F-Bomb

F-Bomb by tbuser Oct 22, 2011

Description

That's F for Flower. A PVA water soluble weapon of mass foliation. Otherwise known as a Seed Bomb deployed by ninja gardeners to sew seeds in hard to reach places. See Also: guerrillagardening.org/ggseedbombs.html

Sure, there are cheaper and more efficient ways to do this... but... pfft... The idea is to stuff it with some compost and seeds and then throw it somewhere that you think could use some color, but you either can't get to it or it's where people wouldn't appreciate seeing you digging around. Then wait for mother nature to dissolve the shell and make some magic.

This of course requires water soluble PVA makerbot.com/blog/2011/02/21/makerbot-introduces-water-soluble-3d-printer-filament/ since you don't want to wait a thousand years for ABS to go away. I'm not even sure this will work, however PVA is supposedly bio-degradable eliteanglingproducts.com/PVAEnvironment.asp and is used as a seed coating celvol.com/sekisui/sek_seed-coating.htm so hopefully it's safe. However, I will assume it's not safe, I'm stupid, and advise you not to do this. Also, I am not responsible if you get arrested for defacing someone's private property with beautiful flowers. :)

However, I'm going to test it anyway (did I mention I'm an idiot and you shouldn't do this?). Unfortunately it's not the best time of the year to try it, but I loaded one and sat it in a pot outside. I also sat one in a pot indoors that I'll run some water over whenever I water my other plants to see how it dissolves naturally over time and if anything grows out of it. I also threw some of the seeds into another pot just in case these old seeds are no good and to compare the growth. SCIENCE!

Alternatively, you could print this in something other than PVA and just use it like a little box to store things in...

Love it! I plan to make a dozen and fill them with lovely mixed seeds and give them as Christmas gifts. I only have ABS but the bomb becomes a keepsake or re-usable ammo case for the F-ammo ;)
Any chance you could make one so the base is the same diameter as the body and the symbol is completely sunk in? I have some clear tubing with caps that I want to fit 3 bombs in and have a nice clean look. I plan to do a multipack.
Great job! very clever

TY!

I've found PVA behaves a lot like PLA. I print it on blue painter's tape with the heatbed low, around 50 degrees.

Hi T. When you're printing just PVA, do you heat the bed? What temp? TY!

Maybe I should fill it with baking soda and vinegar...

Nice job. You could put some small holes or slots in it speed the process.

This is so cool. It's also exactly the kind of thing I'd build, fill with dirt and then forget in my pants pocket until it has gone through the wash ;)

Still tweaking the .15 layer height settings. I've printed a few of these now not for the flowering possibilities but mainly just for the comedic value and detail. In my pic you can see the failed spotty/blobby print and then the currently best print. Thanks for this file, it's a great one to test the detail possibilities of my ToM.

Jeeez.... Clouds, stuff and a self proclaimed Idgit. Oh well. I'm gonna expand on your single good idea into two ideas.

I've got crows. They are noisy. ugly, obnoxious and scare all the little critters away. I'm gonna git my bot back together. Get some PVA (where?), print some bombs and then fill with soil and cool plant seeds. Then, with a new (hmmm printed?) sling shot I'm goin huntin crow! And if I don't hit'em
I'll at the least satisfy my distaste for crow and I'll be planting good will around the neighborhood. ;-) lol....

After 4 days they're already showing signs if dissolving:

F'ing awesomeness!

for full effect this should be combined with a potato cannon. might need to beef up the seam a little at that point though ;)

zgbot on Oct 23, 2011 said:

its the best time of year to try this! see if its broken down by the time spring rolls around.

tbuser on Oct 24, 2011 said:

Looks like it'll breakdown a lot sooner then that! 2 days later and the bottom of the part in contact with the moist soil is already really soft and it hasn't even rained yet.

At first I thought F-bomb meant you'd store a fart in there and ask someone special to open it. I know, my inner child
—wait, pull my finger.

Soon to be your outer child?
