Griffin Frame connectors - modified Al extrusion cross-section

thingiverse

I changed the v-slot cross-section so my poorly calibrated volcano could spit out the part more accurately. Sheepdog has the clearance printable on a typical extruder setup, but I had trouble with the rounded corners - the plastic would round them out too much and then the rails wouldn't fit properly. Trying to print a 90-degree corner rounds it out almost as much as the original file. It might just work. It shouldn't be an issue if you're printing on a normal-sized extruder/nozzle setup. With these STL files, a 0.8mm nozzle, a 0.93mm extrusion width, and .64mm layer heights, the rails slide right in! Print Settings: Printer Brand: RepRap Printer: Prusa I3 Rafts: No Supports: No Resolution: 0.64mm Infill: enough perimeters Notes: Printed with an E3D volcano hotend with a 0.8mm nozzle. I did have some issues with the corners (of the V-slot profile) rounding when printing perimeter first, so I just lowered print speed to get it to stick in the corners. I used Inventor to make the V-slot profile and Blender to perform boolean subtraction. I had to throw it through Netfabb too.
