Parametric storage for gaming miniatures

thingiverse

*4/13/21: This is an initial proof-of-concept draft that I will be evolving to improve usability, elegance, and utility. I am an OpenSCAD novice, so input is very much appreciated.* This is a simple OpenScad module for creating storage wells for board gaming miniatures. It can be used as-is for generating a storage box and lid for storing up to 12 miniatures, or the mini_well and mini_wedge function can be used in other OpenScad projects to create customized storage wells. The shape of a well is defined using three four-sided "layer" shapes, each of which defines the shape of the well at a given plane. The points of each layer are defined starting in the lower left corner, then moving clockwise. For example, let's say that you define your layers as follows: layer1 = [[10,0,0],[10,6,0],[30,6,0],[30,0,0]]; layer2 = [[0,0,5],[0,45,5],[33,45,5],[33,0,5]]; layer3 = [[0,0,10],[0,55,10],[33,55,10],[33,0,10]]; * The bottom layer (layer 1) is a rectangle positioned 10mm from the lower left corner of the well, offset by 0mm from the bottom. It is 20mm wide and 6mm long. * The middle layer (layer 2) is offset by 5 mm from the bottom, and positioned in the lower left corner of the well. It is 33mm wide and 45mm long. * The top layer (layer 3) is offset by 5 mm from the bottom, and positioned in the lower left corner of the well. It is 33mm wide and 55mm long. This produces a shape that is small at the bottom (designed to fit the edge of a mini base), gradually widens to the full width of the well and a 45mm length over the first 5mm, and then creates a sharper ramp to the top border of the well over the final 5mm. The format for using the function is: *mini_well(x_off,y_off,z_off,x_len,y_len,z_len,layer1,layer2,layer3)* * x_off, y_off, and z_off are the axis offsets for the entire mini well * x_len, y_len, and z_len describe the size of a cube that surrounds the entire well * layer1, layer2, and layer3 are each an array of four coordinate points that describe a rectangle A layer does not need to be defined as a rectangle, and can be defined with points at different Z offsets, as long as the points are defined in clockwise order from the lower left position. For miniatures that require an additional solid to provide support, an additional mini_wedge function is provided: *mini_wedge(x_off,y_off,z_off,wedgepts)* wedgepts is an array of eight coordinate points defining two four-sided layers that can be used to add a simple solid to a given mini well.
