Inspiration: Dr.Johnson had wanted a rack that could specifically fit small 0.7 diameter tubes for her class to use. This seemed easy enough to accomplish so I took up the task.
First, I sketched a rectangle on the xz plane and extruded this in the + y direction.
Then, I hollowed out the inside and, using a rectangular pattern, sketched an array of circles on the top.
Next, I cut holes all the way through body using the circles as the cutting tool. I did this twice so all 4 sides had holes cut through them.
For the finishing touches, I filleted the corners by 5mm to give it a finished look.
(For this particular print I cut off one base using a construction plane because it saved 4 hours on the print and was not necessary for the purpose it was going to be used for anyway.
