This project is a mechanical counter. They work in such a way that you can count from 1 to 59 without any risk of getting it wrong. It's easy to use: just turn the left-hand crank and the numbers will scroll past at your leisure. This tool is small ((H8,W5,D3,83)centimetres), so it can fit in a handbag, cargo trouser pocket, etc. All the 3D models of the components have been modelled using Fusion 360 software. If you wish to reproduce this counter, a PDF file is available to help you build it if you download this project.
For this production we used two components: wood and PLA (polylactic acid). For the box we used 3mm-thick limewood shaped with a laser cutter. For the PLA components we used only Ultimaker printers with precision 0.4mm threads. Of course, this production can also be made on other printers.
