Done. Also did a 5/16" slot as an example.
.

Outstanding. Thanks very much.

Question: On many of your filenames you have 100MM listed. At 2.54 cm/inch, I get 3.937007874 inches.

What am I missing here? I'm sorry if this is a dumb question.

Offset variant created. Looks quite good.

Outstanding. Thank you.

Could I trouble you for one more mod? If you have the time and inclination, would you produce a variant that is 5" long? It lowers the price of the plastic printed models .....

Re: Need to design mixing valve (pay to forum or members)

There is a few books. This one is from sliptonic, one of the main Path Workbench programmers. https://www.amazon.com/FreeCAD-Inventors-Practical-Examples-Descriptions-ebook/dp/B07H9RV5X6 But do notice that FreeCAD evolves quite fast, so some things may become obsolete and no longer match the curren...

Re: Need to design mixing valve (pay to forum or members)

If we increase the diameter of the ball mill, but keep the same depth, that should increase throughput while eliminating these weak points. Without any background where and how this will be used I can not recommend a good solution. One way is to move the cuts along the shaft and so they will inters...

Re: Need to design mixing valve (pay to forum or members)

IMO https://liberapay.com/FreeCAD is best but others may chime in, there is also for example https://www.bountysource.com/teams/freecad Liberapay would not let me make a one-time contribution. Bountysource simply hung up (repeatable) with the text "Verifiying" on the screen. I took my shields down ...

Re: Need to design mixing valve (pay to forum or members)

Can we determine the width of the "nub" on the end and increase the grove diameter by the same amount? Not sure what exactly do you have in mind. Could you mark it over the image? It sounds like you want to remove those little protrusions? they are formed by the intersections of the cuts. Maybe jus...

Re: Need to design mixing valve (pay to forum or members)

Can you post the endview? You mean the whole 10" like this? Good enough. For some reason the aspect seems different. Maybe my eyes are strained. Can we determine the width of the "nub" on the end and increase the grove diameter by the same amount? Can you recommend someone who does 3D prints?
