Random Calculate Equation Generator
Description
Hello fellow 3D Print fans. Teaching my kids to calculate, we use to sit an "build" the random equations on paper, using a 10-sided dice. Instead i have now designed a "Random Calculate Equation Generator" You just chose how long you want the equation to be and what it must/can contain, and then spin the wheels. There is a "0123456789" wheel, just print as many you need of the same wheel. There are also some +,-,X, DIV wheels. And also a "." wheel if you want to get in to the trouble of "decimal places". It is made to be printed in one go at my two color Ultimaker printer. But i also made two "empty wheels", if you want to print the wheels in only one color, and then write on them using a maker pen or put on stickers. You can also print "only the number/sign wheels" in one color and numbers/ signs are embossed, and can be read anyway. I just printed my wheels in "metal" PLA, but i made the axel and clip in ABS for extra strength. Wheels are about Ø40mm. But they are easy to scale up or down, if you want. Dealing with kids i did not like small parts. So i designed axel and lock clip to be a little more big, than "what could have done the job". A nice and little, easy to use tool, where the kid can make his/her own equations to figure out.
