Wall mounted whiteboard pen holder

Step 2 Construction

Because the plastic was only 1mm thick it is very easy to work with, to cut it to size simply requires scoring both the top and bottom using the knife, then resting the seam on the edge of the table and placing the steel ruler on the top, you can then simply snap the plastic along the seam and get a perfectly straight break. The 3mm plastic is worked in the same way, although you have to score it more deeply and apply more force to it to break it. For your own safety you should wear protective goggles and gloves when doing this stage.

The top piece measures 12cm x6cm
The back is 12cm x 3.5cm
The sides are made from a single piece measuring 6cm x 3.5cm cut in half diagonally
The 2 supports are made from a piece measuring 5.5 x 3.5 cut in half diagonally

The holes in the top are drilled using a 16mm drill bit and are spaced as shown in the photo.

The "keyhole" mounting holes in the back are made by drilling a small and large hole next to each other and using the small file to join them together into the keyhole shape
