B18650 battery holder for welding

This is a couple of 18650 battery holders, to hold the batteries in place while welding the batteries together. The first STL is for 1 row of 7 batteries and the second is for 3 rows of 7 batteries - this because it was for welding together batteries for Ambrogio (Stiga, Wiper, Alpina) robotic lawnmowers. Using the supplied "holder.scad" (note: It has to be renamed "holder.jscad" - it is not an OpenSCAD file, but Makeronline will not let me upload the jscad file) you can modify the holder to any number of rows and number of batteries per row - just change the defines "NUMBER" and "ROWS" at the top of the file and use "OpenJSCAD v1.x" to render it and save it as a STL. You can find a OpenJSCAD v1.x e.g. at https://sam-ross.github.io/OpenJSCAD-Threejs/static/htmlPages/OpenJSCAD.html).
