Description
This is a magnetic mount for SMLight SLZB Zigbee Ethernet / USB LAN adapters.
It builds on my original screw-mounted design, but replaces screws with press-fit magnets. If you prefer to install with screws, check out the original version.
This model is designed to use magnets:
once installed, the magnets are firmly retained and won’t fall out during normal use
No glue is required:
Flexible grip fins hold the magnets securely
Lead-in chamfers help magnets press in easily. Insert from the inside/front of the model.
Compliance so tolerances across printers/materials aren’t an issue
Through-hole design so magnets can be removed easily for reuse
I parameterized the model to support different magnet sizes. The diameter can change, but the maximum thickness supported is 3mm.
I recommend using 6mm x 2mm or 6mm x 3mm Neodymium magnets (N42 or N52). Some users have reported that using only 2 magnets wasn't strong enough (likely not using Neodymium magnets), so I have since added a model that can hold 5 magnets.
I also published models for 8mm magnets. But those magnets are a bit large for the x5 (5 magnet model) .. so I made a 4 magnet model.
You can customize the magnet diameter with the included Fusion files. You can also do this online on MakerWorld via the 'Customize' button: https://makerworld.com/en/models/2560278-smlight-slzb-06-slzb-mr-magnetic-mount

You can Customize this on MakerWorld here for different size magnets. They should not be thicker than 3mm though.

Same core design as the original, using compliant features:
Small retaining nubs align with vent holes and hold the device securely without blocking airflow
Flex slots allow easy install/removal
Two large keys + outer rim prevent side-to-side movement
Device removes by pulling straight out
The fit is tuned to balance snugness with ease of use.
Insert the magnets from the inside/front and push flush to the back of the mount
