Spring-Loaded 35mm DIN Rail Clip (Print-in-Place Latch)

A robust, mechanical 35mm DIN rail mounting bracket designed for secure, quick-release installation of enclosures, PCBs, and custom hardware inside electrical cabinets. Unlike friction-fit plastic clips that fatigue and snap over time, this design uses a captive sliding latch backed by a metal compression spring for positive locking and easy removal. Key Features: - Positive Spring-Loaded Lock: Uses a standard coil spring to keep firm tension on the 35mm DIN rail, preventing vibration loosening while allowing tool-free release.

- Captive Sliding Latch: Guided dovetail/stepped track keeps the moving locking tab captured cleanly inside the main body.

- Flush Mounting: Two recessed screw holes allow secure attachment to the back of any project box or mounting plate without interfering with the DIN rail.

Bill of Materials (BOM): - 1x Compression spring: 16 mm length × 6 mm outer diameter

- 2x M3 bolt

- Distance between bolt holes is 23 mm

Print & Assembly Instructions: - Material: PETG, ASA, or ABS recommended for electrical cabinet heat resistance and smooth sliding action.

- Layer Height: 0.2 mm

- Supports: None required (orient flat on the print bed).

- Assembly: If printed as a print-in-place assembly, gently break the slider loose after printing, compress the 16×6 mm spring into the rear pocket, and cycle the latch a few times to smooth the sliding surfaces.
