Broadlink RM4 Mini Wall Mount – Tape mount

Broadlink RM4 Mini Wall Mount – Tesa Powerstrip Edition

Based on Broadlink RM4 Mini Wall Mount Modern Design by acosta290.

I wanted a damage-free wall mount — no screws, no holes, no permanent marks. I also wanted to keep using the original Broadlink twist-lock adapter. So I redesigned acosta290's mount to suit these needs.

Features

• Adhesive mounting - single Tesa Powerstrip (or similar). The 65 mm tall back plate provides full contact area for the strip's rated hold. Pull tab points down.
• Original twist-lock adapter - M3 screw bosses with hex nut traps let you bolt in the stock Broadlink adapter. Drop in the RM4 Mini and twist to lock. Note: the adapter doesn't center the device perfectly, but it does let you align the LED with the front slot.
• Cable channel - USB port faces the wall. A 32 mm deep channel routes the flat USB cable cleanly out the bottom.
• LED slot - narrow notch at the top front edge for status LED visibility.
• Ribbed texture - vertical ribs cover the entire surface from front to back.
• Parametric source - .scad file included. Tweak cavity size, cable gap, plate height, etc.

Printing

• Material: PLA (printed with Bambu Lab Matte PLA, ~40 g)
• Profile: 0.16 mm High Quality @BBL A1
• Supports: Tree (auto), threshold angle 25°
• Orientation: Bottom down
• Print time: ~3 hours

Assembly

1. Press M3 hex nuts into the traps inside the cup. A tiny drop of super glue secures them permanently (recommended).
2. Screw the Broadlink adapter to the base with two M3×8 screws.
3. Route the USB cable through the back channel and out the bottom.
4. Attach a Tesa Powerstrip to the back plate. Choose the right strip for your wall surface— Tesa makes variants for painted walls, wallpaper, tiles, brick, etc.
5. Press firmly against the wall for 30 seconds, wait 1 hour before mounting the device.
6. Drop in the RM4 Mini and twist to lock.

Notes

• Cavity is intentionally loose — the twist-lock adapter handles retention.
• Without the adapter, reduce cavity_r in the .scad file for a friction fit.
• Device + mount weigh well under the strip's 1 kg rating.
