Note during assembly

[jonnew]

These are things I noticed during assembly that I thought may have some room for improvement, or not. I'm planning to amend this issue as I go.

1. I think the foot part should have embedded nuts. Mine tap holes were very loose. These could be slotted in from the side.
2. I missed the part about embedding nuts during 3D printing. This is cool, but its a huge manual step that is not amenable to e.g. manufacturing of several hundred 3D printed components. I think I would prefer just having a spot for embedding a hex or square nut with glue post print.
3. Screws that are used as spring tensioners should probably be semi threaded with their threads not in contact with clearance holes (my build is a bit jacked, so this might be an overblown comment that goes away).
4. There is a very common type of brass lead nut for T8 lead screws that does not fit onto the waterjet cut pattern. It might be good to support this mounting pattern along with the 3-screw version for the Stepper Online plastic lead nut.

Thanks Jon, I really appreciate the feedback!

I updated the designs for the foot, knob, and plunger clamp so they no longer require pausing the print to embed nuts.

I suggest printing with 0.4 nozzle and <=0.2mm layer height. I printed the plunger clamp with supports. The supports popped right out when I removed the part from the bed, but if that doesn't happen they should be easy to remove by pushing a screw through the hole to clear it out.

Here are the new files: 251203.zip. If you get a chance to print them, let me know how it goes.

I added a 4-hole pattern but the features may be little too close. I'll see if it's manufacturable next time I place a waterjet order. May have to just provide a separate design file for those who plan on using the common brass nut.
