"As soon as I saw the picture... I instantly thought 'I know that part'," said Scott Crawford, head of 3D printing firm Revolv3D. "They designed an upgrade for the printer soon after it was launched, and most people will have downloaded and upgraded this part within their printer. It basically pulls the plastic filament, and it used to jam an awful lot. The new system that they've put out, which includes that little lever that they're claiming is the trigger, is most definitely the same part.""
