Soldering Iron Power Supply

thingiverse

Working in the IT industry gives me access to often surplus and unneeded tech. This tech is not necessarily out-of-date, but technology changes or things like brand alignment has changes. This tech is often discarded. The Lenovo 65W power pack is an example of a piece of tech that is still useful for other purposes. I have redeployed a Lenovo power pack as a power supply for my Weller bench soldering iron. With a buck inverter, I boost the power pack 20V output to 30V for the Weller iron to drive the iron at 40W. To enclose the power supply, I designed a custom 3D printed case. The case houses the power pack, the buck inverter, a socket for the soldering iron and a push button power switch. To make the print result more interesting, I do a filament colour swap near the end so that the raised text is printed in another colour and make it more visible. The filament colour swap is setup in your slicer software. Setting up the filament colour is easy in PrusaSlicer, other slicers probably, too. My print is made in PETG 1.75mm Aurarum silver and 3DFillies black filaments, with 0.2mm layer height and 100% infill on a PRUSA I3 MK3S printer. I hope you can find this print useful, too.
