Plastic Bottle Base:
I would look in the kitchen or grocery store for a round plastic container where the cap fits the plastic bottle base.
I used a 1 quart plastic vinegar bottle for one and a plastic beverage bottle for the second. Remove plastic safety ring. Drill 2-1/4" holes through bottle side (and cap if necessary) about 5/8" from the end of the cap. Location of holes will will determining liquid height. Liquid closer to the bottom of the flower is best.
Wine Bottle Base:
Used a cork type wine bottle. Just push the open end into the base. The base will provide about 7/8" of liquid in the bottom container.
I printed a flower @ 60% speed for about 12 minuets and then reduced to 40% speed for the stem. Slow speeds will give better results. A timer will help. Flower #1 has smaller petals and are for bottle clearance when necessary.
Tapered Mounting Rings:
They have a relief for getting closer to the lid edge. 2 per flower.
Plastic Bottom Container:
Need a shallow container about 1-5/8" deep. Tupperware or equal will provide the most durable container. Drill 1/2" flower holes in the lid far enough in from the edge to clear the bottom part of the container when put together. Center hole should be large enough to allow the bottle base to sit on the container bottom.
Knob sticking out of top bracket is for recessed container bottoms. Reverse for flat bottoms. Brackets were printed at 80% speed.
Cut one piece of the appropriate length and a second one twice as long. Double the long one and knot all three strands to form a knot with loop. String the hanger brackets and knot or use Cord Lock.
Cord Locks were used on the wine bottle build. Be sure and secure the cord back around the lock for safety after all is adjusted. They can be found at this link.
Cleanup necessary. Print speeds will effect the final fit up. Used crazy glue where needed. Scale for you needs.
Liquid is 1 part sugar to 4 parts water. Most Hummingbirds have a tongue as long as it's bill.
