I am a big fan of the BTT UPS 24V. I run this little guy on all of my printers. It is small. It puts an end to lost prints from power failures. On my Big Red IDEX I have mounted the UPS directly behind the tft35 v3.0 display..



When we think about wattage and 3d printer heated beds and high temp extruder heaters and just the size or time some of these prints can take it is just not logical or realistic to try to keep a printer going off of battery power in a power outage. This really is the smart way. Save your place, pick the nozzle up off the print and just hold. I mounted the BTT UPS for this printer directly to the extrusion..



The mount is pretty much universal and just attaches the BTT UPS 24V to extrusion with 2 drop in T slot nuts. For anybody that wants this mount it is shared freely right here: BTT UPS 24v Extrusion Mount by AutoWiz - Thingiverse
