Enclosure for Grin Phaserunner

I built an E-bike with not so much space for the controller within the frame triangle. So I designed an enclosure for the Grin Phaserunner that can be attached to the saddle pipe.
Follow these steps for mounting the controller:
1.) Plug the cables to the phaserunner; for the programming port, an audio extension cable is inserted to the phaserunner and into the hole on the lower side of the enclosure.
2.) Insert the phaserunner into one half of the enclosure
3.) Align the two halves of the enclosure by inserting a plastic pipe.
4.) Fix the two halves with tape (the wall is a bit thinner where the tape should be placed).
5.) Attach the enclosure to the saddle pipe by means of hose clamps. Shink hose around the hose pipes protects the frame from scratches.
