riverraid's "wall mounted keys and masks hook" remix

I liked the design of riverraid's original, but after printing it, I noticed – after a lot of difficulty inserting the pegs at all – the tolerances were so tight that the pegs were warping the base plate.  I loosened up the tolerances by 0.05mm each side, as well as moving the slots you insert the pegs through to the top of the model so that gravity naturally holds the pegs in their pivots, making it impossible for them to fall out from sloppy tolerances or work themselves loose from being opened and closed.

only the base plate has changed; the other parts are identical to riverraid's original, uploaded again here for convenience.

small disclaimer: though this is a remix, I had to remodel the entire part from scratch because riverraid only uploaded STL files and onshape can't do much with those; I haven't tested the geometry of the screw hooks in the back (mine is stuck to the wall with adhesive strips) but I tried to mimic the original as closely as possible.

looser tolerances; the slots through which you insert the pegs are on the top rather than the bottom, so the pegs are held in their pivots by gravity instead of friction.
