We currently make clear and colored diffusers for the following lights:
Wurkkos TS10, Emisar D4V2, Emisar D4SV2, Emisar D1V2, Emisar D18, Noctigon KR1, Noctigon KR4, Convoy S2+, Convoy T3
We also make battery holders! They are very durable.
Single battery holders: AA/14500, 18350, 18650, 21700
These single battery holders double as a diffuser if you get the adapter.

I ran over an 18650 snap holder with my truck to test the durability. It survived!
Some frequently asked questions:
Q: Will the diffusers melt?
A: Our diffusers are made from PETG which is more heat resistant than the typical PLA used in 3D printing. I have personally never melted a diffuser even when on full turbo. Thermal step-down usually occurs before the diffuser gets warm. I once made a black diffuser to test heat resistance and I was unable to melt it. All this being said, your light may be different so we take no responsibility for melted diffusers.
Q: Are the battery holders waterproof? Why don’t you add an O-ring?
A: Sealing using an O-ring requires a surface finish that is smoother than we can reliably achieve using FDM 3D printing. We do not want to provide a false sense of confidence in the degree of water resistance to these battery holders, so we did not implement O-rings into the design. Secondly, it would increase the cost and these are already a very low margin product.
Q: Some of your battery holders are made of carbon fiber. Isn’t carbon fiber conductive?
A: We have tested this carbon fiber using a multimeter and it is non-conductive. The fill % of carbon fibers is too low to create a continuous conducting pathway.
