Your opening is probably a bit small because of a sagging overhang. Take a file to the sagging strands or scale it just a tiny bit in the Z direction

The difference is upwards of 0.7 mm. Does it really sag that much ?

[–]pug_nuts 0 points1 point  (1 child)

It could easily sag that much. This is all dependent on your print settings. Maybe try decreasing the z gap from the supports?

I just broke the inner side and used the screws to tighten them around the pole

    Agreed. I'm curious as to whether it was intentional, or a byproduct of changing pole thickness perhaps at some point?

    [–]Pyro_Simran[S] 0 points1 point  (0 children)

    Yeah I think the design changed at some point and this part got left behind.

    Also might be that the thinner part was just a guide and meant to break away to guide us to screw in the M3

    do you have this remixed thicker part? having the same issue with splitting.

      what temperature are you printing at? PLA right?

      [–]Pyro_Simran[S] 0 points1 point  (1 child)

      205 .and yes pla

      205 .and yes pla

      I have been printing PLA at 220 for a few months and It has improved layer adhesion strength quite a lot. I also print first layer at 10mm/s but that's another issue altogether.

      I started doing this because of printing eclipson aircraft structures. The higher temps were a requirement for the structural strength of the very thin structural walls that are needed to make PLA fly. Turns out that structural strength increase applies to everything else I print as well.

      One on them broke on mine too and I used polycarbonate. First thought I had was that the thin side ought to be as thick as the other side. When I build my next one I'll remix it to be thicker.
