Singapur method equivalent fractions

My son was required to have this set of equivalent fractions for his math class and of course I wouldn't spend THAT MUCH money buying this thing if I could spend THAT SAME MUCH money buying different PLA colors for printing them myself. So I spent an enjoyable couple of days designing this pieces and then little more than a week printing.

Indications: multiply the pieces in Cura or you favorite slicer, don't forget to grid arrange them. Print them with raft.

The pieces are designed to print vertically without support.

Included fractions:

* 1

* 1/4
* 1/5
* 1/6
* 1/8
