I have created this  part to facilitate cutting plywood, with the following features:

  • turns a steel ruler into a square, gauging rule.
  • fully parametric.
  • prints without supports, check orientation sample.
  • sample provides fits Jula steel rulers.
  • it does not require additional hardware to lock the position.
  • has a clear interface for the desired cutting measurement

Your printer will need to be able to bridge the width of the ruler. Please ensure that the slicer is resolving the bridge properly. Check attached sample.

The dimensions of the ruler need to be adjusted so that the ruler locks in the part. It has to be possible to slide the ruler to the desire measurement but it has to lock the measurement. It is not difficult to find the right balance. Just measure your ruler with a caliper and start by adjusting tight tolerances of around 0.1 or 0.15 mm. Use a short TotalLength measurement (i.e. 70mm) when printing tests. 

Access the model in OnShape and customize it for your ruler, see attached instructions.
