From the video's description, “This should give all the instructions needed as well as an indication of what you can do to make it all your own - best of luck and I hope it helps.”

In this video, the process of preparing the graphene–(presumably) glycerine suspension for mixing into the plastic is explained.

In addition to its hardness, the conductivity (of approx. 2.5Ω/cm) is also demonstrated.

Also, how this might be adapted to that papier-maché / 3D-printed moulding process (more generally, but also in the context of producing the joinery for the bike):

Casein–Fabric Reinforced Sheeting

Can the technique presented in NightHawkInLight (2022) be modified to use Casein instead of the Silicone–Nafta mix to produce translucent, semi-stiff sheeting?

Silicone-Impregnated Fabric

NightHawkInLight. 2022. Recycled Bedsheets Make The Best Waterproof Tarps. Video. Retrieved from

In this video, a method of creating strong, water-proof tarpaulins using fabric and a silicone–naphtha solution is presented.

Specifically, a volumetric ratio of 1 part dry 'compressed' fabric to 0.75 parts naphtha to 0.15 parts 100% silicone sealant was used. The silicone-naphtha solution is prepared in advance, with the mixture being lightly agitated in a tough plastic bag until it achieves the consistency of a light maple syrup; the fabric to be treated is then placed in the bag too, let to sit until it absorbs as much of the solution as it can, and then kneaded to try and achieve an even distribution. (Any spots that weren't suitably impregnated can be placed, face-to-face, with a well-treated area and wrung together afterwards.) Finally, the impregnated fabric is hung to dry / cure for approx. 24 hours.

As an aside, it is also mentioned that, when waterproofing backpacks, etc., using this technique, a 1:1 mix of silicone and naphtha should be used and applied to the item using a brush instead.
