Wow, sorry to tell you this but manfredvr blatantly copied the engineering and look of the Perfect Effect Mixmaster addon from PC-06. Certain details in the bumber, grill, windows, mirror positioning, even details on the sidedoors indicate this is a direct unlicensed rip-off of Perfect Effect and I wouldn't sell this if I were you.

Nothing against your 3D printing skills but I would highly recommend PC-06 as a painted, polished, injection-molded, finished add on kit, even at $50 (which comes with other Devastator parts like shoulder, arms, cranes, hands, etc.) versus someone who stole the design and leaves a 3D printed texture and painting to do.
The new version of PC-06 fixes the floppy wrists too.
