Fish Ruler Upgrade

This is an upgrade from my other ruler. I made this on my Neptune 3 Pro so I cut the ruler in half because it was to long for the plateso I made the little sleeve for it you might need to make the sleeve a little bit bigger or just give it a light sand to smooth it out so both sides just slide in. Layer height 0.2 Wall count 2 15% Infill. All parts are made with PETG PRO. As I only have one extruder I put in a pause at height at layer 21.
