Hi all,
When I first bought my Etherwave Standard two years ago the seller forgot to include the coil adjustment tool in the box.
Because I am an idiot I decided to ignore the manual and adjust the coils with a small hex key.
Naturally this eventually cracked the inductor slugs and I had to desolder and replace them with new ones from Coilcraft.
In order to save myself and others from the same fate I designed a tiny 3D printable knob that can be used to tune the inductors; it can also be left in permanently and used to adjust the slugs on the fly. You may not wish to do this in case it makes the slug position more sensitive to vibration in transit, etc., but I haven't had any issues.
Even if your 3D printer sucks, the dimensions of the hexagonal bit at the end don't need to be exact for this to work - the texture of PLA "grips" the ferrite well enough.
Disclaimer: I would hate to be responsible for someone cracking their slugs with this model! There are plenty of dimensional inaccuracies between printers, so if you try this, install the knobs gently and carefully and don't force them in if they don't fit - just scale down to 95% and print again.
Hope this is helpful for someone.
Edit: just noticed it didn't upload properly to Thingiverse properly, I'll update this next time I'm at my home computer.
