Mô hình đồng hồ analog giáo dục (Analog Teaching Clock)

This model includes two versions of an analog clock with moving hands. One clock has a standard face with digits and minute ticks. The other has digits and minute ticks, plus time phrases every 15 minutes (e.g., "top of the hour," "quarter after," etc.). I designed this to teach time words to beginning adult English language learners, but they could be used for children as well.

All parts printed in PLA, 0.28mm layer height, and 10% gyroid infill. Clock face and hands can be printed with no supports. The center peg works best when printed on its side, with tree supports. This ensures the layer lines are perpendicular to the force applied when inserting the peg and holding the hands firmly. Numbers, minute ticks, word phrases, and the outer border can be printed in a different color by changing filament at layer height. Filament shown in photos is Inland white, Inland blue, and Eryone green.

This model was inspired by EduClock - The Education Clock by Handy Handicrafts. I redesigned the entire model from scratch, using Tinkercad. I wanted the hands to be a bit thicker and the peg to be a bit easier to insert without scaling up or down. I also need the design practice.
