Milwaukee M12 Jigsaw 2445-20 Vacuum Adapter
These are vacuum adapters for the Milwaukee M12 Jigsaw model 2445-20.
The vacuum port is for a 32mm hose end and discharges between the battery and the saw. There is a left discharge and right discharge version for whichever grip is convenient for your project.
I printed this with the vacuum port surface on the build plate to maintain good diameter consistency at the vacuum port and minimize the supports necessary inside the part where it is difficult to clear them out.
I used tree supports in my print.
