I am still somewhat new to Maslow. My wife has been flying through a TON of plywood already!
I went with the 2l bottle setup for my slack management so cant help you much with the bungee system. I would steer you away from wasting too much time with the OEM router adjusters. I would HIGHLY recommend upgrading yourself to the Meticulous Z (or similar)as soon as you can. Meticulous Z-Axis link
The router brackets are easy to draw for different size routers if you have something else you want to run on it. The plans also include provisions for a really well contained dust collection system. The majority of it is set up to be cut out on your router and the rest is on Amazon. I think my total cost was well under $100 for everything including the plastic sheets. I have a large 3d printer and printed the dust collection duct. Plans for a plywood version are included as well.
