This is a set of drawe designed to fit into an Ikea Billy bookcase, cut from 3mm HDF/MDF using a laser cutter. The drawe themselves have an internal space of 71x102x28mm, and has a total of 72 drawe. I have included an opeCAD script to generate internal partitio for the drawe as required, and also included an STL of an iert for three partitio. These were designed for organising my electronic components, but I guess they would be good for lots of craft stuff. The frame itself needs to be held square whilst gluing together, and I printed some brackets, 'glue '. I used superglue to glue the drawe together as it was quick and easy.
