A handle to push and pull the print-bed of your printer so you don't have to touch the hot part. Use exterior mounting tape to attach the handle to the y-axis carriage.

The handle is 10 mm tall plus the thickness of the mounting tape. You can scale it if that is too tall for your printer. The picture shows it installed on a Monoprice Maker Select v2 (Wanhao Duplicator i3 V2).

This handle won't fit the Duplicator i3 V2.1 because of a ridge on the carriage. Try Mechman's bed handle (http://www.thingiverse.com/thing:1968830) if your printer is a V2.1.
