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

thingiverse

Reloading tray holds 50 .357, .38, 380 or 9MM cartridges. If you reload, these are handy tools to have on your bench. I just added the STL for a version for the .308 cartridge. This is a longer cartridge that needs a deeper tray. While these files are sized for one diameter cartridge, it is easy to make them work for any size by just scaling x and y up or down in your slicer. Guesstimate a scaling factor and print the first 8 layers and check for size with your desired cartridge before continuing the print or canceling. Print Settings Printer: I3 clone with Bowden extruder. Rafts: No Supports: No Resolution: 2.5 Infill: 100 Notes: This is VERY prone to warping so use PLA or similar. ABS will lift the corners every time leading to a very unsatisfactory print. The .308 version will even tend to 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 so PLA is more than strong enough. PLA settings were 220 head, 60 bed, 50mm speed, no fan, retract on. .25 layer height works well. Using Cura, my printer needed 3 line walls and 4 layer bottom to get good results. Post-Printing A bit difficult to remove from the bed. Let it cool completely and work slowly with a putty knife or similar tool. How I Designed This Designed in Fusion 360 using basic rectangles, dimensions, extrusions and fillets.
