Unifix Perkins Brailler Cube finger garage

Help with learning BrailleThis object was created in Tinkercad. Modify it online https://www.tinkercad.com/things/lhR8YslM9tgThis is a simple shape created from an idea shared by another assistive technology specialist who used tape and hollow cubes purchased online to make "finger garages" for blind students to hold their fingers in place while they learn to use Perkins Brailler machines. The cubes simply slide over the keys instead of being glued or taped, and can be easily removed.They are printed with PLA or PETG. I've used 100% fill and default layer height. You may need to adjust for best results. My print temperatures are 215c for PLA and 230c for PETG and 80c for bed temperature for my filaments.
