This wall mount drillbit holder angles the bits so that a number of similar holders can be mounted above or below for organisation.
For samller bits up to 3mm the holder has space for 3 bits. The assembly can be printed top surface dow for the best visibility of text showing sizes. Single wall printing on the first layer seems to give the best text definition. I recommend using contrasting filament colours for the best effect. 4 half inch screw is plenty adequate to hang the holder.
