Summary

I liked the design ot White_Panters ruler stop. But as my ruler was realy thin with only 0,75 mm his design just did not clamp it.

So I redesigned it from scratch in SolidWorks, while copying his style. I also upgraded to a bigger screw and put the nut in the bottom. So you can now tighten the screw by hand, even without a cap.

This actual 3MF-File is for a ruler 24.6 mm x 0.75 mm. Even without the screw it clamps nicely.

SolidWorks-File is included, so you can configure the part to your specific ruler. Or you may ask me to make a specific version.

I just added a cap, which is to be pressed on the head of a standard M5 hex head. Such a head should have a diameter of about 8.4 mm.

You need:

• M5 x 20 hex socket Screw
• M5 Nut ot be pressed in the bottom
• Washer 10x1 mm to be pressed in on top

Printing setup

• Print it with the flat side on the printer bed. No support needed.
• I reccomend using raft, as I had several failures with the smal lip when trying without.
• Layer hight 0.2
• at least 3 perimeters/shells
• low infill (10%)

for the cap

Orient the hole on the bed. It is designed to be printed with the hollow insided. So you will get a nice finished top.

• Do not use support
• print with raft.
• Layer hight 0.2
• 5 perimeters/shells
• print with PETG, so it will be somewhat elastic for the pressfit. PLA might crack.
