Sensata Crydom ED24D5R relay mount (CC-BY-NC-SA)

Mount for the Sensata Crydom SSR ED24D5R. ## Why I didn't want to buy a cheap Fotek knock-off SSR because I feared malfunction. Even if only 3.4A go into a Meanwell LRS-350-24, I'd rather be safe. I found this relay at the local electronics store. But I wasn't aware that it was so tiny. It also didn't come with a way to mount it. There's a THT socket and DIN rail socket available to buy but I didn't want to use them. Mainly because they will impede with how I want to use the relay The intended use of this relay is as a cut-off device for the line wire of my printer's 24V PSU. ## Design Details Holds the relay flat on the side. The nose on the relay and the notches on the underside prevent the SSR from slipping out and keep it in place. Since the nose on the SSR is at the same position for the 3A version, I'm quite confident that it will fit that version as well, but I haven't tested it. Made to fit the relay with the LED facing up. Not tested with the LED facing down. If you need it in LED facing down, mirror the Thing in your slicer. Mirroring is necessary because the underside of the relay is asymmetrical. But if you use this with the LED facing up, then all the text is still visible. There are a few versions: - without hole - center hole for M3 counter-sunk screw - double hole for M3 counter-sunk screw The plate on the holder is so thin that it might be easier in some cases to drill the hole after printing. I tried to make the holes to fit a sunk-head screw. But the base plate of this holder is only 2mm, it can only fit a M3 screw. If needed, I can also make different holes for M4 and M5 counter-sunk screws. But that would make the base plate bigger. Just tell me if you need other versions :) . There are also a few versions with a flap for M3, M4, M5 screw in case you don't have a counter-sunk screw. The blade connectors on the relay need 4.8mm terminal connectors. Keep in mind if you consider buying this SSR. Modelled for the solid state relay ED24D5R. Might also fit the relay types ED06B5, ED06C5, ED06D5, ED06E5, ED06F5, ED10C10, ED10C5, ED10D10, ED10D5, ED10E5, ED10F5, ED24B5, ED24B5R, ED24C1, ED24C1R, ED24C3, ED24C3R, ED24C5, ED24C5R, ED24D3, ED24D3R, ED24D5, ED24E5, ED24E5R, ED24F3. Please refer to the [official Sensata Crydom website](https://www.sensata.com/products/relays/plugin-mount-ac-dc-output-ssrs/ed-series) for an official dummy model of these relays and an official datasheet. Those are available in STEP and DWG format. I tried to import the STEP file into FreeCAD but I can't get a solid model to print. ##Print Instructions Maybe consider using a nozzle of size 0.2mm because this holder is very small. I used a 0.4mm nozzle and it came out ok. Print upright to give the holder arms more strength. Print like shown in screenshot Use supports. Use brim. Print in 100% infill. ##Materials needed - knife to remove support and brim. - (optional) drill in appropriate size if different size hole is needed. - (optional) tap if thread in hole is needed. ##Assembly Instructions <ol> <li>Print Thing <li>Remove supports and brim with knife. Make the edges of the little notches smooth and straight. <li> (optional) Drill hole into base plate <li> (optional) Make thread into hole <li> Mount holder with screw on where it has to go. </ol> (All product links are MakerBot affiliate links.
