Vỏ PC ATX Mid-Tower TimberCube Rhino | File in + CNC

Hey there! 

This TimberCube R2 case (codename Rhino) is a full-size mid-tower ATX PC case utilizing 3D printed joints, brackets and mounts for your PC hardware. Front, top, rear and bottom panels are made of wood (though feel free to print them too if you'd like to try) and both side panels are glass.
It's equipped with front and top radiator filters, horizontal/vertical (switchable) GPU bracket and removable HDD case for easier installation.

All printable parts have been re-designed to fit on Prusa i3/MK4/CORE One (minimal build area dimensions 250*210 mm (X*Y), it doesn't require much Z).

In case you're struggling with obtaining some below listed parts, wooden panels, glass panels, fasteners and other accessories are available on Etsy:

Purchasable hardware

• 1x I/O panel (2x USB 2.0, two standard audio ports)
• 1x Double-USB 3.0 cable
• 2x Standard Power+Reset motherboard switch
• 2x Metal cylindrical insert with PTFE coating
• 2x Glass panel (360x430 mm)
• 16x 3x5 mm cylindrical neodymium magnet
• 6x 20 mm round foam pad

Front I/O panel has standard audio ports and two USB 2.0 ports. I use this one, purchased in Czech Republic. They're probably buying them from AliExpress. This one looks almost identical.
However, if you want to use a different I/O panel or just need to adjust tolerances, feel free to download and edit its STEP file.

For the USB 3.0 port I use this one. It has two separated USB connectors on one end and a single shared 20-pin connector on the other. I just took off the metal bracket. This AliExpress one should be compatible.

Power and reset MB (motherboard) switches - for example these should fit nicely.

Power and reset buttons (those actual buttons that are mounted to motherboard switches) are laser-cut with engraved power/reset symbols. They are inserted in printed casings. As these casings made quite a lot of noise rubbing against printer button panel, I use metal inserts with PTFE-coated interior. Those are not mandatory, but nice to have. I use this one for power button and this one for reset button. If you can't obtain them locally, I'm sure that just a simple plastic injection molded hollow cylinder would work too, though it would have to have the right dimensions, but again, it's not necessary to have.

Glass panels are made of 4 mm thick glass. Both panels need precise dimensions of 360x430 mm. Right glass panel has black coating.

The 3x5 mm cylindrical neodymium magnets shouldn't be hard to get, I found some here for example.

And lastly you might need the 20 mm round foam pads so the case doesn't scratch your table. These pads are standardly used for chairs. Again, I obtained them locally, but they should be easy to get.

CNC+Laser instructions

For wooden panels I use 15 mm thick European beech wood. All geometry can be cut with a 6 mm Flat Endmill. Corners were designed to minimize bit friction. There are embedded printed M4 nut adapters and feet in the wooden panels, which have a nice, snug fit. It's possible that these tolerances won't work well for your setup. Feel free to adjust offsets in available STEP files.

The only laser-cut parts are both power and reset button inserts (with engraved symbols) for which I used 8 mm thick wooden board. Feel free to 3D print these inserts if you don't have a laser.

For engraving and cutting I use xTool D1 Pro 20W. Engraving at 60% power at 80 mm/s, 250 lines per mm. Cutting at 100% power at 6 mm/s, 4 passes. These settings vary greatly based on your machine and wood used.

Print instructions

Use at least PETG. I do not recommend using PLA due to its low temperature resistance. All parts are tested with Prusa MK4, 0.4 mm nozzle and IS 0.2 mm SPEED print profile. I use solely Prusament PETG and therefore its default filament profile as well. 
Prepare at least 1.3 kg of filament.

I designed as many parts as possible support-free except for:

• All glass covers
• GPU adapter - Inner

In the assembly manual you'll find pictures where to place supports, so I recommend reading the Before you begin chapter before you start printing.

Fan filters and fan holders have embedded magnets. You'll find more information on how to print them in the assembly manual.

And that's it! If you find this design valuable and would like to see more in the future, I'd really appreciate your support at Buy Me A Coffee https://coff.ee/jemmorai which will help me keep at it :) Thanks!
