This repo contains the following folders and files:

• brackets - files for creating brackets or "ears" for different types of rails
  • bracket 2d files - DXF files suitable for laser cutting, etc.
  • fusion 360 3d models - Fusion 360 3D designs of the ears for reference, rendering, or including in a case design
  • shop drawings - PDF technical drawings with dimensions
• rail profiles - accurate models and drawings of different rail types
  • fusion 360 3d models - Fusion 360 3D designs of the rails for reference, rendering, or including in a case design
  • profile 2d files - DXF files of the rail profiles

• The three different rails represented are Tip Top z-rails (as supplied with the Happy Ending Kit), Vector rails (eg: TS600, TS169, etc from Mouser or Digikey), and Synthrotek rails (which have the same critical dimensions as Vector rails, but a different profile). If you're starting a project from scratch, your best bet is to purchase Vector rails. It's most economical to purchase them in longer lengths than you need, then cut them using ordinary woodworking tools.
• I normally like to include the units in the filename when saving as DXF since they are unit-less files, but I didn't here. Pay attention to the dimensions when you import - they are either mm or inches and the different should be entirely obvious when you open them. If you need instructions on how to open DXF files in Illustrator, see my short tutorial on YouTube.
• The holes that appear as two concentric circles in the shop drawings are countersunk mounting holes for attaching the brackets to a case. You can see this clearer in the 3d designs.
• The layout of the dimensions in the shop drawings is a bit unorthodox. It's what was useful with my vertical mill's DRO back when I made these. Don't judge - just make your own drawing from the Fusion 360 designs if you don't like the PDFs I've included. No problem.
