This is a design for a school use educational aid. It is a clock assembly to teach reading time. Units like this can be found on amazon for ~$10. The clock I designed has slots that the students can fill in themselves, adding to the teaching ability for both the hours and minutes of the clock. Based on a print time of 4 hours 24 minutes and 79g of PLA filament this clcok costs $1.66 to produce, a 83.4% cost savings. Number coins can have number cut puts colored with marker to add contrast for easy veiwing. Hands simply press fit onto center collapsable joint as seen in assembled picture.    Link to commercial product https://www.amazon.com/Learning-Resources-Time-Student-Clock/dp/B00000JH41/ref=zgbs25220340113?encoding=UTF8&psc=1&refRID=HFZE5GA0K52TRKKQ132N
