#TidyDesk- Through the use of belts and simple gearing, the sandcastle supply holder rotates as one rotates the handle. Multiple bearings allow smooth rotations. Spacers and screws make sure that the durability of this model isn't a problem. Multiple layers add a lot of space! The main feedback from v1 was that it was bland and it lacked other functionalities. I added a brick texture to the main body and added 2 Post-it notes holder on the side! Look at SandCaslteRevolverv3 for the most recent model!
