Hey, I own that 1911

Oversteer: You will hit the wall with the rear end.
Horsepower: How hard you will hit the wall.
Torque: How far you will move the wall.

Latest toy* for the oldest (he makes odd color choices, but it kinda works):

It's from https://foamknight.com/ and only has a handful of non-printed parts. Nice things about this one over others that it is based on:

- It has a non-embarrassing design to it.
- It's much easier to assemble.
- It supports all 3 major types of NERF ammunition and makes it easy to switch between them without having to take the whole gun apart.
- Similarly changing out the main spring is a simple affair which makes it a much easier task of finding the right spring for your needs. It's actually simple enough (loose the blue knob on the end, pull out the stock, and then remove the twist lock spring door) that you could do it in the field to adjust for needs on the fly.

* I say "toy", but this is actually meant for adults in competitive games. The stock spring that comes with the kit is supposed to fire around 220fps. The weakest off the shelf spring I could find (without starting my own experimentation) is still in the 100fps array.

So from plotting some 3 years ago, I finally did what I bought the printer for in the first place. Though being me, I couldn't just be satisfied with printing Voltron. I had to go and print him at 200% scale.

After 2 months of near non-stop printing and 8kg of filament (that's ~$160 in materials), I bring you a Legendary set of boxes full of parts!

Now I have an inordinate amount of sanding, putty, more sanding, more putty, more sanding, and painting to do....

Just looking at the boxes of parts gives me a headache, but THAT is going to look pretty cool!

    I hope you incorporated an IMS bearing somewhere in the design of that thing.

    Hey Schelly, I haven't turned the printer on in like 3 months, the PLA spool never got removed and stored, and this is my first layer after turning it on and wiping the plate with 99% alcohol :P

    I may object to some of their business practices and what they think of themselves in certain markets, but they do know how to build a damn reliable printer!

    Please explain? Is it that it printed the old stale stuff or that it printed at all or that the printed material looks surprisingly even and clean?

    All of the above.

    While it's far from the worst (nylon), PLA is hygroscopic and things tend to print like shit with wet filament.

    It also shows how stable the printer is that all I had to do to it was clean the plate and it laid down a flawless first layer even though it's sat idle for a few months.

    There is no simple-as-an-inkjet 3D printer, but a well tuned Prusa MK3 ain't far off.

    My dig on Schnelly is that his printer would likely not be as friendly in a similar situation.
