### A parametric 3d-printable mini rack system
|
|
- ***Mount Anything:*** Perfect for organizing SBCs, mini PCs, small switches, power hubs, etc.
|
|
- ***Fully customizable:*** Fully written in OpenSCAD. Everything, from the dimensions of the rack, to the roundness of the corners, can be modified with a simple code change.
|
|
- ***Printable from home:*** Designed to be printed with conventional FDM printers. Requires minimal supports when printing, and final assembly needs only a few easy-to-source parts.
|
|
- ***No cage nuts!*** Sliding hex nut design for the front rails allows one to easily mount items without dealing with cage nuts.
|
|
- ***Stackable:*** Individual racks can be easily stacked and fastened together. Mix and match different color and design combinations!
|

|
## Assembly
|
|
|
|
Pre-generated STLs for roughly 200mm^3 (mini), 180mm^3 (micro), and 100mm^3 (nano) rack frames can be found in [stl](stl).
|
|
These STLs are generated from the files in [rack/print](rack/print), and [rack-mount/print](rack-mount/print) - further information about printing these parts
|
|
(supports, orientation) can be found in these files.
|
|
|
|
### Assembly Instructions
|
|
Please see [the assembly README here](./assembly-guide)
|
|
|
|
### Required Tools:
|
|
- 3d FDM Printer - build size requirements depend on configured rack profile
|
|
- M3 Allen Key (for constructing the rack)
|
|
- M4 Allen Key (for mounting rack-mount items)
|
|
|

#### Notes:
|
|
|
|
- Omitted actual plastic for printing. Any conventional 3d printing plastic should do (PLA, PETG, ABS),
|
|
but beware of PLA's thermal limits. Higher infill is recommended for all parts.
|
|
- For joining two racks, you will need to print 4 [stackConnectorDuals](./rack/print/stackConnectorDual_P.scad), as well as 8 M3 hex nuts, and 8 M3x12 FHCS.
|
|
- Main front rails use M4 hex nuts and screws.
|
|
- Side rails are mounted using M3 hex nuts and screws.
|
|

## Configuring + Generating STLs
|
|
A python script: [rbuild.py](./rbuild.py) is provided to generate different project stls.
|
|
|
|
Requirements:
|
|
- `openscad` cli (Currently only supported on Linux/Mac). Please configure the path to the OpenSCAD binary in [rbuild.py](./rbuild.py)
|
|
- `python3`
|
|
|
|
### Examples:
|
|
Generate all project files for the `micro` profile:
|
|
|
|
`python3 rbuild.py -b all -c micro`
|
|
|
|
This will build all the required STLs for a micro rack in the `stl/custom/` directory.
|
|
|
|
For generating a specific part:
|
|
|
|
`python3 rbuild.py -b yBar -c micro -t custom`
|
|
|
|
Generated stls are put into the `stl/` directories. The actual variable values for different profiles can be found in
|
|
[rack/profiles.scad](config/rackFrame.scad).
|
|
|
|
`rbuild.py` also support an optional `--nightly` flag, which means the build script will use the `openscad-nightly` command, instead of `openscad`.
|
|
|
|
We recommend you start by printing the `eval_P.stl` file first, just to determine if the default slack/layer height
|
|
configurations work for you. If parts are too tight/loose please take a look at
|
|
[config/slack.scad](config/slack.scad). Please also adjust [config/printing.scad](config/slicer.scad) to match your
|
|
slicer settings. |
