Hello! This is the generic Hoffman Tactical README text file for lower receivers. It contains info that you may want to know. For info specific to the design in this ZIP file, read the INFO text file. File Naming Scheme: "BL" means "Basic Lower". "SL" means "Super Lower". "NS" means "No Support". "WS" means "With Support". File Types Explained: .STL files are ready to import into your slicer and print. They are a mesh file and are hard to edit. .STEP files are not compatible with most slicers. They are much easier to edit in CAD then .STL files. .AMF files can be imported into slicers. They separate the built in support from the part body. This allows you to set different line widths for the support. This is an advanced technique useful when printing with a larger nozzle. I highly recommend you use the .STL files unless you need the separate support. Print Orientation: See the “Proper Print Orientation” JPEG. The lower should be printed with the bottom of the magazine well flat on the bed. The Swivel Pin Plates should be printed with the inside surface flat on the bed, the holes should be facing up. Recommended Print Settings: You are welcome to experiment. However, I recommend the following basic settings. The outside line width is very important to insure the built in support prints successfully. Cura is an awesome slicer, however I believe Prusa Slicer (Slic3r) is easier to use when printing most parts. The advanced settings available in Cura are not needed. 0.20 MM Layer Height. Three Walls (Yes, more walls are not always better ;) 100% Aligned Rectilinear Infill. Standard Rectilinear will work, but is not nearly as strong. 0.45 MM Outside Perimeter Line Width. 0.40 MM Top Layer Line Width 0.50 MM Line Width everywhere else. I like to keep print speed under 45 MM/s for optimal layer bonding. But this is not a hard rule. All other settings are dependent on filament and circumstances. This is not the place to discuss them. For the Swivel Pin Plates, I would use four walls and 50% Gyroid or Honeycomb infill. Basic vs. Super Lower: The Super Lower is designed to fit the brass inserts from our kit. The Basic Lower is designed to use as many standard parts as possible. If you have one of our kits, print the Super Lower. If you think that your fire control pins are too short, you probably printed the Super Lower and have not yet installed the Bushings in their pockets. The Basic Lower will need the pistol grip bolt hole tapped to 1/4-28. Built In Support: The built in support is designed into the CAD file and replaces the slicer generated support. I highly recommend you use the files with support (WS) unless you have a very good reason to do otherwise. Sourcing Parts: A standard lower build kit will be needed to complete any lower. Unless otherwise noted, a mil-spec carbine buffer tube must be used. If you do not have a kit, you will need to source the hose clamp and swivel pin plate hardware yourself. The front plate hardware is two 10-32x1.25 bolts and hex nuts. The size of the hose clamp is dependent on the lower you are printing. You can find more info at hoffmantactical.com
