Backpack Destroyman III

In this project I created a small figure of a creature from a game I occasionally play. It is designed to be able to be clipped onto backpack straps or any other area where something can be hanged off of. It decorates areas where things can be a little better.

Start with the creation of the main body. Create a sphere on the top plane. Start from the origin and type 40mm. Press enter.

Move sphere upwards 7.5 mm.

Select split body, and split the body along the top plane.

Select scale, then select the top half. Click non-uniform scale type, and scale the x-direction by 1.3. Click OK.

Then, scale the bottom half. Select non-uniform scale type, make the x-scale 1.3 and the z scale 0.56. Click OK.

Create 8 cylinders with a diameter of anywhere between 8-10 mm and a length between 13-15 mm.

Click draft, select the bottom face of one of the cylinders for the pull direction, click all of the curved faces of the cylinders, and make the draft angle 4 degrees. Click OK.

Select Shell, and make the inner width 1.5mm. Click OK.

Move the cylinders to the back of the main body. Angle them such that it appears that they are sticking out of the main body.

Offset the top plane by 16mm.

On that new plane, create a 3.5mm Diameter sphere. click ok. If you are dissatisfied with the placement, move it.

After finishing the position, mirror it across the Front plane. Click ok.

Offset the front plane by 27mm.

On the offset plane, create a conic curve. Then offset this curve by 0.5mm. Connect the 2 curves with a line at the ends. Emboss this feature onto the main body, and make the depth 0.5mm. Click OK.

Reactivate the offset plane. Create 2 equally sized triangles on the plane and click OK. Extrude these triangles by 0.3mm. Attach these triangles to the mouth by moving them into position.

Offset the top plane by -9.5mm. Select create sketch, and make 2 circles 8mm in diameter.

Extrude 1 circle by 20mm, and make a 10 degree taper angle. Select new body and click OK. Extrude the other circle by 20mm, make a 12.5 degree taper angle. Select new body and click OK.

Move the 10 degree taper circle 6mm down. Change the X-angle to -35 degrees. Change the y angle to -20 degrees. Move the angled cylinder such that a large portion of it is within the main body, and the tilted bottom face is not over the offset plane. Click OK. Then, select split body, select the leg, and choose the offset plane as the split plane. Click OK. Remove the bottom portion under the offset plane, and fillet the bottom part of the leg by 1.5mm. Click OK. Then, mirror it across the front face.

Move the 15 degree taper circle 6mm down. Change the x-angle to -25 degrees and y-angle to 20 degrees. Move the cylinder so a large portion is in the main body and the tilted bottom face is not over the offset plane. After, select split body on the leg, choose the offset plane as the split plane. Click OK. Remove the bottom portion under the offset plane, and fillet the bottom part of the leg by 1.5mm. Click OK. Then, mirror it across the front face.

The main body is completed. Combine all the parts.

To create the clip, we will make a carabiner attached to the top. Make the following sketch on the top plane.

Offset the right plane so that it reaches the carabiner. Create a sketch on this plane, and make an 4mm x 4mm rectangle on the carabiner. Sweep it along the carabiner.

Make the following sketch on the right inner side of the carabiner. Extrude the ring downwards by -2mm, then extrude the sketch downwards again by -0.5mm.

Chamfer the 2 bottom edges of the carabiner by 1mm. Do the following fillets.

Extrude cut the s shaped sketch and the three slots on the smaller end of the carabiner all the way through.

Move the carabiner such that the vertical center roughly is on the front plane. Create the following sketch on the front plane.

Create the following sketch. Then sweep it. Fillet the two side faces by .5mm. Use the move tool to create a copy of it, and rotate it by 90 degrees. Make sure the two parts are looped around each other but not touching. Then, create a third copy of the link and move it far enough such that it loops but does not touch the rotated copy. Add more links if you wish.

On the top plane, make a 10mm circle and offset it inwards by 1.5mm. Extrude the ring by a whole length of 3m. Filet the entire ring by .75mm.

Make the following sketch. Extrude it both sides symmetrically by a whole length of 3mm. Fillet the body by .749mm and move it such that the top hole is looped around the end of the chain that was created earlier.

Scale the carabiner, the chain, and the loop together. For my project, I scaled them by a factor of 2. You can also scale the Destroyman seperately. I scaled mine to 1.3. After you finish scaling, combine the loop to the top of the destroyman. Make sure it's center is aligned with the destroyman's center.

Scale the final body and carabiner as needed to adjust to your purposes. For me, I scaled my carabiner by 2.00 and the body by 1.40. Ensure that the bottom layers of the two bodies line up if you are printing them together.

Attach the Destroyman to the chain by squeezing in the ring to the chain.
