Low Profile Cable Anchor for 8mm T-slot (Prusa)

In Chapter 8, step 22 of the Prusa i3 MK3 instructions (https://manual.prusa3d.com/Guide/8.+Electronics+assembly+(B7-R3+design)/823?lang=en) the resulting cable bundle was large enough that it still touched the table when the printer was righted. Fearing the insulation would wear away with vibration, I designed this wide, flat cable anchor to use the 8mm T-slot to keep things tight.
