Allen Key T-handle holder

I needed a better way to hold hem when using my allen hex keys. Stumbeled on these, all credits go to Uncle Frank says for designing the handles.

Had a Skadis board but no holder for the printed handles. So I “designed” one. I only have basic drawing skills on Tinkercad. So its possibble that I have made a few mistakes. 

It holds the 1.5, 2, 2.5, 3 and 4 mm handles.
Printed in pla, without support but with a brim just to be sure that the hooks at the back don't come off when printing. 
Bridging at the top of the model is no problem without support.
