DIN Rail Mount SMPS Power Supply (120x80mm)

Description:

This is a reliable two-piece mounting system designed to easily attach an SMPS power supply to a standard DIN rail. The modular design allows for fast, support-free printing and a solid assembly, making it perfect for organizing electrical panels, 3D printers, or automation projects.

The base plate is compatible with SMPS units that have a 120 x 80 mm mounting hole spacing.

3D Printed Components:

• Base Plate: The main "X" shaped part that attaches directly to the back of the SMPS.
• DIN Clip: The mount that attaches to the base, featuring integrated flexible arms for a firm and secure grip on the DIN rail.

Bill of Materials (BOM):

To fully assemble this mount, you will need the following hardware in addition to the printed parts:

• 4 x M3x6 screws — to secure the printed base plate to the metal casing of the SMPS.
• 2 x M3x8 screws — to attach the DIN clip to the base plate.
• 2 x M3 nuts — to secure the two printed parts together (base plate and DIN clip).

Assembly Instructions:

1. Insert the 2 M3 nuts into the dedicated hex slots on the base plate.
2. Place the DIN clip over the base plate and align the center mounting holes.
3. Secure the two parts together using the 2 M3x8 screws.
4. Align the assembled mount with the threaded holes on the back of the SMPS (120x80 mm spacing).
5. Screw the base assembly to the power supply using the 4 M3x6 screws.
6. Snap the power supply onto your DIN rail!

Recommended Print Settings:

• Material: PETG, ABS, or ASA. These are highly recommended because power supplies generate heat, and these materials offer superior thermal resistance. PLA can work if the area is very well ventilated.
• Infill: 20% - 40% (to ensure the mechanical rigidity needed to hold the weight of the power supply over time).
• Supports: No (the parts are designed to be printed flat on the build plate).
