Talk about making a small drone “Tiny Whoop” frame on a 3D printer (Part 2)
『Synopsis to the last time. | A story about making a frame of a small drone “Tiny Whoop” with a 3D printer』
I tried to output Tiny whoop’s frame with a 3D printer using data downloaded from Thingiverse.
However, since it was not possible to find a form of data convenient to mount the battery I have, I decided to design a frame that is convenient for loading the battery.
『Tiny Whoop and there are actually a lot to say in a bite.』
Examining and looking at, Tiny whoop’s battery uses LiPo battery (lithium polymer rechargeable battery), but its shape does not necessarily remain constant.
Furthermore, I remembered that in addition to a vertically elongated lipo battery, there are several Lithium Batteries that I could not use because I had bought it before as I tried to use it in the work but the capacity was insufficient ).
For Tiny whoop, there seems to be little capacity, but if you use it for practice it will be enough.
Therefore, I thought that it would be possible to install any of these types of Lithium Batteries or even other types of Lipo Batteries.
In addition, the following requirement is set with reference to the data of the frame published in Thingiverse.
Be able to mount a LiPo battery that is supposed to be used.
Easy attachment and detachment of the motor.
It is possible to output without problem with a 3D printer which is not so high performance.
It is easy to change the design when the dimensions of various parts change.
1: It is possible to mount a LiPo battery that is supposed to be used.
As for 1, we will respond by attaching a different mounter to the frame depending on the shape of the battery.
2: Easy attachment and detachment of the motor.
2, by inserting a slit in the cylinder part where the motor is mounted, it absorbs the error in the output dimension of the 3D printer and works to strengthen the force to hold the motor by the reaction force of the material.
3: It is possible to output without problem with a 3D printer which is not so high performance.
As for 3, since the 3D printer at hand is not so high performance, the resolution is not very good. Also, since filaments are not so expensive, precise output can not be expected.
Even in such a situation, I will consider it so that the frame can output properly.
4: It is easy to change the design when the dimensions of various parts change.
As for 4, as for the battery, main board and motor are not necessarily unified shape and dimensions, so we consider that you can easily change the dimensions so that we can respond to such things as much as possible.
Next time, based on this requirement, we will design 3D data using CAD software.
