Heatbed Cable 90 Degrees - Bambu A1

Remix of the Bambulab A1 – 90° Heatbed cable by Anri.

Two changes:

1 - Reduced length of holder where cable comes out to reduce cable strain

2 - added interfaces for snapping top down so you don't need the cable wrap to keep it together

My main goal of preventing the printhead from contacting the heatbed cable is accomplished. This version makes the cable about 1" closer to the wall vs Anri's version; so it isn't as snug a fit with the wall if you are trying to minimize distance to the wall and the heatbed cable, but still pretty good.
