CNC edge alignment fence for 20x20mm section

cults3d

This is just a simple project I did to make a small fence that fits on the side of the bed of my cheap Chinese CNC router. I decided to make them so that I can keep material aligned with the edge of the bed when clamping down before routing or lasering - they can be easily removed after clamping if desired. Hopefully I'll find other uses for them too :-) The OpenSCAD file is included for customisation. I included variables for the length and fence height (that's the height above the bed, not the total height). I also included a snugness factor variable that can be adjusted to make the finished model fit snuggly in the 20x20mm extruded-section slots. And if you're interested you can also read my blog-post about this project at the link below. https://cncmakerzone.co.uk/cnc-bed-edge-fence-made-with-a-3d-printer
