Ender 3 Hot End Fix Spacer with tube guide

thingiverse

I had problems with the original spacer that the short tube inside the hot end didn't line up with the center hole, since it had a slight bend. It is the exactly same spacer, but with a 1mm deep guiding hole for the tube. The short tube for the hot end in turn needs to be cut to a length of 32.2 to 32.4mm. This has worked perfectly so far with trying out TPU printing as it clogged the whole hot end every time I tried before.
