This is a compliment to the vertically oriented caliper and ruler module, trading off a lower profile for a larger footprint. Features slots for 12 spare LR44 batteries and the battery compartment screwdriver.

The FreeCAD model is included, with all the caliper dimensions in a spreadsheet. If your calipers don't match my settings, just adjust the dimensions.

Can be printed without supports.

The most important thing is to make sure your magnets have the same orientation throughout the whole system.

More about the FreeGrid system and other FreeCAD tools to build your own modules is available on our FreeGrid page.
