Drill bit holder magazine

My [cordless drill](https://www.craftsman.com/products/craftsman-c3-19-2v-lithium-ion-hammer-drill-kit) has a slot to hold a drill bit on either side. This slides into those slots to hold 6 drill bits per side. In the sketchup model the size is correct, but when I actually printed I had to scale up 6% for everything to fit.

I printed with no supports or rafts, 33% infill, .12mm layer height on an Ultimaker 2+. Can be mirrored to go on the other side of a drill.
