Zen Garden with Crank Handle

I got my inspiration from JustBaselmans thinking “Huh, what if I could turn that with a crank?" This was an educational project to me as I'm still learning the ins and outs of Onshape. It's not elegant, it's far from perfect, but I made it work and it's kind of relaxing. Printed in PLA. Use very fine sand if possible. Please tell me if tolerances are too tight. I tested everything on my Prusa. 📷 Image redacted — claim this model to add your own media Assembly Glue the crank parts together. Glueing the crank and the gear to the handle is optional but recommended. I had to sand the seam on the handle a little bit down as it caused some weird friction. Assemble as shown in the picture. 📷 Image redacted — claim this model to add your own media (Beware: This shows the gears in motion but a prototype is shown) 📷 Image redacted — claim this model to add your own media
