100mm / 4" Truncated Ball Valve Type Non-Clog Blast Gate for Workshop Dust Extraction Network

I printed with a 0.5mm nozzle, 0.2mm layer height, and extrusion width of 0.56mm, which is not dissimilar logic to your own settings, although your extrusion width is less than the usually accepted 112% of nozzle diameter, at 105%.
My printer is a modified Anycubic Kossel Linear Plus (DUET2 main board running at 24V, & reprap firmware V3.4.6). Yours is a more refined printer and probably prints more precisely. My experience is that my printer tends to print gaps (like holes) slightly filled in, so I think the case and ball print slightly thicker than expected and result in the 0.5mm gap, that I designed between the two, being slightly narrower. There is therefore friction between the ball and the case with my prints, which you're not experiencing.
Why don't you upload your modification to Printables. It'll probably help someone else.
@PeterH1500 I used a .4mm nozzle, .2mm layer height and a layer width of .42mm printer is a bambu x1c if that makes a difference (edited)

Thanks for your interest in my truncated ball valve design.
Perhaps before changing/adding to the design, we could just look at why your prints have given you a problem that no-one else has commented on.
Please could you say what size nozzle you use to print with, what layer height, and what extrusion width.
Best wishes,
Peter
I printed 4 of these and I'm mostly happy with them. The only issue I have is there isn't enough friction to hold the valve in position. I ended up having to make something that I can use to adjust friction so the vavle is held in place. If you could incorporate my change I really think it help everyone. All I did was made a button and glue it to the back bearing. Then made a ring that has a m4 bolt that is used to tighten the ring if needed. Incorporating it into the original drawing would be easy and make it cleaner looking.
