WHAT YOU NEED:
Why sugru is good for this:
1: bonds to ABS brilliantly :)
2: bonds to most other materials
3: you can remove sugru from most non porous surfaces without leaving any marks
Take note: Unlike LEGO, sugru isn't a toy. While it's still soft and squidgy, sugru is for grownups, not kids, so keep it away from those little guys. Once sugru has had time to cure, it's safe for everyone.
Step 1: Step by step
I recommend that you use the flat pieces and the small double piece is perfect for this project.
1: Make 2 small sausages of sugru the length of the LEGO pieces.
2: Press 1 piece of sugru firmly onto the back of one LEGO block and the second piece onto the front of the other.
3: Make a mini pyramid from the sugru with your fingers. (This will help you get a good bond in the next step)
4: Press the sugru firmly onto the end of your USB cable and the other onto the side of your monitor making sure you get a good bond.
5: Finally, gently press the sugru around the edges to get a nice surface finish.
5: Leave both to cure overnight.
