I love gridfinity but for more volume it takes much time and material. So i designed this fast print drawer separator which i use to get my ikea boxes more organized.
For the start I uploaded 100mm high parts with lengths from 40 to 248mm in steps of 8mm. They can easily be stacked together and re-arranged any time.
There is also a connector to connect 2 piecs to a even longer one. More connectors will follow soon.
Print speeds for width 248mm x height 100mm (all with 0.4 nozzle):
Let me know if you need higher or lower versions.
