These grip shells for the Gecko are printed in wood PLA.
They show the two new Rainbow Mods & Props special designs: RMP HEX & RMP FULLHEX
However they are available in all Gecko grip designs. So please see the last picture for all available grip designs and choose one you like.
These can be ordered separately or added to a custom Gecko build.
The great thing about wood PLA is that it give the texture and feel of sanded wood. Speaking of sanding, this filament can be sanded and stained just like normal wood. So if you want to change the look of your grip you can just do it that way.
I also show the wood grip in this Gecko upgrade video.
