The Lee "C" frame press is great for small jobs like decapping, but I didn't want to drill a hole in my bench in order to catch spent primers. I also wanted to take advantage of the T track I installed in my bench, but this can be printed without the base(LeePressMount_Base.stl) and be bolted directly to a bench. If you do print the base, you can pause the print to add nuts for the mid section and press to be bolted. I printed with 100% infill just to make it as solid as possible, but that probably isn't necessary.
