Pegboard Pieces #9 - Plate Lock

This is part 9 of a set of laser-cut marble run pieces designed by Paul Buckley. The full 3D model can be found in Onshape [here](https://cad.onshape.com/documents/d0ca1ed3c4aad2fa89b94963/w/c0695c6c5231cabe690a5099/e/b3500dd2100c536b02b61b23).

These are designed for a pegboard with 4.8mm peg-holes, arrayed with a horizontal and vertical displacement of 31.9mm. A curf of 0.28mm has been taken into account.

This piece attaches to the end of a horizontal plate to tighten the peghole fit.
