The Freenove Big Hexapod is a great robot kit, but fangs and claws have to be an improvement!

The mouth is an 8 x 16 I2C led matrix sourced directly from freenove (it is the one they use in their ant robot among others), order from [email protected]
There is something similar on the Otto DIY website https://www.ottodiy.com/store/products/led-16x8-ultra-bright-matrix (out of stock at time of writing)
I have also found the ‘OPEN-SMART 0.8" Inch 16x8 I2C LED Dot Matrix Display’ on aliexpress (https://www.aliexpress.com/item/1005004399231415.html) (note pin order is different)
The hexapod board has an I2C expansion port that can be used for this.
The 4 arm pieces have a recess for 18.2mm od X 8mm id X 2mm Teflon washers, mine came from ebay https://www.ebay.co.uk/itm/143254187442?var=442177733362
Claw control is via 6 micro servos, the hexapod has loads of spare capacity for extra servos.
I have uploaded one set of files for the arms and claws, you will need to print a second mirrored set
A couple of bolts secure the Claw mount to the existing hexapod body
The non-powered claw is held in place with an M4 nut and bolt.
You may prefer to mirror the head piece if the ‘neck’ mount for your hexapod's head is on the other side
