We found a remake from our project Make your own 1952 Fraction-of-an-inch Adding Machine on display at Xerocraft, a hackerspace in Tucson. They cut and engraved the calculator out of hardboard using their laser cutter. It’s sturdier than papercraft and it looks great!
I made this! Thanks for checking it out. My husband, who is an aircraft mechanic, has one in his toolbox now.
