iPod Classic 5th Gen USB-C adapter slide-in Case

This project is a design exercise that encloses a 30-pin-to-USB-C adapter in a printed case for the iPod Classic (5th / 5.5th generation, thin). The goal is a reversible way to add USB-C without soldering or opening the iPod.

This revision is a single-piece slide-in shell: the adapter nests in a pocket and the iPod is retained by the case geometry (side rails and bottom cradle). The USB-C port aligns with the original connector area. The case adds ~1 cm to overall length.

Features

• Design exercise, not a finalized product
• Reversible mod; no soldering, no disassembly, no screws
• Uses inexpensive 30-pin-male → USB-C-female adapter block
• Slide-in retention by shape/friction; optional shim ribs for tighter fit
• Adds ~1 cm to the iPod’s length

Assembly

1. Press-fit the 30-pin→USB-C adapter into the internal pocket (USB-C facing the opening).
2. Slide the iPod in from the top until it bottoms out and the side rails capture it.
3. Plug in a USB-C cable and use as normal.
   (Optional) For 6G/7G thin models, add a 0.3–0.6 mm foam/TPU shim or print the ribbed variant for a snug fit.

Print Settings

• Material: PETG or ABS recommended (PLA works)
• Layer height: 0.2 mm
• Infill: 12–20%
• Walls: 2 perimeters
• Orientation: standing up 
• Supports: light supports under the setting top lip/port.

Bill of Materials

• 1 × 30-pin male → USB-C female adapter (generic “white block” style)
• (Optional) Thin foam/TPU tape strips for shimming 6G/7G thin
• 1 × 3D-printed slide-in shell

Notes

• Compatibility: Designed for 5G/5.5G 30 GB thin. Works on 6G/7G thin but those are ~0.5 mm slimmer—use shims or a ribbed variant. Not compatible with 6G 160 GB fat.
• This is a proof-of-concept to validate an external, reversible USB-C enclosure.
• Adapter quality varies: many are charge-only; some allow sync—test your unit.
• Personal use only. Commercial use or resale is prohibited.
