    How good are the stock threads?
    My retirement plan is: Civilization will probably crumble before I'm 65 and money will be meaningless anyway.

    Somewhat of a tight fit but it seems to be secure. I think I have enough parts to put everything together.

    Look great! I am anxious to hear how well the plastic holds up to the forces flexing it when you fire it.

    So, almost a year later.

    I started to assemble the Vanguard version and found some minor issues. Primarily some finishing (drilling & filing) to make things fit.

    The bolt catch roll pin is causing me issues right now, because of how the lower is designed.

    So . . . back to the drawing board. I got all the parts in, except the buffer tube. I had to do some finishing and drilling, but I expected that.

    Unfortunately I didn't do the math for shrinkage (insert Gambit joke here). Usually it isn't a problem, but it is here.

    So I'll have to fix my printer and do some tests to re-calibrate the model.

    Did you build the printer? Where did you get the parts for it?

    I have been toying around with the idea of maybe building a CNC router but some of the prices for components are crazy expensive. I am not going to drop $3000 just to test an idea for a tool that I may even use much when it is done.

    It was a hobby off-the-shelf printer. An Ender 3 Pro. I've made upgrades and modifications to it since I've owned it, the last piece was a calibration tool that helps my prints.

    Yup. I wish there were more entry-level CNC routers out there, because that is something I want to get as well. One recommendation I got was to purchase a used CNC machine as they usually still have some life left in them, or just some minor repairs that are easy.

    I'm hoping when I move I can get enough property for a machine shop/hobby room to put these things in.

    The shrink may not be the same throughout the X, Y, and Z axis also. When I was doing foam seat molds and gas tank molds the shrinks were always different and changing

    For my vac forms or injection mold the standard shrink was 1 mm per 100mm, or 1/8" per 12".

    I was told to leave some tools for for night shift towelheads to use.

    I left my grandpa's shrink rules out.

    They messed up some stuff.

    I got everything in but the buffertube, the threads were just slightly out of alignment and it messed up threading it. I cut out and printed a few different sections where there were problems(where I had to drill/sand/cut) and I think I have it dialed in. I also added a sensor to my printer so I won't have to fight with alignments as much.

    I just wish it didn't take 30+- hours for a full run.
