Parametric Dial Indicator mounting bracket for Prusa I3 clones

thingiverse

I wanted to create a dial indicator for bed leveling and couldn't find an existing design that fit my Prusa clone (an Afinibot A3), so I made a fully parametric version in OpenSCAD which should be easily adaptable to any printer resembling the Prusa I3. I have included a sample STL file for the bracket shown in the photos, but most users will need to generate their own using the .scad file. There are many customizable values, but most of them work at their default settings. The three values that most users will need to set are: - rod_diameter (the width of your X-axis support rods) - rod_c2c (the spacing of the X-axis support rods) - mount_height (the height of the mounting tab on your dial indicator) You will also need a single machine screw, nut and at least one washer for proper assembly (see photos). With the screw properly tightened (and the load on the PLA spread out by a washer) I was able to achieve repeatability within 0.001" when removing and replacing the dial indicator on my printer's X-axis rods. Results may vary. The bracket can be assembled and used either way up, depending on what you find most convenient.
