I built a mostly printed version of the jig then built a more chunky one using wood sidewall to mount the cross sliding rods. my jig is 125mm or 5 inch wide, 8 tall, 9 long, you can likely figure the rest out.
printing:
the router clamp is PLA, all other printed parts are PETG
router clamp is a tight 68mm size printed on end with 7 outlines
3 rod stops are needed
the sliding clamp3 needs 2, one in mirror
I'm using v3 clamp slier, v4 is lower profile if you need more depth, you need 2
Needed: (I3MK3 parts)
4 8mm steel smooth motion rods 150mm, or longer for more range, get 2 400mm and cut to size
8 lm8uu liner bearings, get a 12 pack and pick the good ones, grease
m5/m4/m3 heat set inserts and hardware
wood
m6 or ¼ bolts and t nuts
small bit of acrylic glass
a spring 10mm
some experience making precise jigs
ask if you need more information. its not a very well polished project.
