Optimized Yarn Bowl

Overview I wanted to print a simple yarn bowl as a Christmas present for a family member who loves knitting and crocheting, but found existing designs were based on carved wooden bowls not optimized for the 3D printing process. As a result I created this design which uses overlapping bowl walls to hold the yarn in place instead of the spirals which are common in other designs. It has turned out to be very easy to use and popular with the knitting/crocheting community. This design is easier to make because: No support material is required (no overhang exceeds ~50 degrees to the vertical). It is a single part with the base integrated rather than a separate part as with some other designs. Reduced post-processing is required, primarily due to absence of support material. Recesses for weights to be added are included in the bottom. These are 20mm in diameter and will fit washers, nuts and low value coins which can be easily glued in place.
