I modified the bottom rear corners pieces for the Prusa Lack enclosure to accomplish 2 things:
Save about 2 inches on power cable length. The original bottom corner piece has the cable cutout oriented towards the rear and wastes cable length. By moving the cable cutout towards the front I was able to avoid lengthening the power cable on the MK3. (Left version in thumbnail.)
- Mirror the cable cutout to allow running cables out the side or the rear.
Either of these corner pieces can be used to replace both left and right bottom rear corner pieces in case you want to add more stuff in the future.
Use of the 2-way locating cone is optional as the original can just be turned to whatever angle you need.
Parts were modified using OpenSCAD. Imported the original corner pieces and mirrored along a 45 degree plane. Intersected the mirrored copy with an unmirrored copy.
