A simple wedge that can be used when loading and unloading a barbell. Save your strength for lifting, not loading.
Fits standard bumper plates and has been tested without failure at 495 lbs (max I could fit on the bar at my gym).
Technical
Printed on MOST Delta 3D Printer: http://www.appropedia.org/Athena_Build_Overview
I used OpenSCAD to design the part. There is an engraving at the top of the wedge that can easily be adjusted in the code. The ramp of the wedge tends to peel upwards; HIGHLY recommend adding a raft to increase platform adhesion.
Note the wedge uses the full width of the MOST Delta printer.
