Channel
thingiverse
This customizable channel is based on the FTC part, and includes a .txt file that can be downloaded for modification. To tailor the channel, simply copy-paste its contents into Thingiverse and alter the two values within the parenthesis of "channel1(5,2):". The first value determines the number of holes in the channel, while the second value controls the distance between the top circle edge and the channel's perimeter. If a non-alternating hole design is preferred, replace "channel1" with "channel." Suggestions are welcome for further customization options.
With this file you will be able to print Channel with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Channel.
