This LED Strip Mount is based on two parts which can be connected to reach a total length of 400mm. I used Prusament PETG and wouldn't recommend PLA (believe me I tried and the 24V Strips I used get a little too warm for a longterm use).
After I sticked both parts together, I used double sided tape on the back and sticked them to the top. Afterwards I used 3mm screws to make sure nothing will come apart.
I used the standard Prusament PETG settings in PrusaSlicer (no support and 15% Infill)
