maximum black ice timer

3D printable ice release timer mechanism designed to need minimal supports for printing and ensure the highest degrees of reliability and consistency. main points: >flat base to allow standing in freezer attachment hole at base pyramidal interior ice vessel to reduce expansion stresses overflow holes in sides so that it can be filled precisely with little care fits zip ties up to a tested 1/4 inch and below - string is also usable 90% scale model tested to 2 hour time delay (print settings in info) This has been designed using 30 degree draft angles all around. This means any printer capable of having an overhang 30 degrees from vertical can print this with only a thin support along the axis. The orientation on the bed is such that the layer orientation does not pose a catching risk on the zip-tie. *Use care to ensure that any object inserted to be frozen in the ice will not catch in any way on its way out of the vessel. Load bearing capabilities untested and highly doubtful *
