Hi there,
This is Bogdan from Romania. I'm a mechanical engineer specialized in the industrial robotic field, 3d designer, modeler and prototyper.
I have some experience designing sex toys, and I really could help, but is necessary to have more info.
What kind of toy? for man or women? and from here a lot of other questions...
as you probably know, my boyd and crave already have bt controlled vibrators. also a lot of other producers made advancements creating apps to pair with the toys.
ovo has very interesting products, and Cal Exotic come with full range.
if you want to discuss more, you may open a chat board here and beside you'll clarify what kind of sex toy is required, I could give you some indications.
Based on your input (ideas/sketches/drawings/models/references, etc) I'll make a primal model. On this model, we'll adjust/modify/change what's necessary to achieve the desired shape and functionality.
Once the final model is approved, I'll send you all the files required for manufacturing.
