Anyone want to print with no overhangs? Files on Printables!
I am not sure if I clipped this correctly - If I didn’t, skip to 1:39

Thought these were pretty cool, I’m gonna print a couple and test them out! https://makerworld.com/en/models/779200#profileId-716083

OHHHH, I wonder if they will work with EMT!!!
I have the emt from my mpcnc in the corner!
Threading pipe is a workout.

unless I am wrong, it does not need to be threaded!
OHh, i am wrong, crap!
Given how much force would be possible through the 3D printed threads anyway, I’d say a couple of cross-pins or epoxying it in place is probably stronger.

I think this design is probably better for 3d printing some sort of bar clamp Sash Clamp - Printed Threads Version by agmcmll | Download free STL model | Printables.com
Plus this author has some other really cool woodworking designs.

I don’t think I would want those as my only clamps. But I would certainly try them as the extra clamps you need sometimes.
Paul Sellers has some older videos on beefing up the square aluminum bar clamps from harbor freight. Those are good cheap clamps.
I own more clamps than most people, some cheap some very not cheap. Good clamps are an investment that can be amortised over a lifetime. Buy cheap clamps to get you by, but you will never regret slowly amassing a useful collection of the quality ones.

This is neat. They talk about the engineering of the Form 4 printer

I’m about 35 mins in. The idea of having a datum held in place by screws that have flextures is really interesting.
I would rather tear down a machine than have a beer with these guys. Very entertaining. Better would be tear down and some libations.
Oh man. At 52 mins, the encorer for crash detection attached to the endstops is sweet too.
Very cool. “Poka-yoke” is a funny term, new one on me but very useful, Poka-yoke - Wikipedia

Don’t have a source on this but Imgur, but I really find those inventions funny as hell:

Meanwhile, back on the solder trace PCB for a second. So we know it’s not smart - but then neither was the whole process!

It’s so horrifying but I can’t look away.

How much of the build was actually needed

Baffling the lengths they went to to avoid doing it the easy way.

I mean, as soon as they got to the section about doing the layout in inkscape, they were at the point where just downloading and using a free PCB CAD package would have been equivalent work. In most you can draw traces and place pads directly.
It’s just so, so, SO much more work to do it the way that they did it and I’m still pretty convinced it’ll be significantly less robust than a properly made PCB.
It’s impressive that they went that far and got it to work as well as they did, and I hate being the guy who goes ‘they should do it the way that everyone else does it’ because that attitude doesn’t lead us to new technologies etc.
If this was for the ‘let’s see if we can do it’ then I’d be all for it. Presented at the start as ‘we should do this with a PCB but we don’t know how’ is where it’s kinda awful.
Lot’s of lessons in there, though. Especially the one about backups. Get a Dropbox account or similar and work in that. Best thing I ever did. So many people I know spend so much more money on DIYing a backup solution vs just using Dropbox and periodically keeping a local snapshot.

Coming from a place where I would not know where to start, I totally get what they’ve done.
Yes, I would have asked you blokes and you would have set me off on the straight and narrow, and arguably there are many better ways to do many of the things they have done on project Binky, but a bloke’s got to have a hobby I guess!

Exactly that. If I were cracking into mounting an engine or fabbing a fuel cell I’d look at what they’d done and try to follow things that looks like industry best practice.
That’s the thing here, they’ve had no problem recruiting outside help for things like the upholstery, paint etc. They could have just as easily thrown up a post somewhere going ‘How would you do this, what would you use?’ and had 500 responses saying ‘Use EasyEDA, it’ll take you 10 minutes to get started, heres a good Youtube tutorial.’
It makes for a good video with a decent payoff and as Youtube creators there’s probably a lot of engagement to be had by doing things the insane way, especially when it works, so there’s definitely that aspect of it…
