Instructions

This model requires pausing the print for inserting three steel washers for weight. An alternative design not requiring washers is posted here. You will need to pause your script at the right time to insert the washers. Once you have inserted the washers, coat the upper face with Elmer's glue - PLA will not stick to cold steel - and resume the printing.Instructions for modifying the G-code for pausing can be found here.

I used three 1/2" galvanized steel washers left over from a remodeling progect.
