MPCNC vacuum setup for z-axis (makita/katsu) by DiscoStuso

I designed and redesigned some parts to use the z-axis of my MPCNC Primo as a vacuum pipe.
The top connection is a Remix of this one:https://www.thingiverse.com/thing:3784396
I changed the fixation so it is mounted over the 25mm tubes to get the full diameter for airflow.
Note: The z-axis tubes must be 10mm longer on top!
The nozzle on the bottom are two parts which have to be glued together. The upper part has an integrated windshield to stop the router blowing air downwards. This causes a better effectivity for the vacuum.
I also added a version without this windshield. So, depending on how far your router is away from the center it may fit also for other routers.
Advice: With this nozzle you will loose 18mm of z-axis height.
IMPORTANT: YOU HAVE TO GROUND YOUR Z TUBES! I HAD THE ISSUE THAT THE CHIPS CREATE EXTREAMLY STATIC ELECTRICITY. IN MY CASE THE USB SIGNAL COLLAPSED WITHOUT GROUNDING THE TUBES.
More advices: I used the custom nut wrench attached to the thing i linked to remove the nut traps for best airflow.
I used this antistatic 38mm tube:https://www.amazon.de/gp/product/B07M6B3HVC/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
