rackstack
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), 170mm^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
- M4 Allen Key
BOM - Single Rack:
| Item | Name | Quantity | Comment |
|---|---|---|---|
 |
M3x12 FHCS | 20 | Spares 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:
openscadcli command (Only runs on Linux)python3
Examples:
Generate all project files for the mini profile:
python3 rbuild.py -b all -c micro
Generate specific part:
python3 rbuild.py -b yBar
Generated stls are put into the stl/ directories. The actual variable values for different profiles can be found in
rack/profiles.scad.
