Description

In order to fit the 2kg rolls from Prusa, I created this buffer, which is wider than the original that fits the 1kg rolls. The screw hole is at the same place as for the 1kg buffers, but still gives you some freedom to arrange the buffers as you wish. Of course the whole set will now be wider than the Commuity version top. You can have up to three 2kg buffers and still fit the screw holes. (Start with one 2kg buffer, then two 1kg buffers, and end with two 2kg buffers.) In my setup I have two 2kg buffers, and the excess is about 6cm on each side of the top. I printed them in PETG, with a 0.4 nozzle, 0.20 STRUCTURAL, on a PURSA CoreOne. Already the 1kg buffers take a really long time to print; the 2kg variants take about 15h20m plus 12h9m to print.
