DIN Rail - top hat rail IEC/EN 60715 – 35 × 7.5

This print was the result of discussions about the use of DIN rail with 3D printed parts within the following group:

3d Printing for Metalworkers and Model Engineers

Admittedly this print is of limited usefulness for the following reason:

• Actual DIN rail is inexpensive
• Actual DIN rail is metal, and conductivity is a requirement for some applications
• The plastic version is of course not as strong as the metal version

However, this print may be of some use for test purposes, or when small quantities of DIN rail not requiring high strength are needed.

The prints provided here are all based on an initial “unit” of rail 25mm in length, with additional lengths based on multiples of this unit.

The OnShape 3D CAD files for this are here :

Print Instructions

Print in PLA using the 3mf files provided; note that a brim is required for adequate bed adhesion.

In order to print with no supports, and with the filament in the ideal orientation, the rails are printed “end down.”  I was frankly surprised that this worked well even with the “8 unit” print fully 200mm high (see photos).
