Veml 7700 outdoor case

Veml 7700 outdoor case

Cover for veml7700 by adafruit, for outdoor weather station.
The box is divided into two parts. The upper part is made of transparent PET-G filament with 100% filling. The hexagon on top should help guide the light to one point, the sensor.
The lower part is printed from white PET-G, with 100% filling. On the bottom side there is a hole for a 19mm diameter cable gland. There is a 1.6 mm groove on the top for sealing. I made the seal by inserting 1.75mm TPE 32 filament into the groove. This should ensure IP44, which is sufficient for outdoor use (I do not guarantee). I only tried it in the sink and running water.

Screws

The model contains 7x M3 threaded inserts, which must be pressed in with a soldering iron.
All screws are M3 with a length of 10 mm, with an Allen cylindrical head.
- 4x for attaching the top part
- 3x for attachment to the holder

About printing

The model is printed from PET-G for better thermal stability and UV resistance. The hexagon top cover is printed with 100% fill. Although the light is dimmed, it does not refract outside the hexagon.
The top cover is printed on the supports, see example below.
I tried the bottom cover with 15% and 100% filling. Functionality is not limited in any way.

About project

The weather station project, I will publish gradually. This project will run on ESP-8266 / ESP-32. I will gradually publish the code on my github.

Development

☐ Create a cover without a hexagon
☐ Create the lower part without the grommet hole
☐ Create a holder for the box
☐ Create a box without holes for the holder
