Periodic Table

The whole table, not one element. On one plate, 250 mm wide: every cell raised in its group's color, the symbol and number raised again on each, the title and your line where the chart leaves room. Or as 118 wall tiles, 60 or 90 mm each, keyed to one another with dovetails so each drops into place against its neighbours and the rows and columns line up by themselves - and on the back of every tile the same card of facts, so a student can walk up to the wall, lift iron off, and read its configuration, its melting point, its oxidation states, then put it back. Picture strips or magnets hold the tiles on; the keys keep them straight.

On the plate it goes under the title; on the tiles it is the last line of every card. Up to 24 characters.

How it's made. The plate is 250 × 134 × 4 mm, made flat with the back on the bed: the cells stand 0.8 mm off it in their group's color, the lettering 1 mm more, two keyholes and the maker's mark cut into the back. The tiles are the Periodic Tile (60 or 90 mm, 6 mm thick, the lettering 1.2 mm proud), each with a dovetail tab on its right and bottom edge where the table has a neighbour and the matching socket on its left and top, 0.3 mm loose, so it registers against the tiles already on the wall. The back of each carries the same nine-line card, set 0.8 mm into the back and filled flush in the lettering color (the first layers on the bed, the way the formula tiles are made), reading the right way round when the tile is turned over: number, name and symbol; the electron configuration; group, period and block; the category and its state at room temperature; melting and boiling points; density and electronegativity; first ionization energy and the common oxidation states; the year discovered; your line. Above the card, a pocket sized for a Command picture strip (the hook-and-loop kind, so the tile pulls off and goes back), or two recesses for 10 × 2 mm magnets. The 90 mm tile is the one to read from; the 60 mm card is small type. The set is made bed by bed, a color at a time. PLA, no supports.
