Caliper Practice Block

This block is a tool I use in my middle school classroom. We use it to practice Vernier caliper skills after the students have learned how to use them with other objects. You can use it as a performance assessment--you can print blocks that are scaled differently to make it impossible to copy at the same table.

For example: if you have six tables, with four students each, you can print out six blue blocks at 75% scale, 6 red blocks at 100% and so on so each student gets a block with different dimensions.

It allows the use of all of the tools on the caliper--depth of hole, outside and inside diameters, step height as well as the lenth, width and depth of the block.

The prints you see are printed with an Ultimaker 2+.
