3D Printed Rack Parts

Filling gaps in the rack build with printed parts — ears, blanks, and a modular tray system. Mix of sourced models from Printables and geometry scripted in Blender Python.

Sourced Models

Model	What it is	Status
1U Universal Rack Ears	Rack ears for gear that ships without them	Printed
1U–4U Spacer / Blank Panel	Blank panels to fill empty rack units	Printed
RackMod 1U Slide-A	Modular 1U tray system with slide-in modules	Testing
19" 1U/2U/3U Cover Plates	Solid cover/blanking plates for 19" rack	Queued
1U Rack Cable Ears	Rack ears with integrated cable management	Queued
Raspberry Pi 1U rack mount	1U mount for RPi in 19" rack (BIFROST)	Printed
Zip Tie Clip 45mm T-Slot	Cable management clips for 45mm extrusion	Queued

Scripted Parts

Geometry generated by a Python script running inside Blender rather than modeled by hand. The immediate need was a support brace for the rack — a 220×150×8mm plate with 40 through-holes in a specific alternating-spacing pattern, the B.E.S.T label engraved into the top face, exported directly to STL.

Writing it in Python means the layout lives in a config block at the top of the file. Changing hole count, plate dimensions, or row spacing is a constant, not a modeling operation.
