A redesign of Timebomb's rulers, using dual extrusion to make it more sturdy. The original version with numbers being cut outs all the way through was very weak for my tastes - my first set broke trying to remove them from the print bed.
These will be solid plastic, and I personally used a higher infill than I normally do just to reinforce it further.
This also includes a full length ruler for long range/movement 5. That way you have a set of matching rulers without needing to pass around the cardboard stick for the longest range.
