There's a (reasonably) easy way you can increase the wall thickness on the sleeves with the whole piece being a single model. Here I've combined all the parts into a single STL file: Now we need a cylinder - you can whip one up in most programs in about five seconds or just use this one I whipped up in OpenSCAD in about five seconds: cylinder.stl Now add the cylinder to the scene: These things are the same colour so it's going to be impossible to see which is which... we're turning it into a modifier anyway, so with the cylinder selected open the Per Model Settings tool and click the third button at the top: Don't worry about all the values there, we'll get to them later. But for now, our cylinder is transparent so we can actually tell the two apart: Okay, it's a bit big. And in the wrong spot. We need to make sure it's in the same place as the gear, so click the gear and open the move tool: It's the first object I added to the scene, so it's in the centre by default. So now we just move the cylinder to the same position, click it and in the move tool enter the coordinates 0, 0, 0. It's still too big, so open the scale tool  and turn off Uniform Scaling. Set the X and Y values (in the text box) of the diameter of the area you want to change and and lower the Z to make it a bit shorter (it's alright if it's a bit taller than your gear it doesn't matter): Now if we look in the preview view the whole model has the same walls: (and that transparent bit at the top is just the cylinder we're using as a modifier) Select the cylinder, open Per Model Settings again: All those 0 values showing in yellow means "this isn't being changed". But we want to increase the wall thickness! Set it to whatever you want. I want 2mm of walls! Now if we look at the preview... that's one phat centre: You need to group the gear and the cylinder modifier like I showed earlier. If you want multiple gears in one print, group them first, then multiply the group. I'm attaching the one I just did but please do it yourself, it really helps the memory to practice doing it yourself. CCT_SingleGear.stl CCT_SingleGear_Modifier.3mf

Hi all, Stripped this from the github UM3 assembly as I need to make a couple up (the second hand machine I just bought had nuts and bolts in place of this captive nut  - meant I had to strip down the LHS of my Ultimaker to reattach the feed unit.) Please see attached dimensions to save you the work. I'm not going to bother stitching in the teeth, just hot melt glue it into place.   Admin - if there is a better title, please feel free to change it. Regards,   A

Easy,  Old one pushes out, new one snaps back into place. Went looking for the part number, found this instead. https://support.ultimaker.com/s/article/1667417570859

The main reason I went this way was so that I could increase wall  thickness on the sleeves without increasing wall thickness of the whole print. If I redid the model as three separate pieces within the same model, would I then import the 3 models into Cura and then group them together.?  

Merci je vais essayer ça 🙂
