I don't have any issue with sharing my design ideas, but currently I don't plan to share the actual models that I create. The image file along with the actual PMag is enough for anyone with 3d modelling experience to recreate my work, and there are online services that will print your creations (on much nicer hardware than I have). I've invested time in the printer and design effort that has some value that I want the option of recuperating. I consider this the same as someone posting photos of a fiberglass part that they've made, versus supplying molds and actual parts.
