Ok, so I had a 28' pup trailer in primer, and was feeling good about my latest 3d print results. Then I decided to compare my 28' pup with a Trainworx 28' drop frame pup. I guess size does matter. I had to go back to my design file and found that I did cheat myself by 6 inches on the trailer height. Sigh.
Oh well, that is an easy fix, and I can have another one ordered soon. Anyone need a 13' high UPS trailer?
Overall the quality is great, and the details turned out very well. I think this design is a winner despite my incorrect dimensions. The only downside to this trailer is that it is a pricey print. I made the walls a little thicker to avoid warping, and it increases the cost of the print. The top is one piece, while the frame is separate much like the Trainworx version. Since I have to revise my design anyway, I will reduce the wall thickness to see if I can still get a solid model but less volume and cost. Now that I know I can successfully print a van trailer, a 53' reefer is in the works. Stay tuned.
I took some photos to illustrate my results:
