Vernier caliper box

This is a vernier caliper box that is based on a Chinese electronic vernier caliper box but with some modifications, namely:

• The design of the box interior is adjusted to match the form of an analog (regular) caliper.
• The box uses a hinge instead of a plastic bend to keep the top and the bottom of the box together. You can use a piece of metal wire 2.5-3mm in diameter as the hinge shaft.
• There are no legs on the box bottom as the legs would complicate the printing process. Although there are little slots for the legs that can be printed separately (not included yet.)

The design is made in FreeCAD 0.20.

Update 2024-08-23: Added 310mm vernier caliper box.
