Mathbox - Mathematic basics practicing
I made a first version for my 7 years old granddaughter to practice basic operations (+ and -) of mathematics. His father place the numbers to add or subtract and she mentally calculate and give the answer.
They use this first version since couple of weeks.
I have reworked this Matchbox to make it more versatile.
Mounting instructions :
- Turn the box to view the rear
- Insert the hex Axis from the left of the box
- Insert on the axis, Spacer_D, wheel, spacer_B&C, wheel, spacer_B&C, wheel, spacer A.
- Pull the axis all through and screw on the right
- Insert the clics stoppers in TPU on the top 3 holes, glue them if necessary
- Insert the operators from the top
