LM2596 Enclosure set (real screwless fit )

thingiverse

After several dissappointing LM2596 Covering boxes made, I have decided to design myself a cover box by measuring my already bought LM2596 modules. If needed, see below the actual link I bought it from, but I'm sure there are similar ones available. https://de.aliexpress.com/item/4000764110631.html?spm=a2g0s.9042311.0.0.26ce4c4d5y7wTa What was the task for me: - Exact fit if possible without inserts and screws. - Knobs for Mode and Voltage regulation. - LCD Display visible - Openings for the IN and Output connections to be reachable anytime. - Some air openings and filament savings on the cover bottom. It took me quite some time to measure all the needed details and still to result in some good and nice design. I was surprised myself how good this enclosure after some tests fits my tasks. The LM2596 fits tight without screws into the Cover bottom and the Cover top slides perfect over the 4 bottom pins. Build instructions: - Print all 4 parts in your prefered color. - Put your LM2596 into the Cover bottom. - Place the Voltage Bottom onto the LS2596 module and slide the Cover top over the module to close the Module Box. ( Maybe first to place the Mode knob trough the top hole for the Mode selection.) - Click the Perimeter knob carefully through the perimeter hole into the adjustment screw of the LM2596 module. ( If wanted you can handle it also without the perimeter knob in place with a small screw driver through the perimeter opening ) If all works fine you can glue top and bottom together, but not really needed because the parts are fitting really well and I use it without glue. I have added all stl files and Gcode files for your reference. See also pictures from my build and finish. Feel free to use it without any restrictions. - Please measure your LM2596 module precisely before you start printing. - The build is so precise that it only fit for this dimensions on the modules above. - The 4 pin whole distance middle to middle is 57.5 x 31.5 mm. - The LM2596 Module size is LxB 65 x 39 mm - Cover Box outer dimensions = LxBxH 68.4 x 42.4 x 18.4 mm Wall thikness 1.6mm - !! The dimension drawing on the AliExpress side is incorrect !! - Delivery from AliExpress is with different dimension like mentioned above. - The centre of the perimeter whole is 29 x 6 mm from the right and top of my enclosure box. Remark on 25.01.2021 I have found a similar design of the LM2596 DC-DC module at Amazon showing my measured dimensions in their specification of approx 65 x 39 x 18 mm. See the link below without any guaranty for 100% fit but looks promising. https://www.amazon.de/gp/product/B081N6WWJS/ref=ox_sc_act_image_1?smid=A3FQVMQEQ9LI6F&psc=1 Have fun building up a well sitting screwless LM2596 Cover box.
