RatRig V-Minion Meanwell UHP-350-24 + RS-25-5 Mount

prusaprinters

<p>Based on the Original Model by JP3d<br><br>Added space for an additional 5V (Meanwell RS-25-5) Power Supply on top of the Meanwell UHP-350-24 since I wanted a separate PSU for the finnicky Pi4.<br>The Cap on the opposite end where the wires of the UHP go out was modified so you can pull the 5V wires along the original ones.</p><p>The Mounting-Arm is not altered, you need 2 of those. I recommend to print one x-mirrored for symmetry, but suit your needs of course =)<br><br>WORD OF WARNING:<br>After printing and assembling this whole thing, i just have to say that the Cap with the Switch is a bad design by nature. The SINGLE mounting screw for the UHP connects to a part which just falls off inside the PSU with no chance of afixing it so you can fasten it when its in the Cap. I had to use Hot-Glue to fixate the Mount inside the PSU, but ofc a single M3 Screw on one side is just not enough to hold this rigidly.&nbsp;<br><br>The Hex Inserts are also problematic, since when you screw the Switch on, you most likely will have your (short) wires already attached, and thus it's hard to reach them. For a future design, Heat Inserts would be the way to go.<br><br>The single fastening screw for the RS PSU works better, but is not an optimal solution either, especially looking forward to the vibrations the Minion can excite. I will test this.<br><br>The Original Arms work perfectly, and the modified endcap with the tunnel is okay, but also not well fastened.<br><br>A complete redesign of the Switch Endcap maybe the best course here.&nbsp;</p>
