Half Size Gridfinity Base Flat Filler Plate Covers

This is a collection of Gridfinity flat cover pieces for a base plate, using half sizes. There are other models for whole gridfinity unit plates (see https://makerworld.com/en/models/987047-gridfinity-filler-plates-tiles), but none for half-size units. These flat pieces can act as filler on a Grifinity base plate or allow you to set other objects in position, which can't be adapted to Gridfinity. 

These are provided in half-size increments from 0.5u to 6u, with a 5.5x6u plate the maximum provided here (using standard 42mm unit grid). No whole by whole unit models are provided here, but there are both half-size x whole and half-size x half-size (some corner pieces). 

Parametrically generated using options on the basic cup OpenSCAD script from the excellent Gridfinity Extended OpenSCAD collection. Particularly a height of 1 with filled_in true, and no rim. The slightly modified openscad script is included in models files. None of the other bin collections I found had these, so I hope they are useful to you as well!
