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. These STLs are generated from the files in rack/print, and 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

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)

BOM - Single Rack:

Name	Quantity	Comment
M3x12 FHCS	20	Extras are useful and inexpensive. If you plan on eventually stacking multiple racks together, don't hesitate to get a lot more.
M3x16 FHCS	16	☝️
M3 hex nut	36	☝️
3x10 steel dowel pin	4	3mm diameter, 10mm height
6x2 neodymium disc magnet	8	6mm diameter, 2mm height
super glue	>= 2ml	Used to glue magnets to plastic

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 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 is provided to generate different project stls.

Requirements:

openscad cli command (Only runs on Linux)
python3

Examples:

Generate all project files for the micro profile:

python3 rbuild.py -b all --nightly -c micro

This will build all the required STLs for a micro rack in the stl/custom/ directory. The --nightly is optional and means the build script will use the openscad-nightly command, instead of openscad. This usually results in much faster build times and is generally recommended.

For generating a specific part:

python3 rbuild.py -b yBar --nightly -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.
