This is a custom adjustable back shaft for a Umarex Morph 3X.
Since my scope was a little to high, I designed this part, to fit on the original back shaft.
You may have to file/sand the inner of the original shaft, since there are some plastik molding things left, which block the mounting parts.
You have to print part 1 and 2 (Teil1, Teil 2) 2 times and the main part only 1 time of course.
I printed it with 100% infill, to add a little weight to the morph.
For the mounting you´ll need:
8x M3x30mm Screw
8x M3 Nut (optional since the fit is pretty tight)
2x M4x45 Screw
2x M4 Nut
4x M4/M5 Washer (bigger diameter)
