The standard dimensions are 59x59x60,5cM, big enough for
a Prusa I3. You can expand the dimensions by simpely add some
extra parts in between. You can choose for your self to make the
frame wider, longer or higher.

On the botom of the frame is some free space available to fit in a standard 10x2mm steel or aluminum strip for extra stability.

You only have to add some plates/sheets to finisch the enclosure.
The frame is designed for 4mm acrylic or plastic sheets. You can
glue the fitting sheets into the frame and finish it nicely with the
included strips.

The higlighted red parts are all that you will need to print this frame. Add some extra pieces of A2,B2,C2,E2 or A5 and D3to expand the
dimension of the frame.


The highlighted (red) parts in the picture are all you need to make
the enclosure (standard dimensions). Below you can see how
manny of which part you'll need.

Can anybody tell me the dimensions of the panels that I need to cut to make the sides of this enclosure?

What type of filament should this be made out of? Also, you mentioned glue, is there a special glue for acrylic sheets? Thanks.

Type of filament wouldn't make much difference. ABS will be a bit more heat and stress proof, while you will get slighter better printing results (better fitting) with PLA.
The best way to glue the sheets into the frame is to use an universal plastic glue. Because you're glueing various materials together. Make sure the glue can be used to glue acrylic. ABS and PLA will be okay with most universal plastic glues.

People have been talking about this model since you posted it in 2015, but I still didn't see an entry where someone had fully completed it. I love the design and I'm really keen to give it a try, but can you let me know if you have successfully made this please. I'm only a newby and i'm not super experienced with problem solving if the model doesnt print well... Just hoping to avoid lots of failures if possible. Thanks.

Starting to print this. at 3 hours a part and only being home for 4-6 hours a night, looks like his build will take the next week or so :P I will keep you guys posted.

So, i've been printing all the A-parts for the last days, but im encountering some problems. I've printed them with 2 bottom/top layers and only 1 side wall layer with 8-10% infill. But the parts dont fit well, i need to oil them and push very hard for them to fit, sometimes i break a part with that much force. any tips?

I think I had to make a little tolerance in the connector fitting. Which material do you use to print for?
You could try to file it up slightly, that makes the connectors also a bit more smooth avoiding friction. If you use ABS, you could try to file the connector up a little bit and than finish/smoothen it with a bit of acetone. This will melt the connectors also together when the acetone is just applied.

Hope this will help!

I like the look of this, though has anyone actually printed, and built, an enclosure from this design yet?


hi, im having insues printing the pin from hinge, could u separate the hinge in 3 parts or 2 parts with the pin in a single STL?

How much Material will such an enclosure take? I belive the build-time will go into days?? :)

I have started printing this enclosure, i too had some issues with the bigger parts, tried rotating it but in the end i had to scale it down to 160mm. Will take photos when done

Did this ever work out for you?

hey mike, how did it go? could you upload some photos, please? :)

Thanks a lot for your work, it seems to be awesome !
Do you have a real picture ?
How many spools are needed to print the parts ?

Looks quite impressive! Has anyone tried printing it yet?

With my printer configuration it takes more then 6 hour for one part :(
So didn't try to print it yet. I'm updating en reconfigurating my printer at this moment, so hope to print it in the near future.

3DPrintClean is developing an Odor and Ultrafine Particle filtration attachment for DIY enclosures. Would make a great addition. See http://3dprintclean.com/3dprintclean-scrubber.htm - Disclosure, I am the founder of 3DPrintClean.

Sold as part of your enclosures, which start above $1000. It's a bit much for DIYers.

Looks cool, what did you design this in?

Thanks! I used Rhino Ceros

out small pieces of about 1.50 cm and all

Thanks! Wasn't aware of that.

Seems that the the parts were converted from cm to mm during STL conversion. It's solved now, and the
correct STL-files are uploaded.

Something still seems off. Most of the parts take up my entire 200x200 bed. The scaling is still off. For example, part A1b comes out to 165mm x 158mm and A2b comes out to 196mm long.

Thanks for mentioning. But these dimensions are as meant to be.
I've tried to design the enclosure with as few as parts as possible. So the parts should be as big as possible on the printbed.
Maybe its usefull to rotate the parts 45 degrees on the printbed with your printer software. It will help a bit.

Wow, now that I look at it again, the size is correct. My brain wanted to thing they should be smaller. Sorry about that.
