Bed knob for flashforge guider 2

Here is a bed knob that I designed for different thickness build plates on my guider 2s
I printed mine with 3 walls out of ASA.
If you have the Blue flashforge build plate, you will know how hard it is to remove small prints.
I use a different plate that I got from Aliexpress for small prints, this is a thinner plate that needs re-leveling when I use it.
Now when I switch plates, I can just turn the knobs to the other markers and I'm good to go.
I do re-run the leveling program just to make sure that everything is still ok, it saves a lot of time with these knobs.
The tiny markers can be a little fiddly to get in, I put mine in near to the top of the slot and slide them down, I use a small
Knife in the bottom of the marker for getting them back out if I need to reposition them.
You may need to mess with the sizes a little if you are having problems with the fit.
