Better MK4 2Kg Spool Holder

MK4 2Kg Spool Holder with increased strength in the clamp area.

The original design contained seams and internal voids in the lower clamp area See last photo.

My first print of the original design cracked in the lower clamp area. I strengthened these areas to improve durability. See third and fourth photos.

Added three internal slabs the clamp area in the top, bottom, and rear of the clamp area. Restricted seam locations in the lower end of the clamp.

Third photo illustrates the original design lower clamp area showing internal voids and seam location along a 90-degree bend.
