Here are some good working scales for the spyderco tenacious.
This is not my original design but I am not sure where I found it.
I had been looking for awhile and kept finding mesh files that I could not get a chamfer on or get cleaned up for a good print.
This one took a little work and some cleaning up but works well now.
I print with the faces flat to get that nice PEI finish. I use no support though there are some finger indents that will take some post processing if you use supports or not so your call.
I wanted these strong so printed as 100% infill.
My next step will be to print in glow in the dark PLA.
Enjoy.
