didn't you hollow it out ?

well that's easy enough.
Copy and paste the first module.

just reduce the size of the original by 2-3mm all round. Call it removeblock module. And difference the two modules.

You can repeat that script for different size and shape blocks.

If you are smart, you ought to make sure your lego blocks plug into the real ones. That way, you can tell the parents to go buy the normal ones. And you can print the cool, specialty ones the kid needs (wants). Otherwise, you are going to be printing millions of these things!

[curious aardvark]

Yep - but you can actually learn a lot by doing something the long way round.

Example I had no idea that you could use the facet command for a single model rather than as a purely global variable.

So when i made this model: http://www.thingiverse.com/thing:582323
I had to work out how to program a polygon script. Learnt a lot doing that, which I would not have learned just using a six faceted cylinder :-)
I now know both ways :-)

In case you're wondering I'm the idiot holding the duck - yes i should have been wearing gloves. That thing stings !
But it works :-) And i enjoyed working out a fully parametric polygon generator.

You'll never get a shine on that duck doing it that way. Your buffing wheel needs to go faster and use some polishing wax.

What's a facet command? Searching the OpenScad manual doesn't find any reference to that.

Update: I figured out what you meant. I suspect you are talking about the $fn parameter????

cube (32,32,20);
is the same as
cube (32);
and is a cube

cube ([32,32,20]);
Is not a cube it is a rectangular cuboid.

ie. without the square brackets the second and third dimensions are ignored.

"center=true" and "center=false" can be added to most shapes and needs to be watched. It is often easier to set it false/true than to do a translate.

[curious aardvark]

yep the $fn= command is the 'number of facets' command. Hence the 'facet command' :-)

And yes I am definitely a pheasant pluckers son. My dad was a poacher way back when I was a wee sprog (and we are talking a long long time ago). Only way we could afford regular meat.

lol - yeah wax could work.
Apparently you melt a bucket of wax, dip the bird in, wait till it sets and then peel it off with all the feathers.

Quite where you buy bucket loads of wax from - not a clue.

We'll see how the mkII de-featherer works when i finally get a chance to make it.

Ah - that makes sense. But wouldn't it bugger up the model ?
I have to admit I never do the shortcut method. Always type the full ([0,0,0]) in before I add the numbers.

It looks like curiously 'ard wark to me, I'll stick to the butcher for my meat.

[curious aardvark]

lol - nah, game is cheaper, healthier and once you've done a few, the processing is no big deal.
It's also the cleanest and most human way of killing something.

I use pigeon breast for a lot of dishes where you'd use good and expensive steak.

Buy a goose in the shops and it'll cost you upwards of £35
The one we've currently got didn't cost anything bar a little processing.

The other night I spent a couple of hours deboning a big muntjac deer. Ended up with 2x3lb haunch joints, 2x2lb shoulder joints, couple racks of ribs, about 2lb fillet (that alone would have cost more than I paid for the whole deer) and about 3lb scraps I'll use in sausage and burgers.

Total cost= £30 and a couple hours of my time.
Like I said the fillet alone would have cost more than that from a butcher or shop.

Game is not only good for you, it's really good for your wallet :-)
