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.
I decided to try how my homemade 3D printer will cope with small models, for this I chose mini-toys and printed them.
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.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
I present to your attention a homemade 3d printer. Assembled from plywood, aluminum, plastic and Arduino. This printer is unique in that its kinematics is peeped from Ultimaker, but done with quality modifications.
For my daughter, I printed a little Wally made of plastic, she is crazy about this toy, especially since dad made a toy.
