Hi!

We've wanted to share our project based on 20x20 extrusion profiles + 3d prints: Hackable DIY rig for  Biostar TB250-BTC D+ (https://crypt0.zone/open-source-3d-printed-mining-frame-for-biostar-tb250-btc-d-hackable-based-on-20x20-aluminum-extrusion-profiles)

You need to buy 20x20 extrusions, few screws and nuts for them.

We've been using this project for about 1 month now with 8xRX570 and we're very happy how it's performance.

At link above you'll find tutorial how to build complete frame from scratch :)

We'll be happy to hear what you think about it!

That's very cool, dude.
I've got a 6x Vega rig on an Onda D1800 board that is still sitting on its box, i.e. such a frame would've been perfect for me.

Now where did I put that 3D printer...

:D

@dragonmike thanks!

I don't where you're based but in some countries you could print all those things in ~$50 with recommended PETG, but still I would buy some cheap printer like Anycubic i3 mega :)

ONDA D1800 is about 10cm narrower so you'll end up with lot of free space but besides that it should fit without any problems.

Since a gap between the cards is close enough, are that vertical card's position was giving some different on cards temperature? How if just put the cards on horizontal position and give a few fans in the backside (to throw a hot air) and a few fans on the front side to take up hot air, will it more efficient on the temperatures management?

Good work!

This is amazing.  We need more posts like this one.  I wish I had merit to give out!

This ehow it should be, when I first joined BCT everyone wanted to help each other now its either someone trying to scam someone or fud and putting down other people's work but I'll merit this because it deserves it

Yeah, I felt it.
This kind of post wouldn't be interesting enough for users whose just coming here for trying to scam someone or spread the FUD, etc. This kind of post is for those that come here for discussion, getting more information, spread useful things, etc.

Design looks fantastic, very smart design and so much thought into it.

How about the temp? it looks like your this setup is fine but how about the temp and performance?

Great question, also curious about the sort of temperature rigs like this get.

But nevertheless, this is an amazing build right which makes good use of 3d printing. I would build one of these if only GPU mining was still profitable today. Maybe this could be a worthwhile project to come back to if ever GPU mining again becomes profitable.

Very nice!

With slight modifications it one should be able to build rig for ATX motherboard, I assume?

Sorry for late replay.

Thanks for kind words!

So temps we've got are:

But it was taken about 1 month about when it was full summer here. Now temperatures at gpus are about 10C lower.
About putting this rig on back - I don't need to do it right now since temps at this moment are below 60C.

Yes, with slight modifications you should be able to use it with standard ATX.
