Fixture Block

I started out with sketching the side profile, making sure that all the measurements were accurate. I then made it into an extruded boss/base. Secondly, I added the extruded boss/base circle going through the front top part of the model. Then, looking from the front and top plane, I made an extruded cut towards the right side of the model without going through the entire model. Then, I added an extruded cut, which only went 20mm deep into the left slanted side of the model. Lastly, I inserted two extruded boss/base circles on each side of an extruded boss/base straight slot, and used to fillet tool on the edges.
