RETRO GameStack - Sony PSP (UMD Cases) - Parametric FreeCAD

Overview

A fully parametric Sony PSP (UMD Case) edition of Jerrari's RETRO GameStack modular storage system, designed from scratch in FreeCAD with a 100% 0-DOF constrained sketch tree and spreadsheet-driven parameters.

Each Slot tier holds 5 standard Sony PSP UMD game cases (105 mm × 15 mm × 170 mm) with 1.2 mm per-case clearance (16.2 mm bay width, 92.0 mm total external width) and stacks vertically or mounts to the GEN2 rail system using the exact standard GEN2 QuickLocks V1 clips.

Key Features

• 100% Compatible with Standard GEN2 QuickLocks V1: Uses the exact dual-tapered front locking slits and enclosed 6.00 mm outer side walls from the original RETRO GameStack so standard GEN2 QuickLock clips snap in flush with zero outer wall opening.

• Support-Free Printable Geometry: Features a solid bridged rear floor section, 45° self-supporting rear window cutouts, and 45° inner/outer side wall recesses so every part prints cleanly without supports.

• Flush Multi-Tier Stacking: Top tongue rails and bottom mating channels include matched clearances so multiple PSP slots stack and slide all the way to the rear stop seamlessly, crowned with the top Cover cap and supported on the bottom by the Foot Rails (with optional TPU Feet).

• Fully Parametric FreeCAD Source Included (.FCStd): Includes the complete multi-body master FreeCAD project (RETRO_GameStack_Sony_PSP_Complete.fcstd) with a centralized Params spreadsheet—change case_thickness, case_depth, or slot_count to adapt the stack to other media cases automatically.
