cable tunnel for enclosure, for plate thickness 8-9mm

An easily remouvable cable tunnel for my self made enclosure. Fits a plate of a thickness of 8-9mm.

Draw a line of a length of 50 mm, then drill a hole of 15 mm on one endpoint. With a router make a 8mm large mortise with the second mark as an endpoint.  

Or use one of the templates. 

Then pass the cables and put the tunnel in.

I added a one-piece model, which works well, if you've centered the mortise precisely at the  line. It looks nicer, but is perhaps more difficult to remove. If not perfectly aligned, take the two piece model.

Added two templates to make it more easy to do the cutout. 

One in original size of the hole that you can glue on the surface with double sided tape and do the cutout with every tool you like. The other one for use with a router, a router bit of 6 mm and a bushing guide of 12mm. Should give the best result.

Based on the drawing I added it should be easy to create your own template if you don't have this combination of router bit and bushing.

Printed in PETG, 0.2mm layer height, infill ~ 15%, 3 perimeters

The little gap between the two parts of the two-part model is intentional.

Why it is that complicated: I needed a hole of 15 mm to pass the ferrit core of the usb cable connecting the raspi with the printer plus the space for the other cables.
