Because remain some cardboard pieces, from my last instructable, I decide to make some useful thing, not to make more garbage (even if is biodegradable).
Because I nedd a cup support, I want to make more like cut a circle or rectangle from cardboard.
I write less to this instructable, because is very simple, and I repeat some step form last
Why is a green solution? Think if you make more like one piece, for a big companies, with many offices; not only for cup: for pencils, clips, rulers.... All this suport is from plastic materials or metal, and is change frequent (crash or new gift).
Is not only a ecological solutions - is a crisis solutions: replace all nonecological plastic objects with this cheap cardboard (possibly personalized with a green paint). Is not a problem if you throw to trash basket (is biodegradable), but if you trow your plastic suport - this degrades in 150-400 years!!!
Materials and tools:
- remain cardboard pieces, thickness 3,5mm, 240x23mm,
- pencil, ruler
- paper glue
Step 1: Make Project
Fist I make a rapid project, I measure 1 pieces and cut.
I put this piece over other, and draw with pencil cutting shape. Repeat this for all 21 central pieces.
Step 2: Glue and Finish
This step is like Step3on my last instructable: put 2 books perpendicularly, glue every parts and press togeter.
This is all. Now I have a support for my usual tool: coffee cup, pencil and post-it for idea sketch. You can make space for what you nedd.
Is wet - throw to trash and make other in 15 minutes :)
Enjoy and save our planets!
