Have you ever wonder how you could make something fun out of your failed prints. Have you ever wanted to make a custom hacky sack. How about using failed prints as filler for your hack sack. This is what this design is all about.

Items needed:
Hand sewing needle or sewing machine
Upostary thread*
Materal
Failed prints
Scissors
Needle nose pliers
Sheet of paper
3D printed pattern
Pen or marker
Something to break down the prints

• You have to use this kind of thread. Normal thread will fail quickly

First print the pattern at 0.20 layer height. Next trace the pattern twice on the material and cut them both out. You'll be sewing this inside out. Start with the pieces in a T shape as seen in the photo #1. Thread your needle and tie a double knot at the end. Sew along the edge about 1/4 or 6mm in from the edge. The tighter your stitches the more round it will be in the end. Continue to sew until you have around a half an inch (12mm) left open (photo #2). Don't cut the thread yet. Use the pliers or pen to assist in turning the material right side out.

Now you'll need to handle the breakdown of failed prints next. Do so however you can. You want the size of the bits to be equal to a small bean. You'll need about 1 cup (or 226g) of filler for the hacky. The exact amount depends on how full you want it. I'd recommend at least 3/4 full. Now roll the sheet of paper in to a funnel. Make the end able to insert into the hole left over from sewing. Pour in the filler to desired amount. I'd suggest doing this over a trash can or container since it's usually messy.

Now you need to finish up sewing. The stitch this time is different then before. You'll use a blind or ladder stitch (Watch the video below to see how to do it ¥¥) so the stitches don't show. Once you've closed the hole, back up a stitch and push the thread back under the last stitch. Then cut the thread so you can tie a double knot. Try to get it as close to the surface as possible. Then tuck it in if needed. That's it, you're done.

You can use any fabric that will hold the stitch well. Cotton, polyester, nylon, and suede leather. If you use leather you will want to use needle nose pliers to push the needle through while sewing.

÷÷ Elaborate patterns for hacky sacks
***Update: I uploaded 3D printable patterns for the elaborate hacky sack patterns. To know how to sew them together visit the site below.

The only thing to know about doing these more complex patterns are they have more seams and therefore more failure points. Be sure to sew through the corners for tighter seal.
