The Roller Ruler 8" model is designed for efficiency and enhanced movement across various surfaces. Its structure allows for optimal rolling mechanics in various mechanical applications.

*NOTE: There are 1/16" markings for every hole. (Not seen in the Cover Image)

Required Parts: 2x 608zz bearings

Printing Recommendations:

• PLA, PETG or ABS

• Ensure a minimum of 15% infill and a layer height of 0.1-0.2mm for precision (the markings are close together). 
   

  • I used a 0.2mm nozzle.

  
   

• Print Marking side down to avoid use of supports
