Basic Protractor

thingiverse

As a middle school math teacher, kids often struggle with finishing their homework at home due to a lack of necessary tools, prompting me to develop a solution. Occasionally, borrowed materials fail to be returned, resulting in frustration and wasted resources. I devised a plan to create a fundamental protractor that could be printed on demand, reducing the need for store-bought versions and preventing ongoing losses. The file I designed can print out a compact protractor measuring ten centimeters wide, saving space while remaining effective. By substituting numbers with markers at every ten degrees interval, the printing process is significantly accelerated.
