Grove moisture sensor body

myminifactory

So you just bought a grove moisture sensor from Seeed and you wanna use it by putting it directly in the ground. I'm going to do this, but I don't want any damage on the electric components. So I drew a body in Solidworks and 3D print it with my Prusa I3 MK2S MMU. And to protect everything I fill it up with epoxy resin. In the box: When you download the file you can make changes and redesign it for personal use, I really don't care! But you are not allowed to share any of my products before or after a redesign or modification. Nor can you take credits for any modification you have done without my consult or approval. There is also a STEP file included for the people who wanna make changes to the body. Draw product: First, I made a nominal drawing of the sensor and added a 0.25mm offset. When there are small differences with the sensor it would always fit in the body because you have a tolerance of 0.5mm in total. Printing: I used a Premium PLA from formfutura.com with a 102.50% scale. If I would print it again, I would lower the Scale to 101.50% or try it without scale. It would fit theoretically. But after the print? Well, if you are done with printing, you can fit the sensor in the body. The two plastics sticking out are for you to melt so the sensor doesn't get loose on the body. You get a small metal pin and heat it. The temperature doesn't need to be high because PLA gets soft around 60°C. I use blue tape to tape down the body (except the wires) and then I used an epoxy resin, which also I use with my polyester glass fiber, and fill up the whole sensor and body. After 20/30 min you can take off the tape (this depends on the epoxy resin to harden) and you have a sensor that is sealed.
