OK, being a practical minded person (not always according to my wife!). I have collected a few guitars over the years. I bought a Hercukes 10 guitar rack. The problem is you cannot fit 10 guitars on with the temolos still fitted to the guitar. So, the solution was to design a tremolo bracket. Fusion360 again. Luckily, the design fitted all of the different them types I had. Now I can store 10 guitars and keep the trees with them. 3D printing certainly allows us to put our thoughts into practical physical applications. Otherwise, it would have probably been a cellophane alternative!
