Grow a backbone and add this wearable spine to your costume! 

These vertebrae are derived from anatomically correct vertebrae and can be glued or sewn on to fabric.  Positioning templates are included to ensure accurate placement. See here for video: https://youtu.be/a72-hiMMajU

This project includes all lumbar and thoracic vertebrae of an adult male. When laid flat, the full length of the spine is 48.5cm. To modify the size, you may choose to leave out some of the vertebrae or scale the files as needed. Be sure to apply the same scaling factor to all vertebrae and positioning templates.

The placement template allows vertebrae to be laid out flat during assembly, however vertebrae have been designed to follow the natural curves of your back when worn.

Every attempt has been made to maintain anatomical accuracy, however, in order to make the parts as durable as possible the spinal canal on each vertebrae has been filed in, and select facet joints and bony processes have been thickened. These changes have minimal affect on the visual appearance.

Fabric Selection

A thick fabric such as denim will hold the vertebrae in place and apart from one another. The thin cotton used in the instruction video is not ideal in that it allows the vertebrae to flop around too much. If you plan on wearing as a costume, the fabric should hug the curves of your back as much as possible.

Printing

Select the vertebrae that you need and import them into your slicer. You will need to apply supports to the bony parts that stick out the back and to the sides. IMPORTANT: Be sure to label the vertebrae as they come off the printer! Vertebrae are labeled “L” for lumber (lower back) and “T” for thoracic (upper back.) Numbers start at the top and count down: T1 to T12 followed by L1 to L5.

Placement Templates

Determine the orientation of the three placement templates and position the top of “Template 3” just under the middle of the collar. Place “Template 2” and “Template 1” down the middle. It helps to tack the templates in place with a small dab of glue.

Attaching Vertebrae

Vertebrae are placed and attached from bottom to top. If you are using the spine for decoration or light use, you will likely be fine with just hot glue. Insert a sheet of plastic under the top surface so the glue doesn’t leak through to the next layer of fabric.  To make the spine more durable, use the holes provided to stitch each vertebra on to your fabric with strong thread, beading thread, or dental floss. You will need to remove the placement guides before stitching.

You are done!

Wearable Spine

Full spine for visualization only. Do not print this file!

These “Ghost Pop Beads” snap together to form spooky chains or rings as long as you want! Use for decoration or to accessorize your costume.

The pieces are designed to be printed in “Vase” or “Spiralized” mode. The file is optimized for printing with a 0.4mm nozzle. Printing with different nozzle sizes is still possible but will affect the tightness of fit.

Each piece uses approximately 0.4g of material, making this a great design to use up the scraps of filament you have lying around! A full 1kg roll could print approximately 2500 beads, enough to make a chain 50m (164ft) long!

To connect pieces together, simply pinch the bottom end of one piece to open it up. Insert the oval end of the second piece inside and release. The pieces remain connected but can be separated again if needed. Create long chains or rings by adding as many pieces as you want.

Each piece takes approximately 5 minutes to print. It is, however, much more efficient to print multiple pieces sequentially! Setting up spiralized models to print “one at a time” takes a bit of planning as the pieces must be spaced and sequenced properly so that the hot end or gantry does not collide with the finished prints as it moves on to the next print. 

Make the bottom open by setting “bottom layers” to zero. Good build plate adhesion is essential, so ensure that your machine is well calibrated.
