I'm pretty new to the modding community, but I just thought I'd post a few small tips that the other newbies might not know
Dremeling is an art, I need suggestions to further my craft. lol
Any suggestions to refine this process are welcome!

When dremeling plastics I always draw the cut onto the piece, then tape and redraw the design onto the tape. I then really roughly follow the design about 3mm on the inside of the line with a cut off wheel, then pry the interior piece out. After I use a small rounded sanding bit for the dremel to remove up to almost 1/2 mm - 1 mm of the line. After that I remove the tape, to reveal the drawn cutout still drawn on the piece. Then I use a coarse sandpaper (100 grit-400 grit) to remove right up to the line, and a high grit paper to smooth it out.

Something that I have found that helps me a lot is to salvage spare metal case parts, and bits around the house to use as sanding 'boards.' i.e. I used adhesive sand paper and stuck it to an old 5.25 cover, and use it to sand flat surfaces. I also use a flat cover for my usb connector for small flat surfaces, an old marker, and maglight for round surfaces, and a metal psu connector for beveled 90 degree angles. I know these are probably available at stores, but I'm cheap, and they work surprisingly well for the job.

That's prolly the best dremel tutorial out there, by our own favorite professional modder.

Read that this afternoon before doing a custom cover for my nexus Ahh, inspiration... Great tutorial though!
