I designed this die holder one day for god knows what reason. I think I was screwing around with another project which caused me to apply the same geometries to something that, well, I am more familiar with. The screw that holds the die in isn't threaded, nor is the hole that it mates with...but I'm sure you guys can take care of that if it's really important. I did my best to clean up the parts, dangling sketches, etc. however there is a plane that I just can't for the life of me fix. I tried my best for a couple of hou today... I know what it needs to do, but just can't get it to do so in SolidWorks. Maybe a bug, but whatever the case, it still should be adequate enough for rendering and practical purpose...whatever that may be ; ). I just realized that the assembly file was set to mad high resolution...making it 80-something MBs, and maybe a bit on the high side for downloading. I'll fix that in a future update. whatever the case, at least you'll get a 3/8-24NF China Thread Die in the mix. ; )
