I modeled the first piece of yesterday's components into OpenSCAD. The magnet holder slides over a section of a hexagonal shaft and holds a disc magnet to one side. The top has an extended portion where it will lock onto the cover later.
In this project, there will be three components, and the magnet holder is the first. There will be three files, and it will be essential to carry the variables throughout exactly. Right now, this means copy-pasting the values or entering them correctly, but it may be wise to use one file to select which piece to render.
I printed the first copy, but it was apparent I had the wrong dimensions because I intended to make a model with a 1/4" (6.2mm) hex hole in the center, but this was too wide. I checked my code, which rendered the hole twice as large, so I corrected the bug and printed a second copy.
At first, I was upset that I wasted time and filament on a magnet holder that was the wrong size, but I realized that I had a 1/2" (12.4mm) hex shaft at work, and I could see if my code was behaving consistently. Sure enough, my 1/4" and 1/2" models fit onto their respective shafts securely.
