Articulated Snake

Model of a snake, consisting many articulated segments.

Each segment can move and rotate.

There are four versions.

• Taper has a tapering body. The segment just behind the head is 24mm wide, which grows to 34mm at the widest point, then tapers down to 13mm at the tail.
• Small has segments of constant width. Each segment (excluding the head) is 16mm wide.
• Short is almost identical to Small, it just has fewer segments.
• Big has segments of constant width. Each segment (excluding the head) is 33mm wide. You can print as many segments as you want.

Big segments have a larger range of motion than small segments.

Number of segments includes head and tail.

This model was inspired by Friendly Articulated Slug by Copper Keep.

Print Instructions

Taper, Small, and Short are Print-In-Place.

On Big, the segments are printed separately.

Print the test first! There are texts for the print-in-place versions ("snake-taper test", “snake-small test”). The test consists of only 4 segments. It allows you to test your printer setting and practise breaking the segments free.

Printed at 0.2mm layer height.

No supports.

Use a brim for “snake-big segment”.

After Printing

This applies only to the Print-In-Place versions.

This will take a lot of work.

Every hinge will have to be handled seperately.

1. Take a small knife and insert it one third of the way into the gap between two segments. Start at the side or top and move it all the way around.
2. Move the segment side-to-side to break it free.
   • Do not try breaking it free by rotating. Doing so will only break the stopper which keeps the segments chained together.

[UPDATE 2024-10-14] Made the hinges on taper stronger

[UPDATE 2024-10-16] The Big versions is no longer print-in-place. Turns out printing the segments separately and putting them together later is not only possible, but also a lot easier.
