Round wall shelf for air purifiers, lights, and pots

“AirLift 230” – Round Wall Shelf (Ø 230 mm) in Two Variants

Designed for air purifiers. Made for much more. 😊

This round wall shelf (Ø 230 mm) elegantly brings heavy candidates like air purifiers (for me Levoit Core 200S and Core 300S) from the floor/table to the wall – for me directly above the 3D printers, so that the air gets extra support during printing (yes, even if some printers already have filters… two is better than one 😁)

“Fits perfectly for…”

• Air purifier up, cable down
• Lights, speakers & home accessories
• Plants, busts & decoration with a stage
   

The assembly consists of 2 parts each:

• Wall mount (2 variants):
  
  without cable management (universal for everything)
  with cable management channel (perfect for air purifiers & cabled devices with Euro cable dimensions)
   
• Shelf plate (Ø 230 mm) with a slightly recessed, rounded inner shape so that devices stand neatly and centrally

The shelf plate is inserted centrally via a guide, sits approximately 2 mm “flush” in the holder (looks like one piece) and is additionally fixed from behind with a countersunk screw (M4×20mm – M4×30mm). The screw hole is additionally deepened so that shorter screws can be used.

In the variant with cable channel, the cable runs guided at the back and comes out centrally at the bottom. With a small cable loop (at the top), the air purifier can even be tilted sideways for filter replacement without having to unscrew the holder - I tested it. For the three front-facing wall screws, there are 3 cover caps to keep the look clean.

Tested: Levoit Core 300S and Core 200S fit – and anything with a suitable footprint (e.g. larger plant pots, decoration, lights, etc.)

Note: Load capacity depends heavily on the wall, dowels, screws, and material. Please dimension appropriately – we want “AirLift”, not “AirDrop”. 😅

Features

• Ø 230 mm shelf plate, rounded/recessed inside
• Slide-In guide + rear fixing screw (countersunk)
• 2 wall mount variants: with / without cable management
• Cable outlet centrally at the bottom (e.g. for attaching a cable channel)
• 3 cover caps for the wall screws (front of the wall mount)
• Stable honeycomb support (light + stiff)

Assembly / Hardware

Assembly:

1. Insert shelf plate into the wall mount
2. Fix from behind with countersunk screw
3. Screw mount to the wall (3 screws)
4. Attach cover caps
5. For cable channel variant: Insert cable neatly before wall mounting and lead out at the bottom
   (Tip: leave a small loop at the top exit - this simplifies filter replacement later, two helping hands would be advisable 😁)
6. Bonus profile: Drilling template with spirit level rest – so that "eyeballing it" doesn't win again. 😄
    

Hardware:

• 3× Universal screws (pan head) 5×40 mm (or longer, depending on wall/dowel), countersunk head should also fit
• 1× Countersunk head M4 × 20mm to M4 × 30mm (fixing shelf plate in holder (backside))
• suitable dowels (wall dependent)

Update/Changelog

• 05.03.2026: Drilling template profile added (incl. 90° spirit level rest for straight mounting)
• 21.02.2026: Release of the round wall shelf 230mm with two different wall mounts

Print Settings

Recommended material: PETG, alternatively ASA/ABS.
PLA often works too, but for continuous load + heat, PETG/ASA is preferred (creep says hello).
