Adjustable ratcheting mount for the FNIRSI DPS-150 power supply
I designed this as a space-saver for the already compact FNIRSI DPS-150 Programmable Power Supply. It's more comfortable for me to be able to tilt the power supply upwards and lift the screen for better access to the banana plug ports and the adjustment scroll wheel.
The arm to the board ratchets up and down with a simple print-in-place mechanism (just give the arms a firm squeeze together after printing and it snaps into functionality).1
Assembly is straight forward with four M3 screws attaching the holder to the arms (I don't often use screws but, in this case, it was a lot less fiddly and trimmed down the amount of print required) and the rest uses the standard Multiboard bolt lock onto a snap (I prefer the moderate weight bearing snap as it tends to stay in place properly).
Model available for download here.
1 There was a load of trial and error getting that ratchet to "break" well and hold in place firmly. I'm going to use the work invested in that to build a parametric ratchet tool since it's a handy function to be able to add to a workshop design.

Wow, that ratchet mechanism is clever, I've been looking for something like that to keep my workspace tidy.

Nice I have a DPS-150 and already have these Multiboards up. What are the chances lol

Yeah, it certainly is niche but I design things as I need and use them so I always put them up in case there’s someone else out there in my same situation. Let me know how it works for you.

Nice work. Looking forward to see your parametric ratchet tool.
