K40 Air Assist - Mix and Match

thingiverse

Mix and match your tube size according to your preference. A 4mm attachment is included, suitable for most coiled air hoses. To secure each part firmly in place, apply super glue from below once it's seated. Adding a bit of baking soda will speed up the process instantly. Be cautious not to put any glue on the inside of the assembly; we want to keep the hole open. A 6.6mm cylinder is also included, allowing you to find the correct hose fitting in the Fusion 360 McMaster-Carr parts catalog. Split and attach it to the peg for a secure fit. To reinforce the main body, use two 3.5mm screws to help hold everything together tightly. I've added a female attachment for the hose as my previous one snapped off. Now, the hose can be inserted instead of being placed over it, providing a more reliable connection.
