Ruler Marking Guide

12-Aug-2022: Added a 28mm width version. Same applies to widen the slot if necessary by filing/sanding.

31-July-2022: Based on jsk-koubou Ruler-Marking Gauge, modelled this into CAD for printing, added a small printed block to act as holding the ruler once length is set.

Ruler to be used is 26mm width with 1mm thickness.

Requires
1) 5x M3 heat inserts (Length 4mm, OD 5mm)
2) 4x M3x12mm Socket head screw
3) 1x M3x8mm Socket head screw or better, use a M3x8mm thumb screw

Please scale accordingly if there are shrinkage for your filament.
Print as per orientation.

You might need to widen the slot for the ruler by filing, if it's too tight fit or small accordingly, making sure it's filed straight.

Enjoy and comments are welcome.
