Thanks, guys. I started the second door enclosure, but the progress is not that much. Working after work is freaking exhausting. Anyway, small update with my new shifter ball. Old and ugly, that screw right through it ..ugh. Fixed a bit the metal threading. 5cm diameter, love the feel it has. I'll have to water sand it with the finest grit I have and polish it with wax. The metal rod was rusty, but nor was my battery enough neither you need a pic to image it. Spend some time with the water sand paper and it's like new. Next to the gear project - grooved gears.
