This five-part print is a tofu press for draining the water from bricks of tofu. In addition to the printed parts it also makes use of two (2) C-756 utility compression springs (23/32" x 3-1/2" x 0.41"). The ones I used are made by Century Spring Corp.
I did find that on one of my prints the locking arms of the lid spread a little bit wide during printing, resulting in a press with week locking. To remedy I heated each arm individually with a hair dry and bent them back in slightly. Do not overdue this.
