Replicator Layout Grid & Glass Holder
by LeftAngle, published
As Comedian Jack Black says; "This is hard"
This grid replicates the layout grid illustrated in your ReplicatorG file and puts it onto your real-life build platform. It makes it far easier to determine where on your platform the build will take place. I believe Makerbot's build platforms are made one at a time, so this is file is dimensioned to fit my plate.
if you use glass as your substrate, it's common practice to clamp it to the aluminum platform with spring metal clips.
Clips sit above the build surface and require careful planning on where they're placed. Also, glass isn't a perfectly rigid material. Glass is actually quite flexible and if your aluminum plate isn't perfectly flat, glass will take on the plate's shape when it's clamped to it (thicker is better here).
The holders in this file sit below the build surface and hold the glass by its sides. No vertical pressure is applied so the glass stays completely flat.

The grids install from underneath the build plate and are held on by the corner screws. I've made additional parts to help glue the pieces together. If you print these in a contrasting color, they'll replicate the center lines in ReplicatorG.
The glass clamps may need additional work to fit your situation. The parts will work with 1/4" plate. Modify the file or file them down to fit your glass thickness. Just insure the finished clamps sit below the surface of your glass. Otherwise, bad things will happen if your extruder happens to wander into a corner where you've placed them.
I printed complete grids for myself with the intention of using the 2 best for the front and putting the less perfect prints to the rear. Those 2 will need to be trimmed to miss the power cable plug.
Now, this is the part I was referring to about being hard. Glass plates come in all sizes. When I cut mine, I went slightly larger than the aluminum plate. Everyone's experience will differ here. The photo shows the system I've ended up with (at the moment). I've provided the clamps I use in the file. If it they work for you, great... If not, experiment.
Either way you use this, as a grid alone, or as a way to hold glass build plates, enjoy.
