OVERHEAT SHOULDER PIECES

This is a 1:1 replacement for a certain MP scaled yellow racecar robot's LEFT and RIGHT shoulders.  Original fails due mostly due to poor molding processes and thin sections not filling during molding.   There are no design improvements, just a printed piece replacing a poorly molded one.  This is available in what i  think is the best material avaialble for this print(PA12 via multijet fusion process).  It can be done cheaper in the Versatile plastic but the multi jet fusion product better and has better durability.  Overtighten slightly or misalign and tighten the Versatile plastic piece and it will crack/tear just like the original.  Yes yellow is available but i just don't recommend the regular versatile plastic, unless you don't plan on tightening the upper screw at all.  In short if you really want it , its there but if it were me i'd get the black PA12 multijet fusion product.
I've  tested  both the right and left right shoulders from the the expensive single up and also a 4 up version.  They both work well and have survived a lot of posing in robot mode and so far minimally 4X transformations (back and forth twice). This is a 20 up version (10 lefts and 10 rights) and quality should be the same as the 4 up (just a longer tree).  There was no downgrade in quality going from 1 to 4 but you will need to snip or cut the parts off the tree.  The 20 up should be the same but much cheaper per part.
