After designing V1 of this fine clip for fixing LED strips using screws,

and developing V2 to be able to use them with diffusers,

I have prepared these profiles with fixation by inserting magnets.

This idea came because I am aware that there are LED strips with built-in magnets for installation in desktop computer cases. Nobody would want to drill holes in something so valuable to install some LED strips. I also relied on the small profiles that run on a rechargeable battery and are usually used in closets.

The profiles are distributed by LED strip size in this way:
Plate 1: 4mm with 4mm magnets.
Plate 2: 5mm with 4mm magnets.
Plate 3: 8mm with 6mm magnets.
Plate 4: 10mm with 8mm magnets.
Plate 5: 12mm with 10mm magnets.

The maximum height of the magnets is 3mm. It is not necessary to install all the magnets in all the holes. I have inserted so many holes for magnets that the strip will not fall off easily even when installed upside down, believe me xD

I have added 3 different lengths of these profiles: 19mm, 50mm and 200mm. These profiles are assembled together in a modular way and have sufficient lower layers to resist the force of the magnets and maintain the magnetic force.

The process to follow would be the following:
0: Download the 19mm model to check if your LED strip and magnets are inserted correctly.
1. Check the installation length and download the necessary parts.
2. Insert several magnets and check that the profile adheres correctly.
3. Install the led strip and double check if the magnets can support the current weight. Otherwise, remove the LED strip and add more magnets.
4. If you are going to use a diffuser, download the correct width and distances and insert them onto the profile. Remember that the diffuser will expand the width of the profile by about 2 millimeters.

So far I have not had a problem with heat since I use low density LED strips, but if you decide to use these diffusers with high density LED strips, take into account the melting temperature of the material you will print with so that there is no warping over time.

NOTE: Be aware of the temperature generated by the LED strip that can build up inside the tube and warp it. There are LED strips with high density and voltage that could exceed the melting point of the material.

In this case, I recommend printing in PETG.

Believe me: I have seen LED strips that reach 60 degrees in temperature and with 2 LED strips inserted in PLA and at maximum

performance it is very likely that this will end very badly.
