This is a design by Samuel Wilson. It was designed for a youth pumpkin chunkin' competition as part of a fall festival activity. These designs are scale versions of the real thing that we are building for the event. They printed nicely on my 3D printers as well though and posed as a nice design exercise for the youth in preparation for the final build. Pieces can be assembled with glue, string, and various rods, etc. as you see fit. I will try to get an update posted with actual pictures of the 3D printed models we built as well as the final working wooden construct, hopefully with video of the event as well.

I printed most of the parts flat on the bed so they don't need much in the way of tuning or supports. A few parts can be printed in various orientations but need supports in most layouts but only a couple parts need this.
I recommend sticking with a more forgiving filament such as PETG or ABS for the strength and flexibility. PLA should work fine for most parts but may crack if too much stress is put on certain parts.
I also dropped the ladders down to the supports on the rung side. In real life, rungs will be nailed or screwed to the 2x6 beams. For 3D printing, it's more of a visual effect and doesn't supply much additional structural integrity from a model perspective. I still recommend printing them but if you drop the rung side below your Z a few mm down to the rung supports it will print much easier and won't require supports.
Some items you will need to print two of:
I also recommend printing the basket with supports everywhere but in the holes. It prints best on the front or back edge since the "handles" or "legs" can break at the layers when adding weight if not printed longitudinally. If putting some notable weight in the basket for scale testing/use, you may want to line the inside with a hardening epoxy or something that will help secure the layers so they don't split when swinging. This was not an issue for us in testing since I printed very thick and strong layers but the basket and the swing arm take a lot of strain focused on some potential weak points.
