As a side note, I tried to make a new intro video. But I have to admit I'm not sure if it's a good or not. Feedback is well appreciated. And, yes, no money was harmed on shooting. ;-)

To start with Sugru, I decided to hack something easy and useful. I have been using this Kodak Zi-10 1080P pocket video camera for making my youtube videos for some months now, and all in all it's really nice thingy.

In simplified terms, it's yet another kind of moldable plastic. I would say it is kinda like self curing silicone, freshly out from the bag it's soft to handle and sticks well to various materials. During some hours at the room temperate, it will dry and Sugru become rubbery like material.

This is something I was looking for some time ago and could not find one from any shops. A simple hook that will hold the kitchen towel right where I need it.
I used to keep the towel folded atop of the cupboard door, but it tends to slide of and drop to floor. With this simple hook, the towel won't fall, but it's easy to access. And when printed with clear PLA it next to invisible.

I have finally decided to start making new parts in purpose of fixing the on/off issue of this printer. With Bowden type extruder, there is always a risk of the bowden-tube been too stretchy or getting lose.
At Emaker Huxley, this 3mm PTFE tube is attached with an Pneumatic connector, which is nice and quick way, and does usually work reliably enough.
