the first "beta" release. I may put .stp files up later after this gets more testing and proves out.
Comment with any issues or suggestions. I'm keeping a list of improvements and additions and will make updates at some point one it gets some good testing.
Other accessories in the pictures are the @db-firearms "DA Brace for the DB Alloy". It won't work as-is and I had to modify it to fit a regular rear mounting rail. I may upload the modified version at some point. https://odysee.com/@db-firearms:4/DA-Brace-1.0:d
The flash can is the @FFFTech "Rimfire Redirectinator 9000". Helps if you don't want to risk blowing your fingers off. https://odysee.com/@FFFTech:3/Rimfire-Redirectinator-9000:0
*Updates*
-3/30/2026: Fixed scaling issue with .stl files. They should now come in at proper scale when dropped into a slicer.
-4/3/2026: Added "Chassis - Extended" version STL and directions info for it. Added for weighted back plates use.
-4/7/2026: Adjusted top surface of Hand Stop Pic Rail and Hand Stop Pic Rail - Mag Holder that goes against the Chassis Rail Clip. It was too tight for the accessories to slide onto the rail.
Adjusted Rail Lock Teeth Thickness. To improve fitment and prevent possible snagging.
Adjusted opening of Locking Clip.
