3D printed mechanical 7-segment digital clock
Mechanical 7-segment digital clock driven by only one RC servo motor. All segments and carries (10, 60 minutes and 12 hours) are mechanically resolved. 3D data and codes are available at https://www.thingiverse.com/thing:4626956 It consists of 54 types, 115 parts printable with common 3D printers. You also need - 1 RC servo motor (normal size) - 1 micro:bit and 5V power supply (break-out board, etc.) - 7 rubber bands - 15 M3 bolts - paint (ex. white for black 3D printer material) Necessary tools - sand paper or file for deburring - soldering iron for welding plastic (see https://www.youtube.com/watch?v=qPNacMCvSvQ ) - M3 screw tap (if you do not use tapping screw) - Silicone grease or spray for lubrication My works on digital fabrication: https://shiura.com/dfab/index-en.html Please subscribe my YouTube channel if you like!
