Acts as a spacer for the wall panels of a Leapfrog Creatr; prevents bending of the panel and allows one to tighten down the screws completely. Especially useful for the front panel -- on my printer it was slanted when screwed on.

The positioning of the hole may need work.

Used 123D Design from Autodesk.
I measured the space using a digital micrometer and replicated it in 123D Design. It is 2.5mm thick, which was ideal to fix the slanting of the front panel as mentioned.
