customizable ruler stop / speed marker / Linealanschlag

This ruler stop is easy to print and suitable for steel rulers with the width of 30mm and height of 1mm.
It is available in a high and a flat/smal version for narrow workpieces.

The beveled surface makes it easier to set an accurate measure on the ruler and reduces parallax error.
The little helper can be locked to the ruler by means of a nut.
A repetitively accurate measureing or marking can thus be ensured.

Required parts:

1x -> Print "ruler_stop.stl" or "ruler_stop_smal.stl"
1x -> 4mmx25mm screw for high variant or 4mmx20mm screw for smal variant
1x -> 4mm nut* or wing nut
1x -> 4mmx12mm washer

*If a normal nut is used:

1x -> Print "nut.stl" or "M4_butterfly_nut.stl" (depending on the pressure accuracy it needs a drop of glue to fix the nut permanently in the handle)
