This started out as
Bed Leveling Attachments by by maker311
But the clips didn't work on my print head by virtue of the side fan, and custom duct. So I created a single object to hold the leveler in place, and allow me to slide it around on the rails (on the magnets) freely. Further, when you begin leveling on the Powerspec, the head goes home which makes clipping the leveler in place only possible after the head has gone to the first position.
I use a rubber band to firmly hold the level in the mount, and it is very accurate, and very easy to level the bed now.
I printed it on raft, and with supports, which Simplify3D does extremely well, very easy to remove.
Very happy with it, and thanks to maker311 for the original design.
