I love the Zooz ZEN37 Wall Remote scene controllers for controlling WLED lights... but I didn't love that they felt a little small and a little fragile for my young kids to use. So, I designed this case.
The case gives the controller a bit more heft for small hands, and lets me use a unique pop of color to easily identify whose controller is whose.
The case is versatile: You can carry it around, hang it on a hook (we love 3M command hooks), or embed 5mm round magnets during printing to be compatible with the original magnetic wall plates (which we also mount with large command strips, e.g. to the side of a kid's dresser!). You can still charge the remote with the case attached.
Note: Embedded magnets are fully enclosed by the end of the print so that they require destructive disassembly of the case to access. Removing the remote does not give access to the magnets.
The ZEN37 snaps into the case and is firmly retained by a narrow overhanging lip along the sides, but can still be removed (by a dexterous, tool-using adult) by inserting a narrow object between the ZEN37 and the case in the charging slot area. (Caution: Do not use the USB-C port to pry with or it may break: the case opening allows access behind the remote. See photo.)
Magnets
I used these bulk "5x2mm" magnets from Amazon, which had real-world measured dimensions of
5 x 1.75mm.NOTE: The case is sized for my real-world dimensions, with an internal cavity of 1.9mm height. It would not fit a magnet that's genuinely 2mm tall!
In PrusaSlicer, I added a pause at 3.00mm (the start of the bridging layer that would enclose the magnets) to allow magnet insertion.
Magnets MUST be correctly oriented!
The magnets in the case must attract the ZEN37, not repel it!
Use the ZEN37 itself to check the orientation of your magnets.
One way to do this is take a tall stack of your magnets, stick the whole stack to the back of the ZEN37, and then (while everything is stuck together, ensuring your orientation is correct) push one magnet into each hole and slide the stack sideways to leave it behind.
Printing
I've included a .3mffile of my printed settings, including the magnet stop and necessary supports.
I used PLA, but other materials should work as well.
0.2mm layers, 3 perimeters, 15% infill
Optional: Pause at 3.00mm (layer 22 of 0.2mm layers) for magnet insertion
Supports on the hook area only - not necessary for the charging slot
