Ruixin Pro III Modification

So The Ruixin Pro 3 is a cheap 21€ Blade sharpener.
The ZY Joints in the Orginal Ruixin are shity, give something about -3 ~ +3 angle tolerance while using...
Also the shaft has no real linear bearing, you can lube it but the shaft will still get wrong out, so even ABS bearings are a great benefit.
And, It is unstable with longer kitchen knifes when you dont nail it on a board or something.

I wantet to fix it, and see how far i can get with it.
Overall it will Cost ~32€, i guest.... i dont know how much the metric Parts cost me, couse left overs.¯\_(ツ)_/¯
