Stacy, thanks for your efforts. I know you're just starting off and wish you much success...but, the pricing for a 3D-printed item does seem a bit steep, even after reading your pricing justification at your website.
If the item was injection-molded and didn't have that "unfinished" 3D-printed look, I might be tempted at that price, because it's a great idea and fills a need. Just as a personal opinion, but I think a price closer to $35-50 range for the 3D-printed product would generate far more business for you. If you ever went to injection molding, a higher price might be justified in the minds of most.
That said, you seem to be the quintessential American entrepreneur and know you will do well in the endeavor - congratulations!
