25cm Ruler

It's a simple ruler, 2mm thick
Notches have 0.2mm thickness,

Versions:

• Diagonal version has notches on diagonal, good for Resin (DLP/LCD/SLA) prints.

• Horisontal version has 2 horisontal levels, good for FDM prints
  

FDM settings:

• Nozzle: 0.2mm or 0.4 (but then notches will be less clear)

• Material: any, Personally printed in PLA

• Ironing: topmost surfaces (I use 12% flow on my bambulab p1s)

• Orientation: lines should be aligned with longer side, so it's not breaking on walls/layers

• Layer height: for diagonal use as small as possible, for straight 0.2

• Multimaterial: up to you, maybe will put colored 3mf here later

Knows Issues:

•  Diagonal version is bumpy, will shorten lines, so it doesn't affect straight lines the ruler
