When you have cut the edges according to the directions above, grab each flap and stretch the fabric over the corner of the wood piece. Then, cut parallel to the surface of the wood leaving about 1/4" to be folded later.Īnd then square off the tops leaving about 1/4" to be folded later on as well. Make a cut in the middle of the seam to make two distinct flaps. In order to get this fabric to lay flat you will need to: Now you will notice some excess fabric sticking up due to the stapling of the four edges. When doing this, be sure to pull as tight as possible so we get tight edges as opposed to loose/bubbled edges. I made some marks for you to see approximately where this needs to be. Next, place the wood square on top of the fabric located in the center. (The amount of fabric you cut out will depend on your waist size) *ALSO* If you are more of a visual learner (like I am) here is the video I used to learn how to do this.įirst, cut out around 12-20 squares of fabric at 3.5" wide x 3.8" long. *NOTE* If you would prefer to just spray paint the wood rather than cutting all of the fabric out, then you may skip this step all together and do that instead! With a little practice, you will get good at it! If you're thinking "I can't do that - I've never upholstered anything in my life!!" let me assure you I thought the same thing when I started this project. I love this project for a variety of reasons, but one of them is that this project incorporates so many skills from electronics and 3D printing, to sewing and upholstery techniques. Step 8: Wrapping the Wood in Fabric OR Spray Painting Wood I tried to avoid adhesives in this project to minimize the mess. *Note* If you don't have a sewing machine, you may use spray adhesive instead to join the two straps. This made the belt strap about 2.25" wide. I put the seam about 1/8" in from the edge on each side and trimmed off the excess so there would be a straight and clean edge. Then, with the two grayish/white interior colors facing each other, I sewed the pieces together. But, you could make it 35" for example, if it is just going to be you wearing it) (I made it much larger so that the belt could be adjustable for other people who also want to wear it. For example, my waist measured to be about 34", so I cut two strips fabric at 2.5" wide and 45" long. I thought this would look much better and a lot cleaner than simply painting the wood pieces.įirst, measure your waist and determine how much fabric you will need. Step 5: Circuit Diagram / Wiringįor this step, I went to my local fabric store and got some blue vinyl. With the two motors secured within the housing, it is time to wire the circuit together. If you only hear the hum of the motor shaft rotating then you have done it correctly. If you can hear an obnoxious rattling sound, than it is still too loose. In order to check if the motor is sufficiently secure, attach the leads of the motor to a battery. To make sure that the motors are secure within their designated housing, place a small piece of foam or rubber between the motor and the top of the housing as shown. The design has a little bit of tolerance so that the motors can be easily inserted and removed if something were to happen to them (for example, if they burn out or an electrical connection pops loose). The two motors will be used to simulate the tickling you see in the show. When the motor shaft rotates, the weighted end causes the motor to vibrate. These motors are no different than a normal DC motor with the exception of added weights to the end of the shaft. In order to create the tickling effect for the belt, I purchased 2 vibration DC motors. I accounted for tolerances in the initial design so it should be good to go! If it doesn't fit, check your printer settings/accuracy and try again. Once the pieces have been printed, it might be a good idea to check and see if the back half can screw on to the front (It is better to know this now than later). Remove the support material and sharp edges using some pliers and a piece of sand paper. Otherwise, you might spend a significant amount of time cleaning out the threads so that the two pieces will finally fit together. *Tip* When slicing the STL files, be sure to avoid adding supports to the threads. Fusion 360 has some excellent and easy-to-use features to implement 3D printed threads into your designs. Also, there are some threads added so that the back can be easily removed if there is an issue with the electronics, or if a battery needs to be replaced. It has a small cavity in the center to hold the motors and the electronics in place. My goal for this design is simplicity and functionality.
