Copying this from reddit. I am not OP.

Hello All! If you are planning on coming to 3DPrintopia in Bel Air, MD on September 28th and 29th this year, please consider printing, signing, and bringing along a blue tile for the “Layer Connections” Community Art Project. Spearheaded by stlDenise3D and 3DPrintBunny, the project has already collected roses at the Midwest RepRap Festival (MRRF) and the Rocky Mountain RepRap Festival (RMRRF). It’ll be making a final stop at the Sanjay Memorial RepRap Festival (SMRRF) at the end of the year.

More details on the project and links to the STL files can be found here. The main stipulation is your tile be a shade of blue. Come 3D Print with us! A Community 3D Printed Art Project ⋆ stlDenise3D https://stldenise3d.com/come-3d-print-with-us-community-3d-printed-art-project/
