HomeRacker - Core

Help me overengineer more stuff if you like this one!
A fully modular universal rack building system for virtually any "racking needs" (Server Rack, bookshelf, shoe rack, you name it).
HomeRacker grows with your needs — start with a small Pi-Rack and scale up to 10" or even 19" racks. Multiple racks can be assembled together. There are no limits to how big you want to build.
Check out this Cyberpunk-themed 10" Rack — a perfect showcase of what HomeRacker can do.
📦 What's in the Box?
This model contains the core parts of HomeRacker:
- Supports — from x2 to x17 in the print profile, customizable up to x100
- Connectors — all permutations, sane defaults in the print profile
- Lock Pins — standard, extended grip, and neck extension variants
- Foot Inserts — snap into any connector arm for stability and grip (also available as a standalone model)
- Diagonal Supports — stabilizers for load bearing or large builds (separate 3mf folder)
All parts are fully customizable in the Parametric Model Maker (v1.8.0+).
🙅♂️ Do NOT autorotate the parts! 🙅♂️
No part needs printing-supports when exported from the Model Maker (provided you didn't deactivate optimal_orientation). Print single-holed supports with the hole aligned vertically for best locking experience.
Diagonal Supports
Stabilizers for load bearing or large builds. 5 permutations to cover many directions, in almost any printable size. Available as 3mf files in the "Diagonal Supports" folder.
