Thats what this thing is designed for, if indeed it has pockets for the nuts. The m4's generally have a pocket, but the m3's in the wave bearing carrier are plumb bare. > You can simply print M4 > size threads inside a hole and screw the cap screw into the threaded > hole.

And of coarse I have red and green. :( Got the second one running, fairly quietly, but I do need to split it and molycoat the wear areas. 3rd one has a slightly smaller flexgear about 5% built, hopefully it will work with one of the ring gears I have a pile of at various sizes, flow looking good at 100%, even on the brim. Running at 210 and 55 once past the startup layer, I read someplace where strength was enhanced with less cooling under the nozzle, more time to weld itself I guess, so its running that fan at 55%. And I've resliced with some elephants foot comp ( 0.5mm) enabled. Thats why I had to take the first white one to the lathe and shave that off. That was not a problem with the black, but that stuff is more brittle than the white. And I'm outta m4x10 ss cap screws and m4 hex nuts, miss-counted badly. Monsterbolts and my banks MC is my friend. :) > amazon.com/Threaded-Heat-Set-Inserts... > <https://www.amazon.com/Threaded-Heat-Set-Inserts-connecting-injection >/dp/B07BH5X252/ref=sr_1_18?dchild=1&keywords=m4+brass+insert+3d+print&q >id=1598128018&s=industrial&sr=1-18> That would need the source .stl's modified, and I don't know enough about freecad to attempt that. So I'm stuck using the designers fasteners. Thanks Chris. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
