Thanks to J White and Whity for their models. I used them to get a box that packs away easy and keeps everything organized. With the added bit slots and tool brace on the top side nothing rattles around in the box.
I printed with PETG, used supports and a brim to keep everything flat and stuck. The slots for the bits are a little tight but fit. Most of the Parametric boxes use M3 bolts but the ones I had around the studio were not long enough so I used some .125" steel rod, worked pretty well.
The author remixed this model.
I added holders for the extra bits to keep them all in one place, resized the the parametric box to fit tools and holder.
