3D PRINTING


Have purchased an Ender-3 3D printer.
This is totally new to me, but this was very easy to get to work.
Drawing program is the free program DesignSpark Mechanical.
The program that generates the files for the 3D printer is Cura 3.6.0



Here I have made corners for a small box.

 


COIL-1

This is half the coil. Must be printed twice.


This is my first design.
RF coil form.



11uH, L=49mm, D=49mm, n=19



COIL-2

spole_2.stl
spole_2.rsdoc



My second design.
10.5uH, L=50mm, D=60mm, n=16


I am very pleased with this result after only one day.



COIL-3

I have designed a coil with two windings.
It is intended for a tube transmitter.
The outer coil is for the anode circuit.
The inner coil is for the antenna output.
Outer coil: 8.5uH, L=52mm, D=64mm, n=14
Inner coil: 1.6uH, L=17mm, D=50mm, n=5



Wind turbine made from beer can.



First test of the wind turbine.

Now it is finished and painted blue.




Double wind turbine.
Two sections with 90 degrees rotation.
A 4.5mm knitting needle is used as a shaft.
A drill must be used to make holes.
