About this 3D model

Hi there! I needed to make a few holes around the house to make some installations and dust was an issue. Decided to design my own guide and dust collector to make it look the way I wanted. V2.0 There were several changes from the previous version. My old model is quite popular so I had a lot of feedback. Some people commented the main guides were breaking on them, so I tweaked a little the design to make them stronger, as illustrated below. Another new feature is I added some little rulers into the design. Left hand is a small 50mm ruler and the right hand is a small 2 inch ruler. And finally, some aesthetic modifications, I really liked the result.
