Jointer or planer honing jig

Hone your planer/jointer blades.  I made an 8" one and a 6" one.  I would have made a 12" one, but I thought that not many people can print 12" high.  I print it on end. I created a coupler so you could glue multiple pieces together if you needed something longer.  If somebody wants one like 12" long, let me know.  You will need some M5 knurled heat inserts and M5 set screws to complete the build.  It takes blades up to 1/4" thick

I have added a larger blade version that adds some extra support(blade seats in farther) down at the blade if your blade is wide enough.
