Cat's Eye Iris Box

Unlike those other fussy print-in-place iris boxes, this prints and assembles easily with no mysterious “breaking free” process. All parts snap together with no glue or fasteners. There are a couple of small built-in supports that easily break away (leave your slicer supports turned off) and a couple of small brim “patches” where the edges might be inclined to lift.PrintingPrint this in PLA with 0.2mm layers. Print 2 of the Lids and one each of the other parts. After printing, break off the built-in supports and brims and clean up any strings or nits. On the interior of the spherical mating surfaces, sand down any ridges from over-extrusion at the edges.Pro Printing Tip: When printing convex overhangs, the overhanging edge wants to warp upwards. The steepest overhangs in this model are the lower halves of the hemispherical pieces. To minimize warping, orient the hemispherical parts so that the fan is blowing onto the outside of the hemispheres. Note: It is possible to scale this model
