<p>Lab bench power supply based on <a href="https://www.thingiverse.com/thing:3831773">https://www.thingiverse.com/thing:3831773</a><br/>But since I didn't need all the features and I wanted a different design, less features but even more compact!</p><p>Bill of materials in pdf format<br/>Pack and go available in SW2019 format<br/>STEP available</p><p>Power supply hole pattern may be different, I adjusted it after making mine. I dremeled the PCB to fit.</p><p><a href="https://www.ebay.com/itm/High-Power-AC-DC-Converter-110V-220V-230V-to-36V-5A-180W-Switching-Power-Supply/123275121813?ssPageName=STRK%3AMEBIDX%3AIT&amp;_trksid=p2057872.m2749.l2649">https://www.ebay.com/itm/High-Power-AC-DC-Converter-110V-220V-230V-to-36V-5A-180W-Switching-Power-Supply/123275121813?ssPageName=STRK%3AMEBIDX%3AIT&amp;\_trksid=p2057872.m2749.l2649</a></p><p><a href="https://www.ebay.com/itm/DC-DC-Buck-Step-down-5V-36V-to-3-3V-6V-9V-12V-24V-5A-Converter-Voltage-Regulator/272834659085?ssPageName=STRK%3AMEBIDX%3AIT&amp;_trksid=p2057872.m2749.l2648">https://www.ebay.com/itm/DC-DC-Buck-Step-down-5V-36V-to-3-3V-6V-9V-12V-24V-5A-Converter-Voltage-Regulator/272834659085?ssPageName=STRK%3AMEBIDX%3AIT&amp;\_trksid=p2057872.m2749.l2648</a> Stuck down with double sided tape</p><p><a href="https://www.ebay.com/itm/DP50V5A-Digital-LCD-Display-Voltage-Programmable-Step-Down-Power-Supply-Module/163645634693?ssPageName=STRK%3AMEBIDX%3AIT&amp;_trksid=p2057872.m2749.l2649">https://www.ebay.com/itm/DP50V5A-Digital-LCD-Display-Voltage-Programmable-Step-Down-Power-Supply-Module/163645634693?ssPageName=STRK%3AMEBIDX%3AIT&amp;\_trksid=p2057872.m2749.l2649</a></p><p><a href="https://www.ebay.com/itm/10Pcs-Speaker-Terminal-Binding-Post-For-4mm-Banana-Plug-Socket-Female-Connector/142631918119?ssPageName=STRK%3AMEBIDX%3AIT&amp;_trksid=p2057872.m2749.l2649">https://www.ebay.com/itm/10Pcs-Speaker-Terminal-Binding-Post-For-4mm-Banana-Plug-Socket-Female-Connector/142631918119?ssPageName=STRK%3AMEBIDX%3AIT&amp;\_trksid=p2057872.m2749.l2649</a></p><p><a href="https://www.ebay.com/itm/12V-DC-80x10mm-Brushless-2-Pin-Cooling-Fan-LED-Heatsink-Marine-PC-CPU/193044009715?ssPageName=STRK%3AMEBIDX%3AIT&amp;_trksid=p2057872.m2749.l2649">https://www.ebay.com/itm/12V-DC-80x10mm-Brushless-2-Pin-Cooling-Fan-LED-Heatsink-Marine-PC-CPU/193044009715?ssPageName=STRK%3AMEBIDX%3AIT&amp;\_trksid=p2057872.m2749.l2649</a></p><p>2020-01-19 Update:<br/>Added individual STL files, thanks rpt007</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p> </p><p><strong>Printer: </strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p> </p><p>No</p><p> </p><p><strong>Supports: </strong></p><p>No</p><p><strong>Resolution:</strong></p><p> </p><p>0.2</p><p> </p><p><strong>Infill: </strong></p><p>whatever</p><p><br/><strong>Filament:</strong><br/><br/>Prusament PETG light grey and orange <br/> </p><p><strong>Notes: </strong></p><p>.3mf available</p><p>See print bed layout for orientation</p><p> </p><h3>Post-Printing</h3><p>This is at your own risc.
