DIN rail mount for DC power supply

thingiverse

If there's a piece of furniture under your TV, which tends to be a hub for all the living room electronics, you might like to mount a DIN rail on the back of it to hold all the power supplies for the cable box, amplifier, music streaming box, wifi access point, etc. This piece is a holder for an inline switching power supply held vertically, with cross-section dimensions 52 x 32 mm. You can customize the dimensions for yours. You can use an M3 bolt to clamp the lower clip in place if you are worried about it falling off, but it holds pretty well without it. Print Settings Printer: AIO Zeus Rafts: No Supports: No Resolution: 0.2mm Infill: 15% Notes: I didn't need any support material, but my printer is really good at bridging across gaps. It makes fine strands directly across the gap, which don't sag; but since the gap is so large, the next layer has a tendency to make it sag; so I was standing there with a screwdriver, rubbing back and forth across the underside of the bridge (inside of the pocket) while it printed that layer. The screwdriver shaft absorbs some heat and makes the plastic harden a bit faster. I think it should really be printed on its side, as designed, to avoid delamination of the rail clamp while it's hanging on the rail. If you skimp on infill, you should have enough shells to compensate, so that the pocket itself is solid and only the DIN clip is partially hollow. How I Designed This The DIN clip is from http://www.thingiverse.com/thing:101024 but now it's converted to an OpenSCAD extruded polygon instead of relying on a separate DXF file. I made it with a little bigger opening though, where it clamps onto the rail. Not sure if it was made too tight in the first place, or it's just the tendency of my printer to make all "holes" and inside dimensions a little too small.
