Zen sand garden - pit and pendulum

Use no supports!

The arch structure should friction fit in the base.  Supply your thread or string to hang the pendulum.  It is fun to play with, sliding around gently on the table or desk to create patterns. Fill with sand, salt, sugar, or whatever!  Printed in PLA at 0.20 layer height, 0.4mm nozzle.

I only needed about 10% infill to make it a quick print.  The parts should fit on anything with a bed of about 160mm.  I printed the base independently and then the arch structure and pendulum together.

For an optional bit of fun - use gyroid infill on the pendulum!  Pause the print at about layer 60 (my count using 0.20 layers) and fill the pendulum with sand, salt, etc., for extra weight.  Then, resume the print job.  By about layer 70, it will cover and seal the contents inside.
