Knife sharpener - Wusthof whetstone

Custom made for my Wusthof whetstone (ref 704773), here is my sharpening device !
Inspired by some i found here, i made my own, according to my tastes and needs.

I purchased the stone online on knivesandtools (24€ + shipping) , very happy with it, but wanted to be more precise while sharpening my knives, so ... here it is.

Stone sizing : 150mm x 50mm x 24.5mm
Tube used : 10mm aluminium (pretty close to 3/8 inch)
Bolts used : M5 (and the nuts fits tightly, no need to glue them) and small wood screws for stone holder.
Magnet used : 10mm wide, 2mm thick. (a bit tricky to fit them, but once in place they won't move.)

You'll find two "angle parts", 20 and 25°.
It'll help you calibrate the device for the angle needed.
(Knives are usually sharpened between 17 and 25°, depending on the origin and need of sharpness. The thinner the angle, the sharper it gets, but wear faster)

I uploaded all the STL files, as well as the assembled part : don't print it !
You wouldn't be able
