Description

Hang devices as intended. Customize your keyhole mount adaptor for OpenGrid or Multiboard.

I designed this model to solve a common frustration with mounting hardware like power bars, switches, and routers to modular wall systems. Most existing solutions use "captive shells" or bulky enclosures that trap heat and force devices into awkward positions. I wanted a way to hang devices exactly as the manufacturer intended while utilizing the versatility of OpenGrid and Multiboard.

By using a thin-plate design, this adapter ensures your electronics have optimal air circulation for cooling, preventing the thermal buildup often seen in enclosed mounting options.

⚠️ Important: This model must be opened in MakerWorld to be customized. Customization is not compatible with Handy App or Bambu Studio at this time. https://makerworld.com/en/models/2484153-opengrid-multiboard-keyhole-adaptor-plate#profileId-2728747

Features

Dual-System Compatibility: Native push-fit support for OpenGrid and Multiboard organizational systems.
Fully Parametric Design: Utilizes OpenSCAD to allow users to generate custom plates by adjusting hole sizes and locations to fit any specific device.
Hardware-Optimized Hanging: Enables mounting of power bars, routers, and switches exactly as the manufacturer intended using their original keyhole slots.
Advanced Thermal Management: The thin-plate geometry promotes superior air circulation and cooling compared to restrictive, heat-trapping captive-shelled designs.
Universal Hardware Support: Specifically designed to incorporate self-tapping screws for a secure, custom-fit mounting interface.

Specifications

Compatible systems: OpenGrid, OpenGrid Lite, MultiBoard
Customizable plate size
Customizable screw location
Screw Compatibility: M3 (customizable)
Plate Thickness: 2mm (customizable)

@Erickm111

ok, i feel foolish, but i cannot for the life of me figure out how the screw hole position works on the generator. my power strip has 4 holes on the bottom, they are 113mm apart long way/end to end so to speak, and 25mm apart width way/side to side.

The designer has replied

@PixelFanLabs

Are you planning on open grid or multi board?

@PixelFanLabs

Open grid is 28mm grid size. Keeping the plate size in this standard would looks best. Plate_Width = 140mm. Plate_Depth = 56. Position = [13.5,15.5],[126.5,15.5],[13.5,40.5],[126.5,40.5]

@PixelFanLabs

Multi Board is 25mm grid size. Keeping the plate size in this standard would looks best. Plate_Width = 125mm. Plate_Depth = 50. Position = [6,12.5],[119,12.5],[6,37.5],[119,37.5]

@fukai_mori

Love this and thank you for sharing. qq is there a way to remove the countersunk holes? I'm not seeing the option in customization but would be helpful to remove them.

The designer has replied

@PixelFanLabs

Hi, by countersunk, do you mean you don't want the holes to go through to the snaps? There is an option called Extend_Hole you can turn off for this. You can also manual set the hole depth of you want it to extend partially.

@fukai_mori

Replying to @PixelFanLabs :

Hi thanks for quick reply back. By countersunk I mean the opening hole made on the face plate has a bigger diameter than the hole set in the customization. In my case a 5.4mm screw hole diameter has an opening of 6.4mm diameter. Is there a way to remove that opening in the customization to have the entire hole the same diameter? Apologies in advance if there is a way and i may have missed it.

(Edited)

@PixelFanLabs

Sorry for the delay. I have added an option under the "Screw Settings" section called "Counter_Sunk_Hole". You can now set this to false to remove the countersink

@cmcfearin

Could you explain how best to measure the key hole positions to input the coordinates? Thanks!

@timjjefferson

I made the assumption that the coordinates are mm. My powerstrip has only 2 holes, measured to be 159mm aparts. The coordinates I therefore used were: [[20, 17.75], [179, 17.75]] with plate 'height' adjusted to 40mm and 'width' to 200mm. (I might need to make further adjustments on the plate for stability, but the x values are spot on))
