Summary

It is not recommended to place the handle part vertically because the strength between the layers is poor, and the hand saw happens to have a large force between the layers, which may cause cracking, as shown in Figure 3.

If your printer is large enough (diagonal length greater than 240mm), you can choose to print a whole at a time.
I also provide a discrete version of the model, using M4x16mm screws for the connection of the main body and sawbow .
The connection between the cover plate and the main body uses M4x10 screws.
