A little feedback: I found a video of this in action in the forum link, but it should be on the landing page. Also, photo examples of larger completed projects to judge accuracy are necessary. If none of your kits include the 3d parts (not the best choice IMHO), you should at least have a link to uploaded 3d files on a site where they can be ordered.
I am working on putting out more videos! Definitely aiming to address the accuracy and answer some other FAQ. As far as 3D printed parts go, tbh I'm just going that route for now because it's easier. Less hassle to deal with another manufacturer (or build out my own print farm, which is a whole other thing) and have to go through all the quality control that comes with that. Definitely planning on incorporating 3DP parts in the future, but saving that for when other stuff is more dialed in. Good idea to include a link to 3DP supplier.
