Bearing in mind Adam Savage is both an expert maker for DIY tools, and an industry veteran with experience on the professional machinery. There is a nonzero chance he operated the machines Lucasfilm used to make Stormtrooper armor, to make more Stormtrooper armor for Lucasfilm. Knowing he slapped one of these together is like watching Gordon Ramsay cook. He can tell you exactly what to do and you still might not get it right.

The real obstacle to a DIY vacuform table is that you need an object with the exact shape you want to reproduce... and the easiest way to get that in 2026 is with a 3D printer. So at some point you have to ask, why not just use a 3D printer. Vacuform can be a lot cheaper if you're making something in bulk. You can even do multiple parts in one go if they fit on the table. It's necessarily as thin as your plastic sheet, but instead of supports, you have to remove all the surrounding material, and maybe hide some weird seams. There's probably an argument for scale? A big table with holes is generally cheaper than a big 3D printer bed, but you're still limited by your oven.

So we are "ruled" by the lazy and incompetent, a nanny state... This will end "well".

When I was a kid we threw lawn darts over the house back and forth from front yard to back yard, what could go wrong? Gotta stay aware

Lawyers ruin all the fun in life.

And your 100% without research, some kid probably was not using it as intended and burned a house down. And no fun for us.

You can make one of these w/ a vacuum, vacuum box, and your oven.

I remember "creepy crawlers" which seemed to be the answer to the question "how do we sell an easy bake oven to boys?" It was a lightbulb in a plastic box, some pot metal molds, and some squeeze bottles of colored goo. Squirt the goo into the molds, bake it in the oven, and then you'd have little rubber bugs! Minutes of entertainment.

I had one of those vacuforming toys, it was kind of sold as a make your own matchbox cars kit. It was a lot of work for a pretty shitty matchbox car.

Those toys got proper hot, and they had metal parts that could blister a kid's finger if used incorrectly. The toys that taught me that sense of "don't touch the blurry part of a running power tool" are basically banned now because the moms that gave their kids asthma and peanut allergies by keeping them in a sterile bubble until prom night sued them out of production.

The world is a dangerous place, you can't wrap everything in bubble wrap to save the children. Getting burned teaches you lessons. Shit I electrocuted myself more than once as a kid. Now I have a very health respect of high voltage and capacitors that will kill me.

I'm going to sound old here, but Lego isn't Lego anymore. Rather than selling bricks and objects that could be creatively combined, a glance at their contemporary lineup shows mostly kits that have a pre-defined build path. Even the nominally engineering-focused Technic line (for example, compare a vintage Technic set, e.g. https://www.brickeconomy.com/set/8860-1/lego-technic-car-chassis which had a huge number of connection points and opportunities for customization with the current Technic line, https://www.lego.com/en-us/themes/technic , with little to no extensibility and almost exclusively custom formed pieces with few to no points visible).

Wut? I was talking about toys that make engineers at no point did I say that Lego or the rest were not made anymore. I was talking about this specific toy as its awesome to learn how to vacuum mold.

There are still Erector sets, they are sold under the name Meccano. I made my 1st wire suspension bridge w/ an erector set when I was 10. Fond memories.
