After purchasing a Magnus slider I became obsessed with fidget sliders. I bought others, but never found what I was looking for. I wanted to design my own with all of the features I had been envisioning.
I’m also an inventor, I’ve received US patent for a product that I designed. I taught myself 3D design using Autocad Inventor & Fusion 360. Recently, I purchased a 3D printer to produce fidget sliders. It’s been a steep learning curve, but it’s also been very fun and interesting.
