Bringing tractors to your hand


This is a gardening tool that was designed with the developing world in mind. In the developed world we have tractors that can generate acres of food at an incredible pace however in areas less fortunate they have to dig a hole put in a seed and then wait. While this may seem easy it is still very slow.

The concept here is to take a tractors planter and make it hand held. A user simply loads the hopper with seeds and then starts to rip row of seeds. They squeeze seed release lever and allow seeds to flow out.

With the design code included they are able to manipulate the size of the hole in order to fit what ever seen needs they have.

Materials and methods

I manufactured the entire product out of PLA on a Delta Bot printer and 1 rubber band. (Athena2) I printed large grey piece by itself using a raft and support everywhere. I also printed the seed control level as an individual print and then the two connection as a separate print. These I only used a skirt. These settings were all setup using the slicing software cura.

I was able to print at 120mm/s and it took about 4.5 hours to print all of the parts. It ended up with a cost of about 100 grams of filament and 2 USD.

To assembly everything I did some plastic non additive welding. To do this I used a hot soldering iron to work similar to a non filler Tig weld. I first put a small piece of filament through the two hooks and the control arm, as a pin, making sure the hooks were the right direction to fit the large bodies curvature. Then using the soldering tip I melted the two ends of the filament pin. Once this cooled I tested the lever to make sure it could rotate freely.

After this came the difficult part. I had to attach the hooks to the large part. To do this first line up the plug into the seed exit hole. Then while keeping the plug in the hole line up the hooks to be square on the large piece. Give the lever a few tries to make sure the plug can enter and leave the seed hole smoothly. Then VERY CAREFULLY using the soldering iron to run a line along the joint of the hooks and body to weld them together. I recommend doing a small dot on each first to hold it in place so you can do the longer line welds without fingers holding the part close.

Finally take your rubber band and wrap it around the handle and fit it into the grooves provided on the design.
