18650 Battery Spacers -- Interlocking

thingiverse

Single cell and 3 cell spacers for organizing battery packs. They are a little difficult to print due to the little dovetails. Print the first few layers slow and you should be good though. No support needed. I haven't tried printing them on rafts because I hate rafts...that said, they may print better on rafts <strong>Edit: </strong> I uploaded new versions of both as they were a bit too difficult to snap together. Also shortened the male dovetail to 8.25mm to make them line up better. 4/25/2018 - Added a second single cell version with flare at the bottom of the female dovetail to assist in mating the pieces together. I'm pretty happy with the fit. 5/11/2018 - Added a little shorter version to improve print time. This one's main body is 7mm and the little tabs are an additional 1mm so total height is 8mm. <strong>Note:</strong> The single cell spacers do NOT mate with the 3 cell spacers. Also note that there are several iterations in the photo. The latest 3 cell are the 2 top ones on the pack. <strong>Customize:</strong> Since all cells are not exactly the same size, I'll provide the link to the OnShape files. Just edit sketch1 in each and modify the hole size. They are linked so just edit the dimension shown. 18.75mm is default. http://bit.ly/2Ht7DOg -- 3 cell http://bit.ly/2HnYEh4 -- single cell
