A progress report.
The ramp is coming along nicely. After printing the top and bottom ends, as well as the launching trigger with mount it was time to draw the launching carriage. Here is the main spar with bottom end and the launching trigger test fitted.
Since carriage interacts with everything else, I decided to simulate it by making an assembly with the already printed parts in the CAD, to make sure it would work out. After a few adjustments it did, and here is the result:
The launching trigger holding the carriage.
The release catch activated by the release ramp.
And I couldn't resist adding the rocket to se how it looks.
Now on to printing the rest of the parts.
