Wall / Ceiling / Under‑Shelf Holder for AC LED Tube Retrofits

I needed a way to mount some AC “neon style” LED retrofit/replacement tubes to walls, ceilings and under shelves, so I designed this set of end‑holders.

• Holds standard AC LED tube retrofits by the ends
• Works on walls, ceilings, under‑shelf, or metal structures (with the magnetic version)
• Provides space for a simple screw terminal block (“domino” connector) at the powered end
• Mounting holes are sized for screws up to Ø4 mm (wall mount version)

Use two holders per tube (one at each end).

Versions

• Neon_Screw_Wall_D4mm.stl – The main one ! Screw‑on holder for wall / ceiling / under‑shelf mounting
• Neon_Magnet_D25mm.stl – Magnetic holder for Ø25 mm magnet
• Neon_Magnet_D25mm_AC_side.stl – Same, with cavity for AC connector side
• Neon_Magnet_D30mm.stl – Magnetic holder for Ø30 mm magnet
• Neon_Magnet_D30mm_AC_side.stl – Same, with cavity for AC connector side
• Neon_Magnet_rect_10x20mm_AC_side.stl – Magnetic holder for 10×20 mm rectangular magnet, AC side

The "magnetic" versions use two magnets per end, tilted at 45° so you can clamp the tube neatly in corners or on steel beams (IPN, etc.). 

Assembly:

1. Print two holders per tube. Slide on the neon tube.
2. At the AC side, route the wires through the holder and connect them with a standard 2‑pole screw terminal block (“domino”) inside the cavity.
3. Screw the holder in place (or insert magnets in the magnetic versions).

I don't necessarily expect anyone to download this model, but I am currently cataloging every project I’ve done around the house with 3D printing... because OCD.
Hope it helps someone anyway!
