Description
These include a space perfect for a UK penny inside to add enough weight to hold down one or two light helium balloons (your mileage may vary :) ).
Add a pause or material change in your slicer to use the multi-material options and fit the penny if needed.
Included a sliced plain star with concentric infill.
