Modular Vinyl Record and CD Holder

Modular Vinyl, 45, and CD Holder System – 5-Part Expandable Design

This is a modular media-storage system designed to organize and display your music collection with customizable length and layout. The model includes five unique components that can be combined to create the perfect holder for LPs, 7" (45) singles, and CDs. Print new modular parts as your collection grows.

This is the fourth version of this year long project to create a holder for my LPs, CDs and 7 inch singles; this is the final design.

Use the manual supports I added for easiest support removal!
