Manual Saw jig for angle cutting.

you can modify the parameter on the spreadsheet inside the freecad file.

the stl file parameter:
Inner gap (wood width) = 30 mm
Jig Length = 100 mm
Jig Height = 60 mm
base height = 3 mm
wall width = 2 mm
saw gap = 2 mm

I'm just learning parametric design, any suggestion are welcome
