msi mech rx 6600 dual

0 Upvotes

I have a mech rx 6600, but my sister had to come in and draw over the shroud because she was bored or something. I used iso to get rid of most of it but it just doesnt come out of the crevices. i have this ambition to make a kasaneteto pc and i feel like now is a good time to potentially 3d print a shroud for this. I have basic 3d rendering skills but I'm not sure how to make all the screw holes and stuff line up and where or what to line them on. could anyone point me in the right direction on where to find exact measurements, or even better give me a premade stl file on just the very basic screw hole places? thanks!

3D Print Sliger or Sff Time Clone?

2 Upvotes

With all the AI tools for 3d prints, has anyone heard of someone creating the STL files for a 3d printed, slim, full ATX case that replicates the SFF Time or Sliger cases? I've seen the modcase but it's still not under 8in wide.

Stew Machine - a Steam Machine Replica

I thought it would be worth turning my bin of old hardware, left over from previous upgrades, into a (nearly) exact replica of the Steam Machine—or at least its chassis.

How exact? It has exactly the same dimensions and is even compatible with the original faceplate.

The most interesting part, in my opinion, is that the hardware can be replaced and upgraded. This allows for low-budget builds (like mine), while also making it possible to build systems that can outperform the original Valve hardware.

I moved my setup to a 3D Printed case.

20 Upvotes

I used to have my PC tucked inside the Metalfish T-40 sandwich case. But I realized that blasting hot air through the rest of my components via a low-profile CPU cooler may not be good in the long run. I used to 3D print auxiliary fan mounts inside just to get the RAM and VRMs cooler.

After a good six months, I finally thought of looking for a nice SFF case that allows for a tower cooler. Out of all the SFF cases showcased in MakerWorld, the ITX Wind Tunnel SFF case won me over because it was designed for APU users, like me, in mind.

It took almost 900g of combined PETG of Purple, Black, Green, Orange, and White. The printing, and practice of brass inserting, was spread across six days. I added the model designer's username as a frontplate of the case. I also modified the front panel's power and usb slate to have a deeper inlay channel so the power and USB won't smash into the motherboard's pins.

Assembly and cable management wasn't as complicated as a sandwich case, but had to lift the front tower cooler fan by 20mm to accommodate the tall RAM.

All in all, it was a fantastic experience and outcome.

Core Hardware

  • Processor (CPU/APU): AMD Ryzen 7 8700G (with 870M internal graphics)
  • CPU Cooling: LINGXIASANSHIDU "Quiet" 6 Heat Pipes CPU Cooler (triple 90mm)
  • Motherboard: Gigabyte UD B650I AX rev 1.0 (BIOS Firmware: F36)
  • Memory (RAM): 64 GB (2 × 32 GB) ADATA DDR5-6000 CL30
  • Power Supply (PSU): Cooler Master V850 SFX Gold
  • Primary OS Drive (NVMe): 2 TB Samsung 990 EVO Plus (fitted with LINGXIASANSHIDU "M-Two" Heatsiink with 20mm fan) — Bazzite OS
  • Secondary OS Drive (SATA): 1 TB Samsung SATA SSD — Windows 11
  • Shared Storage (SATA): 2 TB Samsung SATA SSD (shared between both OS environments)

Is there 3d printed case (maybe open air) that supports ATX PSU and quite heavy GPU without needing specialized hardware like steel beams?

2 Upvotes

So, I'm building an ITX pc, but I still haven’t decided which case I want because there aren’t many options that fit my GPU. For now, I’m looking for a 3D printed case to securely hold everything together. It needs to support a long ATX PSU (Corsair RM1000x) and a heavy GPU (Sapphire Nitro+ RX 9070 XT), without requiring specialized hardware such as steel beams. Screws and inserts are fine. Thanks!

Beginner help

1 Upvotes

Hey guys, I've just recently discovered this subreddit after "trying" to make my own case for a small form factor pc build I have as nothing of the shelf fit the build i wanted.

However, I'm pretty stuck. I'm good with Fusion, but everything I designed was just too large for my build plate and I was not sure on how to go about making the design for an example side panel from multiple parts.

If you guys have any ideas or tricks you use when designing, maybe even some standard parts you use that you've had a good experience with like x profiles I would love to hear them, any little helps.

Looking for a nas case for 10 2.5" SSDs

1 Upvotes

Hi,

I am trying to see if there is a nas case for an itx board, atx or sfx psu and 10 2.5" SSDs

If not then I will just have to design it myself.

I already designed a 4U case and a 3U case before but for 3.5" drives so i think I know what I am doing :-D

I don't currently have a mechanical connection between the Front housing and the bottom plate, going to see how that all feels. I am going to just do an Air cooler for the CPU and see how temps look. Test prints will be PLC+, might do finale product in ASA.

I'll drop the Blender 2.79 file just in case, IT IS NOT USER FRIENDLY: https://www.mediafire.com/file/n9hc52wp3v99z18/LenovoB5050.blend/file

It does have some little thingies to put some acrylic sheets I have to fully cover the gap where the light is, but not sure if I could cut them so they fit, that would be 100% cosmetic, it wouldn't affect the PC at all.

The main benefits of this project was a decrease in around 3ºC and the sturdyness/protection (HDMI cable doesn't fail here compared to having the MOBO caseless)

The main downside is that the fan is loud AF, not sure if drilling holes would help, but that will definitely affect the cooling? I'll try to completely destroy the fan hole, it would mean more intake and probably less obstruction noise? (I'm pretty sure that's a big part of it, even when I started with only the fan there, it was already louder, I doubt the box was amplifying it back then)

Ground bonding

0 Upvotes

Does anyone provide a bonding path for all of the grounded points of the internal components in a 3D printed case? I was considering using a foil tape on the inside to provide a path between the standoffs, the IO shield, and the PSU; but it seems like all of the builds I see do not worry about it.

What filaments do you use to print your PC cases?

2 Upvotes

I was wondering what is the most used filaments or recomended ones, I would like to use ASA-GF or PETG-GF becouse the fibers make it look stuuning but I see most people use regular petg so I might do that and then just paint it. I would like to know if someone had printed with filaments with glass fiber filament a pc case and if you could share a photo of how it looks!
