Unfortunatly the first print is a waste of plastic. It toke me a while to understand why there was so much friction... Bearings on, spindle not touching anything, design almost identical to the original...
Except for the 1mm you removed!! :-((( The original design offer a 115mm long cavity, yours is 114. Either you did not notice and maybe your extrusion ratio is fine with that, or you adapted and should tell :-)
That being said, very nice adaptation, I cant wait to see the fixed one ;-))
