Allen key holders for the workshop. Both metric and imperial.
They are a nice fit with 0.30mm clearance added to each size.
I printed different colours for the font so it would stand out. Due to the size of the holder the font is a little small but still easy to read.
The screw holes are 6mm ID.
Print in any material you like. I orientated these with just like you would install them. No supports needed.
