Miter Box Cutting Aid 90 - 45 - 22.5 Degrees

I was looking for a miter box to cut window strips with my Japanese saw,

but I couldn't find one that was designed for very thin saw blades.

I quickly drew one; it's for strips approximately 35 mm high and 40 mm wide/deep.

The Japanese saw I use has a cutting width of approx. 0.6 mm; the slots in the miter box are also 0.6 mm.

The miter box has slots for 90 + 45 + 22.5 degrees.

It is also relatively stable, hence about 3 hours of printing time.
