A More User-Friendly 1-to-4 Splitter

[Open Source Project] An Enhanced 1-to-4 Splitter

This project is designed for the most prevalent and affordable commercially available DTAP 1-to-4 splitter (pictured), with all models offering non-destructive modifications replacing the original baseplate

Replacement Baseplates

Mark0 Original Baseplate

Essentially identical in dimensions and appearance to the original, the model is streamlined for ease of modification by subsequent developers
Recommended basic hardware: M2.5*8 countersunk screws
(All versions utilize basic hardware)

Mark1 Dual-Screw Baseplate

Securely fastened with basic hardware and any two 1/4\" screws; using self-tapping screws prevents loss. Maximum distance between fixing screws is 25mm, offering two symmetrical mounting orientations; consider minimizing footprint on the kit's space

Mark2 Single-Screw Baseplate

The single-screw design incorporates anti-rotation features with precisely located mounting holes, and uses a specific 1/4\" screw. A design detail: 3*8mm cylindrical positioning pins create an interference fit with the printed part, acting as anti-rotation locators, spaced 15mm apart. This approach is suitable for various anti-rotation applications, and the pins can be removed with pliers.

Mark3 NPF Baseplate

Provides models with two cable exit orientations; the only baseplate model requiring supports, it also utilizes only basic hardware for fastening—the advantage being that no screws need to be tightened. It can be installed on devices with an NPF back panel for power supply, allowing for a customized shorter power cord. A design limitation is its current “cold connection” nature, lacking an elegant and reliable solution for use as a dummy NPF battery

A Personal Note: Other 1-to-4 Splitter Configurations

Extending from the baseplate, the 1-to-4 splitter is integrated as a module into other projects. For example, a 1-to-4 splitter incorporating a voltmeter module, or wireless versions with various sockets
