A4 paper cutter frame

Frames for cutting A4 paper (21cm x 28.7cm, or 8,3 x 11.7 inches) in different sizes, useful to create square sheets of paper for origami.

The frame keeps the paper sheet steady while you cut it with a paper cutter following the slids in the model. The corners of the frame have holes in them, so that you can better align the sheet inside the frame.

The slids of the frame allow to cut slices of
* 10.5cm (half the width of the paper sheet)
* 8.7cm (the remainder of the sheet would then be a 21cm x 21cm square)
* 7 cm (one third of the width of the paper sheet)
* 5.25 cm (one fourth of the width of the paper sheet)
