i Started by creating the three squares first and then added on the circles after i had all of the solid objects i created cut ones to get rid of the ecces material.
to begin you want to create three squares after that you need to create 4 cylenders and then four cutting cylenders and place them inside the middle of the solid finally place some cutting squares at a 45 degree angle where shown above.
i learned about making new ways to create new objects. it was very difficult thoughconsidering i am using unfamillier softer to create new objects aswell as not being able to do everything due to limited resources at home because of the COVID-19 virus.
