ER32 collet holder

In order to store my set of ER32 collets, I couldn't find a support that met my requirements, so I decided to draw it in fusion 360.
I recommend choosing a non-smearing colour, so I chose PLA, which is enough stronger and will chemically accept the residual oil on the collets. I decided to make two supports rather than one to hold all the ER32 collets set, so that they could be placed side by side or one on top of the other.
