I had some missing LEGO bits, so I found the components on ldraw.org, converted to STL with LDView, and butchered them together with Fusion360.

In this case, I merged 3 parts into one, so I'd only have to deal with 1 interface instead of 5. The sanding probably made it worse.

Wet sanding (with appropriate sandpaper) makes a huge difference, especially for smaller grid sizes.

But it’s probably easier to just get some individual pieces from Bricklink.

Not really pirating IMO

I know it's not the point of the post but I still wanted to mention PrintABloks

These are made specifically for 3d printing and I just think they're cool and better for our community :)

That and the creator of PrintABloks (3D Printing Professor) is a great and passionate dude

Might look better with a coat of primer and paint

Due to the relatively small size and overall complexity/tolerances required for the object, I wonder how it would have turned out if done on an SLA printer.

[–] pennomi 6 points 1 year ago

Yeah the tolerances on LEGO are high enough you really need a resin printer for good results.

What did you print it with?

[–] p1mrx 3 points 1 year ago (1 children)

Ender 3 S1, with Klipper on a Raspberry Pi.

I wonder how it would turn out with a resin printer.

This is the way, if you want small details, FDM is not your choice.

How is the clicky-ness? Does it snap to regular LEGO well?

[–] p1mrx 5 points 1 year ago

It fits well enough to hang upside down, but I didn't do much fine tuning. https://github.com/paulirotta/PELA-blocks#calibrate would probably work better for generic brick shapes.

I had the same experience. While I was very happy with the "clickyness", the color and the feel, it just takes to long to produce enough parts (FDM with 0.25mm nozzle and 0.05mm layers)

[–] drudoo 3 points 1 year ago

I’ve had the same experience. Not worth it and too much of a hassle to calibrate for proper snap.

[–] [email protected] 2 points 1 year ago

If it was that easy, Lego would've gone out of business years ago

[–] [email protected] 2 points 1 year ago

Seems like this would be better suited for creating a resin cast.

I've seen people 3d print Lego, bit it's usually scaled up to gigantic proportions
