Caliper Battery Separator (Improved)

thingiverse

I tried out Arbitur's remix of the caliper battery separator and it snapped off my negative battery terminal spring. I had to disassemble my caliper and re-solder the terminal back on. I was inspired by his remix and wanted to improve upon it, since I use my calipers frequently and want to save the battery when not in use. I also appreciate Derailed's original design, which I've added as a source if you prefer to use his design. This modification may or may not work for you due to the numerous caliper versions available. Be extremely cautious not to snap off the negative terminal like I did and have to disassemble the caliper to re-solder it back on. Here are the improvements I made: - I rounded out the angle cut, as my caliper has the negative battery terminal soldered at an angle. This prevented the negative terminal from being stressed and breaking off. - I reduced the thickness and uniformized it: this decreased the upward pressure on the battery cover and potential breakage. - I shortened the overall length so that when I move the separator a few millimeters up, the caliper stays in place and doesn't have the separator sticking out while measuring things. - I added an optional EDGE to the button handle, allowing you to push up the separator instead of pulling on the handle. The other option is FLUSH. I use the EDGE version to turn my calipers on/off now. - I included a shorter width version for my other NEIKO caliper, both FLUSH and EDGE versions depending on your preference.
