I am trying to restor a vintage wireless that has elastic rubber valve retainer straps (see picture). These straps have to be stretchy like elastic bands and whilst I bought some TPU super flexible and printed a perfect replacement it IS NOT “incredibly elastic” At 2mm thick it is impossible to get any longitudinal stretch whatsoever!
And yet the seller says:-
The TPU A95 has been specially designed to make it perfect for 3D printing applications. TPU A95 is a flexible filament with incredible elasticity.
However The ‘Shore’ rating of elastic bands is somewhere around 30A - 40A and this TPU is A95.
Sop my quwstion is what £d printing filament is stretchy enough to print rubber bands?
Thanks in anticipation
