UK Plug Cable Tidy Screwable

Designed to take an 8x1.5 countersunk woodscrew because I (literally) have a thousand of them so I can screw this to the wall beside my wall mounted battery charger in my workshop. For this use the neat notches might prove unnecessary but they're neat so I'll leave them as it keeps it multi purpose.

I grabbed the STL and added some holes and bevels in tinkercad (probably badly). Original v neat design by https://www.thingiverse.com/david_j/designs

UPDATE:
I forgot the supports but it printed acceptably (if a little scruffy I would recommend supports)
