I like the design. For those who don’t have access to a 3D printer, this is a great offering. Price wise it is about market rate. You have to make a profit while keeping the price down. It is a tough balance to keep.
From a marketing perspective, will it be available for different numbers of razors? I rotate three razors, so a holder with any more than that becomes a waste of counter space for me unless I can also hold a couple of brushes knot down. As currently designed, the slots are too narrow for a brush, so that wouldn't work.
Is your plan to offer different sizes? I guess that would be practical if you can 3D print after receiving an order, than you don't have inventory holding costs.
How about an I-beam design, where one side is cut for razors and the other side is cut for holding brushes knot down?
I like the design but it being 3D printed it makes it look like something that should be sold at a Dollar Store. Maybe if you were thinking of it being injection molded and a smoother look it might be something I would consider but even then not at that price tag. It would have to be made of wood for a nicer look for me to spend that kind of money one something to hold razors.
If you could get it cast it in bronze, you would have an heirloom quality stand that is able to shrug off water and soap, and has a strong maritime link.
You asked for honest... I think the 3D printed stand smacks of profiting off the reputation you have built, which is often the harbinger of the downfall of a reputable brand. Sail with care @Captain Pre-Capsize ... here be sea monsters.
