Cartridge Holder for Reloaders (.38/9mm and .308 versions)

thingiverse

Reloading tray holds up to fifty .357, .38, 380, or nine-millimeter cartridges. Reloaders will find these tools handy to have on their workbench. I've recently added a STL file for a version designed specifically for the .308 cartridge. This longer cartridge requires a deeper tray. These files are sized for one diameter cartridge, but it's easy to make them work for any size by simply scaling up or down in your slicer. Estimate a scaling factor and print the first eight layers before checking the size with your desired cartridge. If necessary, cancel the print. Print Settings: Printer: I3 clone equipped with a Bowden extruder. Rafts: None Supports: None Resolution: 2.5 Infill: 100% Notes: This design is very prone to warping, so it's recommended to use PLA or similar materials. ABS will cause the corners to lift every time, resulting in an unsatisfactory print. The .308 version may even warp PLA on a heated bed, so use a brim or raft and pay attention to adhesion methods. This design is quite strong and rigid, making PLA more than sufficient. PLA settings included 220 degrees head temperature, sixty degrees bed temperature, fifty millimeter speed, no fan, retract enabled. A layer height of .25 works well. Using Cura, my printer required three line walls and four layer bottoms to achieve good results. Post-Printing: Removal from the bed can be a bit challenging. Allow it to cool completely before working slowly with a putty knife or similar tool. Design Process: This design was created in Fusion 360 using basic rectangles, dimensions, extrusions, and fillets. The Fusion360 archive is available in the files section.
