Ijon really did an absolutely incredible job :) I basically only gave him the technical parts and a VESA mounting bracket (http://www.pearl.de/a-PX2528-1256.shtml, with additional weight distribution via https://www.amazon.de/gp/product/B008KL739C/) plus my idea of how it’s supposed to stack together, and he took it from there; creating CAD drawings, selecting and sourcing the wood after discussing the type with me, always keeping me in the loop while working on it. I really enjoyed the cooperation and can highly recommend him!
For reference, this is what it looked like before:
