SummaryI work on MacBooks everyday, so when our school borrowed a MakerBot Rep 2 and I needed something small to put screws in, I quickly designed this holder in SketchUp and had it printed the same day. This was my first 3d design and print. Blue one was printed on a MakerBot Replicator 2 and the clear one was printed on a MakerBot Replicator MiniInstructionsI don't intend for anyone else to print this, but if you do, you'll have to scale it up because I designed this in inches and not mm.
