Lily58 MX Case Set – Compatible with PandaKB Lily58 & Lily58 Pro

A 3D-printable case set for the Lily58 MX, a popular 58-key split ergonomic mechanical keyboard.

This case was originally designed for the PandaKB Lily58 MX, but it is also compatible with standard open-source Lily58 Pro MX builds that use the same PCB outline and mounting-hole layout.

The design includes separate left and right switch plates and bottom cases, making it suitable for both wired and wireless Lily58 builds.

Included 3D-Printed Parts

- Left MX switch plate
- Right MX switch plate
- Left bottom case
- Right bottom case

Compatibility

Designed for:

- PandaKB Lily58 MX
- Standard Lily58 Pro MX
- Cherry MX-style switches and compatible MX switches
- Wired builds
- Wireless / ZMK builds

This version is designed for the MX switch layout and is not intended for Choc low-profile switches.

Please note that Lily58-compatible PCBs from different manufacturers may have small differences in PCB outline, mounting-hole locations, or component placement. If you are using a modified or non-standard Lily58 PCB, check the dimensions before printing.

Required Hardware

To assemble both keyboard halves, you will need:

- 16 × M2 × 4 mm countersunk screws
- 8 × M2 × 6 mm standoffs

The M2 × 6 mm dimension refers to the standoff height.

These parts are used to secure the switch plates and bottom cases together.

Display Covers

The display covers are designed to be made from acrylic.

Wireless Builds

This case can also be used for wireless Lily58 builds.

This version does not include a dedicated battery compartment in the bottom case.

For wireless builds, it is intended to be used with a compact 301330 LiPo battery, installed in the available space between the MCU module and the main keyboard PCB.

Because there is no battery pocket in the bottom case, larger LiPo batteries may not fit.

A separate version with a dedicated battery compartment in the bottom case may be released in the future.
