This is an incomplete work in progress that I figured I would share and see what people thought. It consists of 4 files that can be combined in 123d or similar software to make a complete tunnel. The measurements should enable it to work with a certain name brand ferret tunnel.
Tunnel format is as follows......
1st. Tube Mouth
2nd Tunnel Part (add multiples to achieve length)
3rd Tunnel Blank
4th Tunnel Finial
Also needed is a grommet to keep the tunnels together (as with the name brand tunnels). Again this is a project for a later date.
Note I have not printed this yet but the measurements were taken very carefully.
If you print this, please tell me what you think and how it worked for you.
I will be designing 45 and 90 degree turns as well as T's and four-ways.
Enjoy!!
