Big Fin Jig

Another fin jig. One is for 4" body tube, one is for 2.6". I made a hole to hang the 2.6 version after making the large one first. Pics are the 4" jig.

The fin holders are sized for 1/8" (3mm) fins.They extend up about 2". If you need a wider gap or taller blades, feel free to mod the jig.

Pics show the 4" version. This is just friction fit to the BT.

BEWARE: ... the 4" version just barely fits on my Ender 3. It popped off one of the clips holding the bed when it started printing the skirt. No harm done, just a warning.

Pictures are distorted. And Thingiview is 90-degrees off. Hey Thingiverse! Why are the pictures distorted???? And why isnt my model flat on the ground???
