During the process of designing stuff I find it useful to have a 3D model of the purchased components to hand so that I can ensure it is going to fit properly and allow me to design in features that will allow the item to be located and secured into place. Whenever I have searched around the web to see if someone else has already made a model of the item, I find that normally the answer is “No” and by that time I have burned up more time that I would have had I just made up the model of the component myself. So most purchased components that I have on my projects I have modeled in Blender with measurements taken off an example of the item. The models are not super detailed models that could be used in product commercials – they capture the main dimensions and appearance so that they can be used to help design devices that will make use of the component.
The more of these items I do, the more of a useful resource this library becomes for others who may be looking to fully model their design before they manufacture it.
The models are in a Blender format (using Blender 2.58) and an OBJ format.
Each model is in a zipped up package containing the Blender format model and the OBJ format. Some have a TXT file included that is just the information copied from the website it was purchased off. This will hopefully help you ensure the scale of the object is true if you are importing the OBJ format into another 3D package. Click on the image or the “Download” link for each component.
If you would prefer just to have all of the models then download this file (4.2Mb). All Component Models - Component_Model_Library-All.zip
Boscam 200mW 5.9GHz FPV Transmitter
This is a relatively low powered FPV video transmitter. It is a nice compact design and has a good range of frequencies that are compatible with most other FPV systems such as those sold by FoxTechFPV. The model can be downloaded from here: Boscam 200mW 5.9GHz FPV Transmitter
FatShark 100mW Video Transmitter
This low powered video transmitter was the one that shipped with my Video Goggles. Being so low powered it was quickly superceded by a more powerful one. By current standards it is a relatively large item. This now finds use on a small RC Monster Truck.

This is just a representation of a cloverleaf Antennae for illustration purposes. It is no particular brand, and the dimensions are not necessarily all that accurate. The model can be downloaded from here: Cloverleaf Antennae
Horyzon V3 Camera
This is a fairly sophisticated FPV camera that has a built in recorder. It outputs full HD video as well as a video signal that can be successfully transmitted through passive baluns over 100m of CAT5 cable. This is stocked by FoxtechFPV. The slightly cheaper equivalent is the Boscam Cobra HD FPV camera with Integrated Video Recorder 1080P from HobbyKing. The model can be downloaded from here: Horyzon V3 Camera
This is a lightweight full HD video camera for mounting on model aircraft, UAVS, etc. It is somewhat cheaper and sleeker than a GoPro.
The model can be downloaded from here: Wing Camera
An FPV Camera
This camera is based on the ANGTV CV-203AC Colour CCD Camera sold by www.goodluckbuy.com. Or at least I’m pretty sure I got it from them.
The model can be downloaded from here: FPV Camera 1
Another FPV Camera
This camera is based on the 1/3-inch SONY CCD video camera sold by Hobbyking.
The model can be downloaded from here: FPV Camera 2
2213N 800Kv Brushless motor
The motor used by the OpenROV is this one from HobbyKing. It is a fairly low power one but also low speed and so reasonable well suited to use in thrusters…..well so far.
The model can be downloaded from here: 2213N 800Kv Brushless motor
Car 45A ESC for Brushed DC Motors.
The Bilgepumps proposed as an alternative thruster motor to the 2213N 800Kv Brushless motor is a Brushed DC motor. While it only consumes about 5A, these 45A Car ESCs were the smallest ones I could find at the time from the HobbyKing website. They are a bit overkill. The model can be downloaded from here: Car 45A ESC for Brushed DC Motors
EZRUN 18A Car ESC for Brushless DC Motors
The HobbyWing EZRUN 18A Car ESC is the same ESC as used by the OpenROV project to drive the 2213N 800Kv Brushless motor. It is a nice compact piece of kit and has been used in the layout of the Open Source ROV I am working on.
The model of the EZRUN 18A ESC can be downloaded from here: EZRUN 18A Car ESC for Brushless DC Motors
A Quadcopter KK2 Controller
The very versatile KK2 Controller.
The model can be downloaded from here: Quadcopter KK2 Controller
A Plush 25A ESC for Aircraft and Quadcopters
This model is a bit simplistic but it gets the idea and the size of the unit across.
The model can be downloaded from here: Plush 25A ESC
A typical 9g Servo. You can download the model from here: 9g Servo
A Quadcopter Distribution Board
This component is a board for connecting the battery to four ESCs on a quadcopter. Each connection is a socket for a 3mm bullet connector.
The model can be downloaded from here: Quadcopter Distribution Board
This is a rough representation of the device. In truth they are wrapped in clear shrink wrap.
The model can be downloaded from here: Battery Alarm
White 12V LED Cornlight
HobbyKing stock a heap of these in different styles and colours. They are very bright and run nicely on a 12V or 3S LiPo supply. The model can be downloaded from here: Corn Light
The very versatile Arduino Nano. I have not detailed the pins projecting through the board but have instead included the socket the Arduino might be seated in. It would be the work of 2 minutes in Blender to remove the socket and extend the existing pin stubs through the board and down to the length required to represent the pins.
The model can be downloaded from here: Arduino Nano - Arduino_Nano.zip
A Couple of Hard Disk Drive Motors
Hard Disk drive motors come in a variety of shapes and sizes so there is a high chance that the ones you encounter are not like this. The model can be downloaded from here: HDD Motors
A Contact Button and Resistor
A typical contact button and a resistor. The Resistor model has been set up so that the colour bands can be changed in the sub-material sub-domains or whatever they are called.
The model can be downloaded from here: Contact Button and Resistor
2-Way and 3-Way Screw Terminals
There is nothing special about these. They are just you typical terminal headers suitable for use on a breadboard or perf’board.
A TO-126 transistor
This is a represention of the TO-126 package used for transistors like the BD681 Darlington Pair.
The model can be downloaded from here: TO-126 Transistor
A Mechanical Switch as Used on 3D Printers
This is quite a small one and the mounting holes vary from one type to another so don’t treat this model as the one and only type.
The model can be downloaded from here: Small Mechanical Switch
2100mAh 3S LiFe Battery
This one of the more stable and robust LiFe batteries. It has a lower voltage and energy density than the equivalent LiPo.
The model can be downloaded from here: 2100mAh 3S LiFe Battery
2200mAh 3S LiPo Battery
This is a typical 2200mAh LiPo battery of the Turnigy or Zippy brands as supplied by HobbyKing.
The model can be downloaded from here: 2200mAh 3S LiPo Battery
650mAh 3S LiPo Battery
This small battery is 11.1V and designed for control transmitters. This is used in some of my FPV projects to provide power to the video transmitters and camera rather than use the main battery.
The model can be downloaded from here: 650mAh 3S LiPo Battery - 650mAh3SLiPo.zip
2000mAh NiCd Battery
This is a rough model of the 7.2V NiCd battery packs for Tamiya radio control cars. The model was originally produced to illustrate some of the PS2 and Arduino projects. The overall size is correct, but I wouldn’t rely on the finer details being accurate.
The model can be downloaded from here: 2000mAh NiCd battery - 2000mAhNiCd.zip
