Add a printable SnapLine desk cable manager

[devbadya]

Six snap-in slots as a Bambu Studio project so the part lands on the Prepare plate ready to slice.

What this is

A desk cable comb (80.6 × 28.0 × 15.6 mm) for USB-C through laptop-PSU jackets. Cables click in from the top. The .3mf has two objects: the body and raised size labels, so an H2C can print the numbers in a second colour without an AMS.
