Don't know what to do with all of those flow calibration cubes? Print this assortment box to give these cubes a second life.

I have lots of different filaments and since i mostly print technical stuff, flow calibration of all of these filaments is a must when a (tight) fit is required. But what to do with all those calibration cubes? Well, since i also have lots of small things laying around my work space, like screws, springs, electronic components, etc, let's make an assortment box that fits 3x6 of those flow calibration cubes.

The cube i use to calibrate my flow rate is 30x30x30mm. I print these in vase mode, single wall. This assortment box holds 18 of these cubes. That gives 18 placeholders for screws, nut and bolts and the like.

Printing:

Both parts are printed with 0.45mm line width, 2 perimeters and 3 top and bottom layers at a layer height of 0.2mm. No need for supports, brim etc.
