I am moving some of my products from my Shapeways shops over to Panzer Concepts including many of my Sherman related products. Lately customers have been having problems with some of my products being suddenly unable to be printed by Shapeways and Panzer Concepts deals only in scale models were as Shapeways is more interested in trinkets, toys, etc. Panzer Concepts does a wonderful set of clickable Sherman tracks with extended end connectors and I wanted to consolidate my products to make it easier for the modeler to find.
