External AMS Buffer Support

With the arrival of my second AMS, I encountered the challenge of positioning the AMS units to the printer's left. This wouldn't have been problematic with ample space, but it unfortunately encroached upon my workspace.

Thus, after thoughtful consideration, I slightly reorganized my workspace.

I situated the AMS stand to the table's left, leaving the central area open for unhindered work, with the printer positioned on the right.

My difficulty lay in the buffer's design, which is optimized for AMS feeding from the right, as otherwise, significant bends are introduced.

This component provided the solution.

It secures via pressure to the worktable (in my setup, the hold is more substantial due to rear wall contact). With a mere 30cm PTFE extension, the feed line is perfectly aligned, ensuring a unidirectional flow without forced curves.

Beyond the recess accommodating the buffer's tab, two insertable M3x4.2x4 nuts further secure the buffer.

Prior to uploading, I rigorously tested this setup, including prolonged prints, shorter prints, and multicolor prints, without any issues.

NOTE: The nut holes measure 3.75mm in diameter, a deliberate choice to ensure a snug fit and prevent tightening difficulties. This, however, results in significant plastic displacement during insertion, though easily remedied with a blade.

With the arrival of my second AMS I ran into the problem of having to place the AMS to the left of the printer. There wouldn't have been any problem if I had had space but I found that it was invading my work area.

So, on reflection, I rearranged my workspace a little.

I placed the AMS stand to the left of my table, in the central part I left space to have space to work and to the right of the table the printer.

The problem I had is that the buffer was designed to be fed with the AMS to the right, otherwise there would be many curves.

I solved it thanks to this piece.

It is fixed by pressure to the work table (in my case the fixation is somewhat greater because it rests on the rear wall) and simply with 30cm more PTFE it left the feeding line well aligned in a single direction. without forced curves.

Apart from the recess to fit the buffer tab, it has two M3x4.2x4 insertable nuts to leave the buffer screwed and well fixed.

Before uploading it, I tested it extensively (long, short, multicolor prints, etc.) and it hasn't caused a single problem.

NOTE: The holes for the nuts are 3.75mm in diameter, the reason is because I like them to fit very tight to avoid problems when tightening. It has the drawback that it displaces a lot of plastic when inserting, but it is nothing serious and with a blade it is easy to remove.
