About this 3D model

This is used to level the HBP on a Makerbot Replicator. Holds a Power fist 2.25" Deflection Gauge (.375" center mount) & 4 Rare earth magnets (8mmx3mm). Both are available from Princess Auto in Canada Gauge #2970986 - $18.99 & Magnets #8183915 - $2.49. When fully inserted there's only about 2.5mm pressure on the gauge spring, so the HBP does not deflect.
