Magnetic (or/and velcro) led light tube holder

A mounting bracket for an LED tube light up to 30 mm in diameter (the ones in my photos are 29 mm, and the bracket was designed for that size). The bracket includes a cable pass-through hole and can be attached in two different ways:

- Magnetically – this requires four round magnets 10 mm × 3 mm for each bracket. (You need two brackets to mount a single LED tube, one for each end) - With a hook-and-loop (Velcro) strap - max 2cm wide – for non-magnetic surfaces. (I used inexpensive straps from Aliexpress) I also glued a small piece of rubber sheet to my brackets to reduce slipping when the tube is mounted vertically. However, with the magnets holding so firmly, this wasn’t really necessary—even the power strip hanging from the lamp stayed in place securely.
