Logitech Performance Mouse MX wired mod
Charging batteries sucks and the cable provided with the mouse was way too stiff for every day use. I still wanted this mouse for having the Darkfield Tracking and Endless Scrolling features.
Here is how I did it: Logitech Performance Mouse MX wired mod @ Instructables
For integrating smart switches into my existing electrical installation while still looking good, I designed a Jung AS light switch plate @ Thingiverse, prepared for the Anarduino modules.
Non-Sucking 3D Printer
With my old Velleman K8200 3D printer, I got a lot of experience and learned a lot about how a printer should be and where the problems usually are. At some point, there was no use further improving the printer because I would have to do major changes to the mechanics. So I decided to create a new one, from scratch.
It doesn't live up to its name but maybe you can learn something from it: Non-Sucking 3D Printer @ Thingiverse
Non-Sucking 3D Printer MK2
As its predecessor didn't live up to its name and had some flaws, I again learned a lot about how not to do it. And then E3D released their idea of a tool changer into the wild. This was just too intriguing - so I decided to create a new one, from scratch. Again.
It is done-ish but will receive an update when I get the "direct drive" tool done: Non-Sucking 3D Printer MK2 @ Thingiverse
