About this 3D model

I recently purchased a Dewalt Model DCD777 but it had no magnetic bit holder, or any bit clips. I noticed that it DID have the screw holes and nylon locking nuts for a belt clip. I am extremely new to actually making things to print, but really felt that I could make something that would fit this drill. This is the first go and there may be some modifications to it. The magnets I used are from Harbor freight then come in a capsule and are 8mmx2mm; simply glue them in place with your favorite cyanoacrylate or hot glue, they are hidden behind the face of the holder so as not to damage the magnets. The screws are M3x15 cap head screws you can get from any big box hardware store.
