So, the PTFE tubes on all my toolheads sag and bend pretty bad… Especially 3 and 4. Toolhead #3 gets dangerously close to obstructing toolhead #4.
What have others done to remedy this problem?
I have considered something like this, but curious if there are other solutions out there.
or something like this one:

Do you think that printing both items and putting them in use is practical?
I did, but worried the tensioner puts too much strain on the toolhead. I’m definitely going to try the second file (tube holder) and see if it does anything positive.
I would definitely remove this additional orange cross-connection. In my assessment, it only placed additional strain on the overall system and offered no advantage.
I don’t understand how something could get blocked on your end. After all, only one head is active at a time and cannot overtake the other heads or become entangled with them.
I have secured everything on my end with the included clamps, and so far there has been no blockage or dangerous situation.
If the hoses or mounts become worn after a few years, they will simply be replaced. If they fail before a certain service life is reached, I would contact Snapmaker.
The cross section is the whole point of the model… Read the description.
But, I have no problems yet. Toolhead 1 and 2 sag to the left, Toolhead 3 and 4 sag to the right. Toolhead 3 sags to the right more than Toolhead 4 does, therefore it gets close. I don’t anticipate them ever really “tangling” but could cause increased friction or resistance.
I’m thinking something like a loose spring, just to stop the tube+cable sagging. OK, so that’s probably not something you can print, but…
The ptfe tube holder in the second file works pretty good, I’m not going to try the tensioner.
A simple solution might be tape or twist ties. I have used twist ties to hold cables etc. in place and they are easy to remove.
