It is about 20 cm long and 8cm tall designed to have a stepper one end and a tube through the middle.
It warped and the darker discolouring at the bottom is where I used a hot air gun to flatten it!
It is made with ABS
I had my whole extruder assembly come loose in the last part hebce the unfinished flattened top.
Also It lacks strength as the layers are not close enough together.
