In short this was designed to give me options for Length of Pull for my CZ457 Pro Varmint with the Boyds wood stock.
There are 3 models, 25mm, 20mm and 15mm
The fit is not perfect around the edges but I got it close. Once mounted it is solid as a rock.
When time allows I will try to get it closer to the stock size and contours.
I printed 3 perimeters using carbon infused PLA. 20% infill.
The author marked this model as their own original creation.
