The Bepleb is a modification of The Pebble. Rather than a fully domed, or convex shape, the top of the Bepleb is concave, giving a great worry stone effect and a comfortable place for your thumb when fidgeting. Like The Pebble, the Bepleb is a haptic slider that uses embedded 6x3mm round magnets, and teflon rails for an easy and controllable haptic fidget. Under your control, it can slide quitely, or snap loudly. They are printed to order in whatever color you like. Look below for color options. The example shown was printed with "marble" type PLA, which is light gray with black specks.
Because the magnet spacing and teflon rails are the same for the Pebble, it's possible to mix and match Bepleb and Pebble halves. My favorite combination is half Pebble and half Bepleb in my two favorite colors. :)
The Bepleb is $20 USD. Shipping is included for customers in the USA, but can be shipped internationally at additional cost.
3D Printing material/color options. Most are PLA, which is suitable for most prints. When there are special needs for flexibility, structural strength, or resistance to high temperatures, other materials can be used, and colors will be more limited.
