Update to the previous version to allow for printing in PLA. I've also included 3 different 'front' pieces, to allow for printers with different tolerances. The pitot tube is 4mm in diameter, so there is a front with 0.1mm tolerance (what I use on my Up Mini), 0.3mm tolerance and 0.5mm tolerance.
base v1.9 has been added, which features protrusions that will prevent the pitot tube being pushed into the back wall, and kinking or cutting the tubing. This was suggested by Lorenz Meier. The downside is that it's more difficult to feed the tube through, so I've kept the previous version availible.
