Thats the main flat band sorted, the rest are less critical.
Original unstretched 285mm x approx 3.5x1.5mm. Area for area, silicone
is more stretchy than neoprene , so about 50% allowance for that, a now
working band of unstretched 250mm x 4x 2mm. Target was 265mm x4x2
,probably turn out to be too tight on speed check and will have to
resort to cutting up my next size up solid silicone funnel as 250mm is
the max,outer ring, for those collapsible funnels
