Add this to any ruler to make a rigid T-square. Add a 3mm screw to clamp it your existing ruler, no modifications required.
It's a multi-piece design using a TPU/TPE tab for grip on the ruler, along with a foot insert to distribute the pressure. The screw and beveled edges keep it in place. PLA or PETG will work fine.
The screw length will have to be at least the wall thickness + nut size + 1.5mm. An 8mm screw glued into any knurled nut out there will do perfectly.
You can edit the design to make a regular 90-degree square as well.
The included STLs are for my 51mm (2") and 32mm metal rulers. If you don't have Fusion 360 I can make some common sizes if people request it.
Print as in the STLs - The square prints vertically, the inserts are flat. Use of a brim or at least anchor dots at tne end is recommended to prevent warping.
Any infill and layer height will do.
It's fully customizable in the parameters of the Fusion 360 file. I recommend keeping the wall thickness all around to at least 2mm. Be sure to leave some room (0.2 to 0.5mm) around the ruler to allow it to slide.
One quirk in F360 is with the screw hole - The parameter only changes the diameter, not the screw thread. You'll need to edit the screw function if you don't want 3mm.
