Raise3D Pro2 Bed Leveling Assistant

This print will allow you to mount a Harbor Freight Digital Indicator to the front extruder fan while still allowing it to work. It's up to you whether you want to take it off or leave it after leveling. I tend to just remove the indicator.

With the indicator mounted and motors off, start moving it around and level till you cry cause you find out how warped the bed is.

I separated all the model bodies to avoid wasting plastic on support creation.
After printing, lay flat glue the pins to the base, then once dry, glue the base to the Indicator mount.

Remove the metal fan guard and reuse the four screws.

I used a sleeve and a screw to attach the indicator to the mount but you can use anything laying around or pay Home Depot a visit and find the small screw bins.

Good luck and hope it helps with your printing needs.
