customisable LED soldering jig

I liked the idea of [withanHdammit](https://www.thingiverse.com/withanHdammit/) of having a jig to solder LED stripes. Unfortunately, I needed a four pin version with a 90 degree bend. Since I expect a lot of people to need slightly different designs, I created a customisable model in OpenSCAD where you can change the number of pins as well as the width of the led stripe.

If you need the bend in the opposite direction, please mirror the STL in your slicer software.

Adjustable parameters:
* number: the number of wires needed in the jig
* width: the width of the LED strip; the width of the complete jig is 2mm wider;
* length: the total length of the jig
* wire width: the width of the channels for the wires
* length_straight (new): additional parameter that allows to have an additional straight section after the bend

The outlets for the wires in the jig will be evenly distributed over the length of the LED strip. Be carefull: if the number of wires time the wire-width is lar
