The first PipBuck prototype (Based on Fallout 4’s Pipboy model) me and Penguinbrony24 came up with for our FanFiction called Fallout Equestria - Lightning Strikes Twice. (Link to Fanfiction)
 
After quite a bit of research on existing PipBuck models many artists came up with, we found out few of them had a fully developed and detailed exterior interface that all creatures could use, considering the size of their hooves/paws/claws/etc. and the lack of fingers (for Yaks, all 3 pony species and Zebras).
 
So we came up with the idea of a bracelet, that comes in multiple sizes, that attaches to any given species’ front leg of their choice, where their “wrist” would be.
 

 
PipBuck 3000 Spark X Bracelet features:  
-The interior of the bracelet is padded with the same material used for the PipBuck’s interior padding; making for a comfortable fit without getting loose.  
-The robust black silicone stylus allows for precise pushing and moving of the different buttons and switches found on the Pipbuck 3000 Spark X and other previous models.  
-The clasp uses snapping buttons that are fixed by holding the mouth handle with the user’s teeth and pushing onto the corresponding slots on the bracelet.  
-To release the clasp, the clasp’s switch must be pressed with the user’s free hoof or muzzle. This will unlock the snapping buttons.  
-!!!CAUTION!!! DO NOT USE THE MOUTH HANDLE TO FORCE RELEASE THE CLASP BY PULLING. THIS CAN DAMAGE ITS MECHANISM.  
-!!!CAUTION!!! Although the stylus is made from high quality silicone, it is not medical grade quality. Please refrain from introducing it in your body or another creature’s body. Stable-Tec is not responsible for consequences related to the misuse of the product.
