Printed up perfectly and nice snug fit, but I've struggled to clip the cover into place - it doesn't seem to click in (yes I have the indents facing into the box). Does it need to be pressed in really hard?
Case for ESP32-C3 SuperMini and LD2410C
A simple case for using an LD2410C radar sensors with an ESP32-C3 SuperMini. Includes multiple backs for mounting.

It should be relatively snug, but you shouldn't have to hit it with a hammer. It's hard to account for small variations in dimensional accuracy for every printer. I would try scaling the backplate down to something like 99% if you can't get it to go.
@FriedCheese20_596762 I realised I had the lid upside down - with the indents facing down. That seemed correct, but when I flipped it over it snapped right in. Possibly I missed that in the instructions, but if not it may be worth noting it.
Thanks again!
How do you snip off the “out” pin on the LD2410C?
@musterpck_3029532 I have a big set of flush cutters but it can also be pulled out with pliers while remelting the solder with an iron.
Does snipping the OUT pin from the sensor not limit the capabilities in any way?
@Chaoscontrol_3005345 yes and no. My understanding is that the out pin can be used to let the sensor determine and signal motion based on the light sensor, but the general consensus is that the built in light sensor is garbage.
Works great, I especially like that there are instructions for the full project and not just a 3d print.
If I can suggest an improvement, it is to add another back that will fit the case in to a corner. I think in many situations presence detectors are placed in corners for maximum coverage of a room. In my case the ball attachment did the job well, but I think if it was placed flush in the corner it would have been better.
Thanks for the make and glad it worked out. As far as the back, I may be able to spin something up. There is one for the corner, but I presume you mean one for the corner that will let you mount it vertically.
This was a pretty quick and easy print. Getting the device inside and aligned is a bit challenging. A deburring tool goes a long way to make little adjustments. Other than that, works like a charm!
Great model! I see with your S2 version there is a hole for the light sensor. Can you make a version of the C3 that includes that light sensor hole?
Thanks, fit perfectly..
Wanna ask, is this C3 super mini get hot when operate?
Mine is above 60 Celcius with room temp about 32 Celcius, is it normal?
@bjk8kds_2502967 yeah...mine cook too. I found that they do run cooler when mounted on the wall over sitting on the desk. The LD2410 contributes to heat buildup of the ESP board. All within specs though.

I really like the physical design and small and simple packaging but sady I can not get the sensors to work with the provided esphome config file.
They only report the ld2410 firmware version and mac to my HASS when connected but all the state variables remain unknown. Does anyone here have an idea what could cause such weird behaviour?
It seems like the ld2410 sends its ID on boot but then times out before any values can be read
@DavidM_1414778 make a post and tag me (same username) in the HA forums and we can try to get you sorted.
@FriedCheese20_596762 turns out that particular ld2410 I was using seems broken.
I can't event connect to it with the HKLink App for more than a few seconds. I soldered another one and it works now 🎉
Thanks again for your really nice design, such satisfying snap fits and your willingness to help
great job! thanks!
printing material and color has any incidence on the sensor?
@AlejandroTram_720674 Not that I've noticed.
@FriedCheese20_596762 Thanks.. will try with some PLA CF i have loaded
Amazing! thank you for this!
