Aluminum racks for miners are extremely common nowadays and quality setups sell for hundreds of dollars. You can get cheap knockoffs on Ebay for under $60 bucks or make the run to Home Depot and cut, hack, and screw together a rack of your own for $80-150 bucks. Do you trust that janky DIY rack with over $4,000 in graphics cards sitting on it?
But what about utilizing that 3D printer? Or maybe your friends 3D printer?
These simple, single GPU mining mounts are perfect for the small at home miner.
Big bulky racks are for commercial miners – PLA+ is $20 for a spool and costs about $2-3 in material per GPU stand.
I’m sure a large amount of today’s self built DIY crypto miner geeks already have a 3D printer on hand for all the dorky action figures they print out. Clearly I’m not that geek.. but uh, yeah, I happen to have a Creality CR-10s in the garage.
Plus, these are very easy to manipulate and move around your current computer desk or garage organizers. Create a cool setup that keeps cool and won’t take up as much space as a bulky rack.
3D Printed GPU mounts are strong, mobile, and cost effective!
- Cheap to print with PLA or PLA+ (under $3 per stand)
- PLA and PLA+ are 100% biodegradable material made from sugarcane
- Stable and keeps your GPU safe
- Easy to clean GPU fans
- Great for small mining rigs – print 1 or 2, then keep adding more as you go
We started with just 2 cards and have slowly built up to a 4 card setup that is hashing 24/7 built into a large office computer desk. Add a few cheap computer fans and they are happily hashing away around 55-65 degrees Celsius all day, everyday.
There’s a number of cool GPU mining supports that are coming out on .stl and .obj 3D printing file sites. Many of the 3D printed design files are not constructed well enough to support a heavy, $400-800 GPU 24/7 for years. That is the main reason we loved this design – it has excellent support for the PCI-16x riser and there is no wierd pressure on the outside case or power cables. Make sure to check it once you upload to your slicer software for any burrs, errors, and design fails.
We’ve checked out a number of them – tested and broke a handful to pick our current favorite.
3D Printing Specifications:
- PLA or PLA+
- Any color works
- 215-230 Celsius depending on brand
- .2mm layer height
- 80mm/s print speed
- 60 Celsius bed temperature
- 99% infill
- .4mm Nozzle
- Raft only for support
The cleanest upload file we found to work off is on Thingiverse – one of the best 3D file sharing sites online!
Highest quality 3D file upload -> TheInternal – External GPU Stand
- Best layout to support the weight of a 2 or 3 fan graphics card without hurting the card over time
- TONS of airflow around the card for cooling
- No wasted space – design is easy to arrange graphics cards in whatever array is needed for your setup
Tips before printing:
- Double check the hole size in your .stl or .obj – enlarge hole if your GPU has a bigger screw size
- Works great for most AMD and Nvidia cards that do not have oversize heatsinks
- Buy locking nuts and some small washers for the 4mm screw to fully secure and provide maximum stability and support
- Add sticky tape or rubber to the bottom of the mount for less slip
Tip -> buy longer size 4mm screws and add a locking nut on the bottom to greatly help reduce vibration and further secure the GPU!
The GPU can be fixed to the stand with a 4mm tapping screw at the top while the riser PCB is supported at the bottom by the stand’s bottom support beams. I have included a printable pin that should hold the GPU in place, in case you don’t want to or can’t use a screw (untested).– theinternal description on Thingiverse
The 4mm screw size is perfectly matched for our GPU’s but you may want to get longer screws and use a locking nut on the bottom. This helped secure our GPUs for as many days as we need and less vibration through the mount.
There’s always free software like Tinkercad if you want to adjust and manipulate publicly shared 3D files for your own needs.
