Abacus calculation loops

Calculation loops 

I designed this for my daughter who is in first grade in elementary school. It makes it easier for her to understand math. There are 55 integrated tasks that can be solved with the help of the math loop.

For preschool or elementary school kids to learn maths.

Print Settings

• I used PETG,PLA will work, too
• 0,20mm layer heigt
• 0,4mm nozzle
• infill 15% gyroid
• no supports needed

You have to change the filament color to print the board and the numbers. See the delivered .3mf files. Its also recommended to print the board in PLA for clearer numbers and less stringing.

Bill of Materials

• No purchased parts needed
• 1x Base
• 1x each loop
• 2x each number
• 1x Board
• 55x Beads in different colors if wanted

Assembly Notes:

Simply plug everything together as shown in the picture.

You may need more strength to tuck in the loops. They should snap in place. Be careful not to break the base.
