¶The two measurements to take
The gap first: slide a ruler behind the radiator and measure the horizontal distance to the wall. Then the thickness of the board you will lay on top. Those two figures point to one file in the table provided.
¶What is in the pack
Thirty STL files. Six board thicknesses, 15, 18, 20, 22, 25 and 30 mm, crossed with five wall gaps, 20, 25, 30, 35 and 40 mm. A text file gives the print settings and the full selection table.
¶Air keeps moving
The gusset holds the board 60 mm above the radiator. Warm air rises between the two, and your board rests on nothing hot.
