Math Learning Wrapup

An OpenSCAD file to create customizable learning wrap-ups. Support for addition and multiplication is included.

Wrap-ups are learning tools for children. This set specifically helps train addition and multiplication. When printed out, attach a long, thin string to the empty hole. Starting at the top left notch, move the string over to the corresponding solution on the right. Then, return the string along the back to the following notch and repeat until you reach the end. Once finished, turn the wrap-up over. If the solutions are correct, the string will match the answer key impressed upon the backside.

Included are a pair of example stls, for the 9* table and the 10+ table. However, any small-ish integer number will also work(fractions and decimals are not implemented), for both addition and multiplication.

These can each be printed off for about 30g of material each, which at a $25/kg for PLA amount to about $7.5 for a set of 10.

Comparable product can be found for about $
