The author remixed this model.
This is a remix of DIN clips for Meanwell LRS 200 PSU by neon.blue that I made to allow the PSU to so slightly slide to accommodate for differences in DIN spacing and also better fit in tight electronics compartments. It gives about 13mm of travel and will still need 4x M4 x 6mm BHCS to install the PSU.
Thanks again to neon.blue for the original design.
