Signing UpStep 1Measure, Mark + Cut the Concrete Form
1.2 To help support the plastic container while cutting, cut a styrofoam block ( about 3¾" x 3¾" ) and push it in the opening of the form.
1.3 Starting from one corner, gently saw back and forth to start a straight cut. Go slowly at first, alternating back and forth between corners until you can connect the slices and cut through. Repeat on the remaining sides until the cut is complete.
1.4 Clean up the edges of the plastic with some rough sand paper ( 80-100 grit ) and be careful not to scratch the inside of the form (any scratches WILL be transferred to the concrete).

Here's a version with the shelf made from beech wood holding a samsung galaxy tablet. All the best,
