Here\'s a peek at what MakerBeam looks like!

We were hoping to get this printed awhile ago, but people get busy, things happen, and apparently boards fry on neighborhood MakerBots, so here it is: a 10 cm long mockup of MakerBeam.

We call this a mockup because the beam profile will not be this exactly. This should be easier to print, and we\'re not quite done revising the tooling documents with our manufacturer. It\'s got the basics down: a 10x10mm beam with a 3mm slot. It won\'t hold circuit boards or other thin panels as well as the actual extruded beam.

Many connectors one might design based on this profile will work no problem; some might have to be modified slightly. Have fun playing around!

The original file has multiple problems for printing and is included as a reference. The 10mm standing file and the 15x15mm file print fine according to Erik de Bruijn, who made the modifications. I recommend printing the 15x15mm model to end up with something you can play with.



I'm guessing you'll want to print this with the Z axis running parallel to the beam, which is not how it is in the model; sorry about that, I'm a baby to the world of 3-d.

The dimensions are 10x10x100mm, so the Z axis should be 10mm long. I'll post a shorter beam, later, so that people can try scaling it up to 15x15mm; I think it might work better in its own right at that scale. Obviously we think 10x10mm will be plenty for aluminium!

´m missing makerbeam on

Does anyone have solid-filed (step, iges, proE,...) of these
to make designing some connectors easier?

This is another similar profile that is a bit lighter weight in construction, http://www.thingiverse.com/thing:1130http://www.thingiverse.com/thi...

Microrax 10mm profile

Did you guys have to substantially modify the STL file to get it to print? I am having all kinds of issues using Skeinforge, and when I opened the object in Blender, it has some interesting vertices and faces...

Can someone post a working version of the STL file, in the right orientation?

The project is really cool- I can't wait until the aluminum extrusion is available for purchase.

This is quite a cool project! I ran one quick print straight from RepG and I've just uploaded one to the SD card to fix the few pauses I had during the first build. Other than the user error on my end it printed well :)

It's real strong too, I just tried to bend it to see if it would break and it didn't budge!

This 15x15mm profiles look incredible, Erik. That's really exciting. From looking at a MakerBot printed Statue of Liberty I thought 15x15 was probably the smallest useable profile in ABS.

Those meta-blocks look like they could be modified to work with the beams...perhaps that's what was on your mind? 8-)

Updated the page with Erik's cleaned-up models as well as his 15mm scale up. Use that one if you want something well-defined enough to actually use. Thanks Erik!

Erik that's great, thanks! I'd like to get an end-on shot of yours and cyrozap's beams to get a sense for how well the slot printed on the machines. You used a RepRap, correct?

I'll post a 6 cm beam later today, that could be scaled by 50% to give a 15x15x90mm profile which i think would probably be more fun to play with in ABS. Also if I get a chance I'll put up some 'tie ribbon' that (theoretically) fits in the beam slots.

Feel free to send me an address at our website and I'll get you a piece of MakerBeam. Thank you, to both of you :-)

B.t.w. this is the tallest thing I printed so far. Thanks for the interesting tes. More pictures here:
Gonna print a slightly wider version that fits tapered M3 bolts.

Cool. I like this project. I hope you get going. I'm interested in using aluminium profiles, since it would be useful for al sorts of projects and very complementary to RepRapped 'specialized' parts...

good job cyrozap! Just get me your address, and we'll send it to you when we have it! Contact emails on the main MakerBeam page.

anyone else out there working on this, take heart! You, too will get a free piece of beam if you post your printed model, the more angles and detail the better. It doesn't have to be crisp and perfected, just real. We'll keep this going until tomorrow morning or until we chicken out. 8-)

Which email address do I send my mailing address to? None seem to apply.

mine is sam at makerbeam dotte com

Ok, I made the piece! How do I get the free 10cm piece?

"Free 10cm piece of the MakerBeam production run to the first team to print the model and get photos online! Offer includes shipping to any address in the US; internationals I'll ship to but you pay if it turns out expensive."

I rotated and scaled it correctly (it was 1mm x 1mm x 10mm). Now, on to printing.
