🖤 4TF MkIII – Laser-Cut Precision Meets Printable Power

The 4TF MkIII is a compact, modular mini-ITX case designed for creators who love blending laser cutting with 3D printing. The 4TF is about retaining wide hardware compatibility while upgrading durability, cooling, and customization potential through the use of premium filaments and laser-cut panels.

A super fun use case for the Bambu HD2 + Laser, this project could be done entirely with that machine.

⚙️ Hardware Support:

Motherboard: Mini-ITX
GPU: Low Profile (Half-height)
- Confirmed: NVIDIA A2000, Arc Pro A40/B50, 5060 LP
PSU: FLEX 1U (150–300W)
Cooling: Dual front-mounted 92x15mm fans
Storage: 2.5” SSD support
Other: GPU brace and rear vent structures included

🧠 Design Philosophy:

The 4TF is meant to bridge the gap between accessible DIY and premium SFF craftsmanship. While the 3DLP is an all-printed, entry-friendly design, the 4TF takes things further with support for laser-cut aluminum or acrylic side panels, making it ideal for users who want strength, heat resistance, or hybrid manufacturing workflows.

Even if you’re just printing it entirely in filament, the MkIII version now includes:

🧱 Improved support-less printability
🧲 Tighter kerf-tuned alignment
🔒 Stronger GPU mounting
🧦 Optional printable feet

📦 Files Included:

STL / 3MF for all printed parts
DXF for laser cut panel templates
STEP / F3D (via Patreon for remixing or CNC)
Link to BOM and time/cost spreadsheet

🧩 Recommended Materials:

PETG-CF / PETG-GF – strong, printable, easy to finish
Nylon+CF – premium feel, great for structure
PLA+ – fine for prototyping or display builds, no warping experienced so far.
3mm Acrylic – for side/front panels if laser cutting

Marvelous case design! Thank you, Josh! Here's my build: - front and back: African red sandal tree 5mm thick - top, bottom and MB panels: carbon fiber 3mm thick - cpu cooler side: translucent black plex - noctua fans 92x15 - redid the button a little bit: designed a new front plastic panel to accommodate standard PC switch, made a button for it. Will also make a front cap from the same wood (currently in progress). Printed with Sunlu PETG using P1S. All the side panels are CNC'd specs: - intel alder lake - 32GB Ram - RTX 5060 - FSP FlexGuru 500W, sadly non-modular, so had to be creative with redundant cables :-)

That's gorgeous, great choice of wood too. <3

Hello, I don't have a laser cutter, and I'm not very interested in one. Would you be able and willing to release the other panels as stls so I could just 3d print them? Thank you!

Hey! Yeah, as our other friend here linked, I have a better design for that coming soon. I'm just really busy. :( However if you don't have CAD software and don't want to extrude for printing, then I have the STEP files for this on the OG YouTube video and the Mkiii on the Patreon. I might upload STL files for it all later but...id encourage you to look at the 3DLP first.

@plarry2

Replying to @user_1254130294 :

I do have cad and I am medium competent with it. So the 3DLP files are on your partreon? I might check that out then!

@user_1254130294 do you plan to release the STEP files? I would like to make the side panels (212mm) a few millimeters smaller, since my laser can do a maximum of 210mm

The designer has replied

@user_1254130294

sorry for the late reply. If you go to "download STL/CAD files" you can download the DXF. Any CAD program can extrude the DXF, so you can make it as thick or thin as you want. This is my workflow for the side panels.
