may be a bit longer i found my long walletmore needle and a shorter commercially available one, so ill be making 2 concept models. im currently sercoming to printers size tolarances, ( adding and removing 0.1mms for that perfect fit lol. i have no chance of printing that thread mechanism on this printer, at 1.5mm thick its not gona hold shit.but like you said theres surgical glue)
theres about 20mm between the 2 needle sizes, so ill also compensate the plunger 20mm,
Please ignore the yummis on the needles. We all know where they come from
