A year ago, I bought my kids a 3D printer for Christmas, and

it was one of my most devious parenting maneuvers yet.

See, they thought I was giving them the means to make toys and fidget gadgets.

But what I was actually giving them was some motivation to learn a little bit about 3D printing and 3D modeling, which I hoped would serve as a catalyst to getting them a little bit more curious about the technology around them and how it actually works.

I've been selling 3D printed fidgets to classmates.

I went to the Entrepreneur Fair last week at school and made 200 bucks, which puts my total at 500.

Now even the teachers are apparently getting in on the action.

These are apparently super popular with the adults.

This is your number one seller right now, right?

When I learned that the storm that hit our mechanical room was an entrepreneurial hurricane, the first thing I did was bring home some Idol 3D printers and the Prusa Core one that.

Unfortunately, the second thing I didn't do is organize our newly planted print farm.

And we have learned extremely quickly that scaling up takes more than just printers.

And there's no time to lose because next week is round two of the Entrepreneur Fair, and

Randy here sold almost all of the inventory that he prepared for the first one.

Just like Colton's team sold this segue to our sponsor, Meta PCs.

Check out this beauty of a custom printed chassis.

It's meta PC's Night Reaper pre built, which comes fully equipped with an AMD 9800 X3D, one of the best gaming CPUs on the market, as well as an RTX 5080, making it an absolute powerhouse.

Pick up one today and use code LTT to save a few bucks.

Okay, we can talk about filament later, because first, there are a lot of things to address here.

Some of them are obvious at the surface, like the total lack of organization of our workspace, but

some of them are a little deeper, like the destroyed print head on our OG machine, this bamboo P1s.

Well, let's start by fixing that as something of a 3D printing novice.

Hot ends are something I don't really know a ton about, and it's a surprisingly deep topic.

I chose BQ's PandaRevo Hot End with a mix of brass and obsidian nozzles and in a variety of nozzle sizes.

These are going to help you change your nozzles really fast.

And obsidian is great for abrasive materials.

Your core one doesn't really need this because it's got a pretty good system already.

I worked for a couple 3D printer manufacturers.

My last job was as an editor at a 3D printing publication, and I work here now.

You drilled me on Star Wars a couple days ago.

This has been out of commission for almost two weeks.

Like, you got a whole bunch of filament on it, and

then when you were trying to remove it with a torch, you, like, killed it.

Yeah, somehow we melted the temperature probe by accident.

Okay, let's go ahead and throw the new one on.

Theoretically, this is as simple as just propping it on there, and then we're good to.

Wait, are you sure you don't want to put the fan on first?

And we should probably call out the Precision Screwdriver from lttstore.com Great for these types of jobs.

I don't know how he managed to drop the screw, because it's magnetic.

Also, we've got new sizes now, so we got the obsidians in 0.4 and 0.6, and

we got a brass nozzle not just in 0.4, but also 0.25.

So if you wanted to print finer stuff on this one, then you could.

if people are willing to pay a little bit more for a finer print, then who cares?

Or rather, just needs being willing to force things a little bit.

Yeah, I don't want to break the new nozzle either.

These are way more expensive than our old ones.

The obsidians are, like, twice the price of a brass nozzle.

So the deal we have with him and the girls, for that matter, is we have no problem encouraging their entrepreneurship.

We're willing to provide the equipment, but consumables they need to reimburse us for.

And I haven't figured out where hot ends figure into this.

Oh, now's a good time to mention that we got some new desiccant that you can put in your ams.

These are the silica gel desiccant packs from wisedry.

And they are rechargeable, which means that they'll change color when they're too wet.

And then you can put them in a microwave, a stove, or just your filament dryer to recharge them and put them back in.
