Cut the heatsink to 345 mm length or buy it with this length.

I you want to use your LED stripe or LED module as long as possible, use a heavy heatsink.

!!!! The normal "little" lightweight heatsinks definitely do not dissipate enough heat from your LED. !!!!

1. Clean the heatsink with alcohol or isopropanol.
2. Solder before stick it, cause the heatsink suck all your power from soldering iron

cut your acryl like in the drawing.

Print both Housing parts. The second is for 8 mm Power Jack (Very common in Germany).

If needed print the angle(Winkel) parts. The angle is about 12 degree.
