Since this month I one now one small 3d printer. Its a "ender 2" with
an buildvolume of 165x165x200mm. For my purposes this is more than enought since I
always could print larger parts with the Toolbox e.V. Printers.
The printer was pritty easy to assemble and took just about 2 hours of carfully reading and
assembling the parts.
Out of the box the printer was printing prefect. But since i did know that the printer from
creality have disables safty features I installed the latest firmare from the [Marlin]{http://marlinfw.org/} github repository.
There I changed the config parameters to my need and enabled the folling options to lower the risc of fire caused by a pritner failure.
#define THERMAL_PROTECTION_HOTENDS // Enable thermal protection for all extruders
#define THERMAL_PROTECTION_BED // Enable thermal protection for the heated bed
With this option enabled I Printed a benchy which came out perfectly. A benchy is a small boot which you can see in the lower picture. It has some structural parts which are though to print.

I started to search for parts for a quadrocopter which could be used to race and do some
freestyle moves.
Here you can view the.. latest projects i've started.
Since for me also the assembly is new and I had the feeling that this quad will also be
likely to be damaged I wanted to build it with seperate components. Also its more fun that way.
Since I did not want to have a huge quad I wanted to hit the 250g Law limit for the assembly.
In such a case I would not even be forces to add a burn resistent name tag to the quad, which I
would anyway recomend if it could be lost.
After some search i found the [Diatone quad frame GT M3](https://www.banggood.com/Diatone-2018-GT-M3-130mm-Normal-X-FPV-Racing-Frame-Kit-RC-Drone-3mm-Arm-p-1257062.html) prity aplealing since they have a aluminum cage for the pcb stack and a 3mm carbon plate which is robust enought for a beginner.
The following motors where selected by taking the recomendations of the frame into account:
motorsize 1408
motorr 4000KV
The motor size of brushless motors for quadrocpters are regulary indicated by a 4-digit number
The first two digits represent the stator width or diameter while the second ones represent the hight.
The values types are in mm
In general the motor size have quite a infulence of the flight caracteristics.
A taller motor most likely result in more power at the upper Throttle/RPM and a wider motor
would result in a higher torque at low throttle.
Since i wanted to use motors with a actual datasheet or at least a messurement how much amps
would be drawn by them with a certain propellor i took the [T-Motor F20II F20 II 1408 3750KV](https://www.banggood.com/T-Motor-F20II-F20-II-1406-3750KV-Brushless-Motor-2-4S-For-130-140-150-FPV-Racing-Frame-p-1154351.html)

At this point the Motors and Frame where clear. The next step was to choose a propellor type.
For this I selected a tri bladed one with close to the 3040 size. The size for
