Sometimes it's necessary to solder wires directly to LED stripes instead of using connector plugs. I'm using this tools especially to make connections if I use the LED stripes in wet or damp environments to prevent the contacts from oxidation. 1. I solder the wires to the LED stripe, 2. seal it with rubber seal like Plasti Dip, 3. cover it with shrink tube.

The tools are in four different sizes for 8, 10, 12 or 14 mm LED Stripes to ensure that the wires and the LED stripes are aligned and fixed to each other so that soldering of all connections can be easily done in one workstep.

The STL file name contains the width and the part numbers for the different tool sizes. For example LED-Stripe-10-P2. STL means size 10mm Part 2

Filament: PETG
Layer hight: 0,2mm, 20% infill, no supports

As an alternative to the originally tested springs I made a version of the tool that can be used with ballpoint pen springs of various sizes. Because there are lots of different ballpoint pen springs (different diameters, length and force) you have to try if the tool works correct. In most cases you have to shorten the ballpoint pen springs.

All STL files for the ballpoint pen spring Versions  are starting with a ‘P’
