Firing Tube

Here’s the model of the firing tube.  The large tube is the right diameter for a Ping-Pong ball.  The holes in the sides are where the pitching wheels will go.  The bit off the side is where the motor mounting will attach.

This is printing right now, and it says it’ll take about an hour and a half to finish.  I tend to have bad luck with prints like this.  They always seem to peel away from the baseplate or split at one of the layers.  It if doesn’t work, I’ll try using PLA, which is less like to do that.  Unfortunately, PLA is more likely to gum up my printer…
