Addon-hacks for Printrbot CNC Beta 01

For this machine: http://printrbot.com/shop/printrbot-cnc-beta-01/

  • cnd-handle.scad : Taking the finger-pain out of carrying around cutting edge technology :)
  • y-endstop-trigger.scad : For a modification that mounts the y-endswitches under the moving tray, these are the stationary triggers mounted on the rail.
  • x-switch-spacer.scad : The default mount of the switches on the x-axis is too low so that they are not triggered reliably. These standoffs, mounted under th switches fixes it.
  • spindle-holder.scad: Mount of a spindle. This helps to mount a spindle in the screw mounts of the CNC; the spindle itself is held with a hose clamp. The top part needs to have slots cut with a saw (printing them makes stuff too fragile), see image.
