"Bear Necessities" Tool Kit

For this project, I decided to make a tool kit that someone could take hiking, have as a just incase tool, or use for their dogs. I was inspired when I found a tik in my dog's head and pulled it out with tweezers. Unfortunately for some people I know the head may get left in the skin of the animal or person and could cause infectious diseases. I looked up some tools that would be great to use both in the wilderness in a pinch or to successfully get a tik out of a tight area. I made a forked tik remover, a tweezer type of tool and a comb for miscellaneous uses (hair, sifting through dirt, etc.) My inspiration for the design is a rolling pin my mom had where you can screw on different sized round edges to size the cookie dough. In my design, you can unscrew the sides to get the tool you want off. I will be 3d printing this tool in which I designed on "On shape"- a digital engineering site using the STEM Academy's 3D printers.

First, I made the pole that the items will sit on.

First, clicked top view, sketch, and click the circle tool. Create a circle with the diameter 1.510 in. Then extrude it .5 inches. The reason for this is to create grooves in the pole for the screw on disks to attach. After you extrude it, click on the extruded area and click the helix tool. The helix tool allows us to create the small grooves in the pole. After that click sketch again and click the circle from the first extruded piece. Clicked the circle tool and create another circle with the same area and extrude it 3 inches. After that, click the sketch tool again, choose the 2nd extruded circle face and make another circle with the same diameter. Then extrude that .5 inches and repeat the helix tool maneuver. The final pole looks like image 1 provided above.

Next, make the comb piece. To do this, first click front view and select sketch. Create a straight line sketch that is paired with seven .965in sided triangles with a 10.859 degree angle between the flat piece and the first triangle and 27.778 degree distance between each triangle. I extruded it .5 inches to allow it to be able to comb through finer materials.

Then, I made the screw on disks which will be placed at both ends of the tool, enclosing the pieces. First I clicked the right plane and made a circle with a diameter of 3.012 in and another circle within it with a diameter 1.550 in. I extruded the first circle 1 in and the inner circle I remove-extruded it 1 in to create a hole. I then used the helix tool inside of the hole to create the grooved by clicking on the inner surface.

First, select the right plane and select the "Three pointed arch" tool. Then create a semi circle with the radius of .881 in. From there, go to each endpoint of the arch and sketch a straight line .386 in on each side. Then from the end points of those lines, sketch another line turning inward set to .724 in. in length. After that, make a horizontal line that reads .541 in.- which will connect each side of the piece. Then extrude sketch 1 .5 inches. Create another sketch using the circle tool on the inside of the first extruded piece. Create a circle with the diameter of 1.512in. Then select the extrude tool and click on the second sketch we just made. Select the remove option on the extrude tool and set it to 1 in. The inside circle should disappear, hollowing the piece. The finished piece is the first image provided.

First select the right plane, hit sketch, and select the line tool. Make a horizontal line .5in. Make a vertical line from the horizontal line on each end of the first line reading 2.5 in. in length. Then select the 3 point arch tool and from the end of the line on the left create an arch with the radius of 1.630 in. Select the 3 point arch tool again and create an arch from the line on the right with a radius of .971 in. From the left arch create a line by selecting the line tool and clicking on the end of the arch. Create the horizontal line reading 1 in. in length. From there, connect the arch on the right and the horizontal arch on the left with the line tool. The line should be .921 in. in length. After the sketch is completed click the green check mark in the sketch box. Then select the extrude tool and select the sketch we just made. Extrude the sketch .541 in. From there, select the top plane and select sketch. Create triangles from the line that connects the first piece angled at approximately 8.466 degrees and with the length of 1.011 in. Make a triangles by connecting another 1.011 in. line to the first and repeat it again to create a second triangle. After that select the area surrounding the two triangle areas previously sketched and hit the extrude (remove) tool at a 1 in. depth. The two triangles should be outlined and connected to the tool. The completed piece is the first image provided.

First, select sketch, the front plane and then select the line tool. From there create a horizontal line with the length of .5 in. Then, on both sides create a vertical .25 in. line that connects to the horizontal line. Then connect the two vertical lines with a .5 in. line. After that, from the middle of the second horizontal line, select the 3 point arch tool and make an arch with the radius of 12.360 in. Select the 3point arch tool once again and from the midpoint of the horizontal line create another arch on the left with a radius of 12.360 in. From the end of each arch on both sides, select the line tool and create two lines going up on each side with the length of 1.070 in. On the left side, connect the line just made to the top where the sketch was begun (at the midpoint of the second horizontal line). After that, from the line made on the right, make it vertically 1.061 in. Then, make connect the end of the line just create from the bottom to the midpoint of the second horizontal line. From there, connect the endpoints of the second horizontal line to the 3 pointed arch on both sides with a 36.129 degree space between them. The slanted line on the right/bottom should be .258 in. Click the green check mark. Finally, extrude all parts of the sketch .541 in. Select the Green check mark again. The finished item is the first image provided.

Now that all parts are finished. Go to the assembly tab. If you do not have one, click the plus on the bottom where the other tabs are and select "Create Assembly." Select the insert button on the top of the item bar and select each part previously created. First, double click on the pole and select Fix to keep it in place. Then, have one of the screw on disks on one end, connected with the revolver tool at the top. To do this, click the frontmost area of the disk and connect it to the frontmost of the pole with the "Fastened mate" tool, located at the top. Then, connect the tool attachment piece to the comb, the tweezer, and the tic remover piece with the "Mate connecter" tool in the same plane to plane manner as the disk was connected. Use the "Fastened mate tool to connect the completed tool pieces to the pole. Finally, place the other disk on the opposite end to close it off. After the assembly is finished, select the plus at the bottom of the screen and select "Create Drawing." Then, use the acronym "TIFS" from left to right and top to bottom, placing the different views, "Top, Isometric, Front, and side (either left or right). Then name the item on the bottom and label the date it was created.

In order to 3D print, you of course need a 3D printer. I used a Bambu Lab printer with Bambu Lab-issued filament. I used the Bambu Lab slicer- which is an online plate that you digitally align your pieces with and put them on the virtual printing plate which shows you how they will print on the printer. The printing time lasted about 3 hours. After the print finished, use gorilla glue to piece together the tweezer, tic remover, and comb pieces to each circular attachment piece. Let the glue cure and dry overnight and came back the next morning. Once each piece was glued together, assemble the tool. First, grab the pole and put one end piece on, then apply each glued piece in any order you wish. Once the three glued pieces are slid onto the pole, cap it off with the second end piece. It's complete!

I provided clips of each piece, demonstrating their purpose in a simulation. Enjoy!
