Repair of a thermometer with a 3D printer
This thermometer hung outside the window for several years, due to temperature changes the plastic mount literally crumbled into small pieces in hands. Repairing a thermometer with a 3D printer cost ten minutes of modeling and a few grams of plastic.
He printed new parts on a 3D printer made of ABS plastic, as time will show how it behaves in the cold. Until I hung the thermometer back, I can’t open the window, there is still a New Year's garland on the address LEDs .

I also replaced the graduated scale with humidity, drew and printed a new one on the printer. The picture for printing is in the archive with the project files.
There was a mountain of packages that occupied a whole drawer in the kitchen. And now there is a small box with packages. The whole secret is to roll packages with a simple device.

Bowden extruder for a 3D printer with minimal gaps and no extra parts. An eccentric is provided for compressing the spring and releasing the filament rod.
For my daughter, I printed a little Wally made of plastic, she is crazy about this toy, especially since dad made a toy.
The 3D model of the fan is very simple, easily wound on a collet clamp. I put it on my CNC machine. The first launch proved to be very good, all the chips are scattered to the sides, clean under the cutter.
