The Make Something Every Week Contest

On my Huxley, it's useful to be able to turn one z-axis screw by hand when levelling the table and setting the x-axis carriage parallel to the bed - but I suppose you can manage without that or perhaps your bevel gear set-up allows you to temporarily decouple the drive.

It's spring-loaded, pushing it over 1cm will decouple them until I let go.

X-axis motor carrier and Z-axis slide, probably the most complicated part I'll need to design for this.

I ran out of blue plastic so my photos suck now. Hope the CGI view helps. Blue photographs best for some reason. Red washes out, black is invisible, blue looks like you'd expect blue to look like.

[ceptimus]

Looks good. What CAD program do you use? I mostly use OpenSCAD now.

[Corona688]

I use openscad too.

[Dingfod]

I think lisarea uses openscab.

[Corona688]

X and Z axes now complete. It'll need some kludges to make it less wobbly. That's a small piece of flooring in the middle of there, don't worry, it's nobody you know's.

This week I made an origami frog.

[JoeP]

(1) This thread is useless without pictures.

(2) Did it taste like chicken?

[SR71]

It becomes self-aware at 2:14 a.m. Eastern time, August 29th. In a panic, they try to pull the plug....

Skynet fights back.

What're you all looking at me for?

Adrian Bowyer, inventer of the Replicating Rapid Prototyper

...However - as the RepRap project has the potential to make a significant impact on society worldwide - it seemed to me that the only moral course when I started it was to put out a press release. You might reasonably ask why, given that potential impact, I didn't start a debate and only proceed with the project if the consensus was favourable. The answer is that that would only make sense if the project was something needing gargantuan resources like building a nuclear power station. That sort of project is tolerably easy to control and to restrain, just because of the enormous human, financial, and geographical stuff it needs. RepRap isn't like that: once the idea is out there, any individual with a workshop and a modest amount of cash can do it. So it would not be possible to stop the thing, even if the debate went against it. As RepRap seemed to me on balance to be good, my only rational course was to tell people and see what happened.

If it all goes Horribly Wrong, it's my fault...

X carriage is done:


Now I'm missing a bunch of belts and stuff for it though.

[Corona688]

So I managed to scare up a belt for it...



That hook shaped piece pinches the belt to hold it tight, it has a bearing to roll smoothly.



Did I mention white plastic photographs badly too? Balls.

You will be relieved to hear this is the end up updates for at least a week or so, while I wait for the electronics to arrive.

[Corona688]

The electronics have arrived.



The extruder works in a crude workbench test:



Not shown is the fighting it took to get the Marlin firmware compiled and convinced to not use Russian as its default language.

When I bought my house it had this old wall mounted gas heater in the back hallway that no longer worked. When I was redoing the floors in that area (tearing up nasty carpet and putting down tile) I decided to take it out and tile under it. This left a big gapping hole in the wall. I realized that the depth of the hole was exactly that of a standard paperback. So for years this hole was filled top to bottom with stacked paperback books. I actually liked it like that, but I knew I needed to make a permanent fix before selling the place. Well I finally got around to building a nice shelf for it. It's the perfect size for paperback books and small items like that.

[Corona688]

That is a classy non-ikea-looky shelf you got there.

[Corona688]

I thought I posted this weeks ago, but just wanted to and forgot.

The extruder works!



And the "caltrop" (I'm stuck on a better name) moves!



Now the trick will be doing both at the same time. Getting that right will be a long boring process not worth photographing.

[lisarea]

I guess this guy wins:

Daily Spoon - stiankorntvedruud

I need a fairly specific type of wooden spoon thing, so I was just thinking about making one.

It probably won't be as nice as these, but if this guy can make a whole new cool spoon every day, I should be able to make one stupid one in like a month. (I used to whittle when I was a little kid, and I was pretty good at it.)

[S.Vashti]

I had read about this guy's website of a spoon a day, but didn't investigate. I'm glad I finally did! Going through those iterations only makes me think of even more and more variations that could be done, and that's exciting, exploring the the shape and learning the basics of what makes the concept of spoon. It's a lovely physical manifestation of semantics.

Is that some kind of a seed above the red PCB?

[JoeP]

Looks like an apple seed, but the scale is wrong. Pecan nut? Capybara dropping?

[Dingfod]

Pecan.

[SR71]

Oh plz plzzzz be a capybara dropping and not a pecan!

[S.Vashti]

I made a bed frame for my bed. $20.00 in 2x4s, foam pipe insulation, and lag bolts. Now there's room under it for my dog, two cats, and about 6-8 filing boxes.

[Corona688]

It's a pecan.

A bag of shelled nuts burst while I was hiding a bunch of them in christmas gifts and now they keep turning up in weird places.
