Hi this is my first instructable.
Step 1: Gather the Parts
Old transformer (From junk)
Hot glue stick. (1)
(you could use hot glue gun instead of lighter)
Step 2: Pull Out the Plates
Take apart the transformer and save the plates.
Story I didn't took the photo of this process.
Step 3: Bend the Plates
Bend the plates as shown in the photo.
I used a heatsink for holding it in place.
Step 4: Mark the Positions and Place It
Place the glue as marked.
Stick it to the shelf.
I used 3 of them.
Step 5: Finally
Place a cardboard or glass sheet tight on the plates.
if the board is loose the plate may come off.
