I have printed the bottom part, and I am printing the middle. I also completed v1 of the design, so the top part now has room for temp and sun sensor + acrylic glass.

I will also design some gaskets to be printed i flexible material.

Ill post some pictures when im back home.

So in V1 there is no counter sunk holes for screws on the bottom part.
The mounting position for the sensors between the bottom and middle part is raised to make more room and less likely for rain to blow in when it's windy.
The top part has doubble walls for the screws and with narrower holes, so wood screws can get a better hold.
I also changed to 4x50mm screws.

On the top part I added a indent to hold a 95x95x2mm acrylic plate with room for a gasket around the edge and around the holes for 4x15mm screws.
Then a second 62x62x4mm indent to hold the solar cells and IR sensor, with some more indents to route the wires. Ending with a hole down to the arduino compartement.

I printed the bottom part and am printing the middle part. They look to be printing well. The top part will be a longer print thoug.

Great work! This is going to make a great HOWTO for an INDI website article! We didn't have one in a while, so hopefully once all of this is done, you can summarize all the steps for those who want to follow in your footsteps!

Yes. I can absolutely do a writeup when its done.

I wil have to wait for the sensors to arrive first. (10 - 35 days from China). Just in case I have to change anything to make the sensors work.
I wil post the printed body in about 4 hours. I have printed the bottom and middle, and the top is 50% done.
I wisited my 3d printing store and got a 10meter sample of TPU that I will try to print the newly designed gaskets in.
Hopefully it will work, but TPU is listed as 'Expert' in the dificulty level, so no guaranties :)

Heres the drawings of the gaskets for now.
Not a hwole lot to look at, but I made the area a little smaller than the slots they go into, and made them one layerline taller so they will get squshed and water proof when everything is screwed together (hopefully).

Print done! From Idea to working part in two evenings :)

I took some assembly pictures for pending howto. Just have to get the electronics.
The small gasket was also one mm to thick, so will fix that.








I got some 2mm acrylic glass, so I'll try cutting that tomorrow.

That's 3D printed? wow, it looks so neat.

Yup :)

3d printin can be wery neat if the limitations have been considured when designing the part.

This print is actually printed at 0,3mm layer height, witch is about the lowest 'resolution' recomended for a printer with a 0,4mm nozzle.

It could be even smoother at 0,1 mm layers, but would take much longer to print.

So now the glass is cut and drilled, and a new 'frame' to screw on the glass with even pressure.

I printed the top gasket in PLA (hard material) to use as a cutting / drilling template, so getting the holes right was easy.
I have also sourced a solar cell from a led light that I was not using. I'll have to check it at midday when it's not clouded to see that it does not generate to hig current. It registered 1.5v under a bright light, so I'm thinking it will be ok.

Pictures of the complete box. Whit the new 'frame' on top it's now 10^3cm

That really look cool. When are you expecting to finish it?

Thanks :)

It all depends on shipping times.

I ordered all the sensors from ebay, and they all had 10 - 35 days shipping.
I have been supprized sometimes when ordering things from China and got the items closer to the 10th than the 30th day.

I will order the arduino and the wifi module, so I can set everything up and be ready to install sensors.

Btw. Does the indi driver for indoino meteostation connect to the arduino ower the network, or does it need to be connected in some other way?
I also tested the solar cell in cloud free daylight ~17:00 pointed at the sun. It was producing around 2.5v, so I think I can connect it directly to the arduino without any resistor to split the voltage.

The arduino was connected to the Pi USB port.

A very professional job!
If you are happy to share your STL files for the £D printer design, i'm very temped to have a go myself. :)
