Wrench for 1/4" tubing "e-torx" nut fitting

prusaprinters

Instructions on my RO water system said "tighten with wrench" and yet there was no wrench to work with these. Will probably post pics later. No supports, I printed in PETg with like 4 walls will just make the front end solid.It fits some nuts just right, and some too tight, use horizontal expansion to get more clearance if you… have large nuts.(I uploaded an untested, 0.6mm looser wrench, may not have same bed adhesion. Called 5L.)
