The Comp108 is an easy to print 108mm micro quadcopter frame designed to run 2.5" props and 2S batteries! Check out this video to see it in action with 7000kv and 7500kv 1104 size motors: https://youtu.be/IFpvkxkisDY
V1.1 Updates - minor changes to hole size to increase margin of error for printing.
This frame was designed with the following goals:
- Create a layout which can use a wide variety of components in an effort to increase participation in the MultiGP “Micro” racing class by allowing pilots to use parts they may have on hand.
- Develop a design which is functional, durable, and can be printed using a broad range of filaments and by individuals with minimal 3D printing capabilities.
- Explore the effects of bevels, chamfers, and infill patterns on the strength of a printed quadcopter frame.
The project resulted in the development of three different versions:
The Basher – This version of the design is based on the original concept drawing dimensions. It can be printed using PLA, and will still have plenty of strength. Of course, the tradeoff is that this is the heaviest version, but it will be tough!
The Racer – This version was created to see how thin and light we could make the arms and overall frame. After experimenting with materials we recommend that you print with more exotic filaments such as nylon, and even then be aware that you are trading durability for light weight and low drag.
The Cruiser – This version is a middle ground between the Basher and the Racer. While PLA will work for this version, you will gain durability if you print in ABS or PETG.
- The Comp108 frames can use flight controllers with either 30.5mm or 20mm hole spacing, 4-in-1 ESCs of both sizes or smaller individual ESCs, and 1103-1106 size motors (use 6mm bolts for motor mounting).
- We have designed a range of camera mounts, if you don't seem something that meets your needs feel free to be creative! Remember that the outside holes will line up with a full size flight controller mounting pattern, so you can use one of the many already available camera mounts, or use one of the flight controller stack plates as the base of your own design.
- The models should be printed logo side down for best results, and it is recommended that you take the time to orient your infill to align with the arms to increase overall strength (see picture for example).
- Experiment with materials, settings, and remember to have fun!
