A Mario Bros themed planter. It could hold any small plant, but for the purposes of awesomeness, I've chosen to fill it with venus fly traps. Made from cheap and readily available materials, this would be a perfect weekend project to soop-up your planter profile.
Step 1: Parts
4" to 3" reducing pipe
3" coupling pipe
1/8 inch acrylic
bondo -- car putty
neon spray paint
Step 2: Putting it together
Cut a 2" section of the 3" pipe. It used to tie together the coupling piece and the adapter. Fit the pieces together and if they fit nicely, glue it together.
Step 3: Smooth it out
The pipe comes with annoying logos and and nodules used in molding. I decided to sand down all the imperfections and attempt to get this as smooth possible. There is also a seam from joining the pieces. After sanding down everything, I added bondo to smooth things out and fill in the gaps. After sanding down the bondo, you'll get a pretty smooth surface,
Step 4: Finish it up
Time to paint. I started with primer and then used matte finish neon spray paint. To get a nice shiny finish, I finished it off with glossy finish spray. To get a deep enough color, it took several coats of the neon spray paint.
Step 5: Feed me Seymour
Wash with soapy water to remove any residue from fabrication. Next, get your dirt ready and carefully transplant the fly trap. Be careful not to get bitten when moving. Feed regularly and enjoy.
