    I am working on it. I have improved the design and worked on new materials. I will post news soon.

    That's interesting . I'm curious as to what process and material you are going to use in making this ?

    Initially I wanted to use the laser sintered nylon12 like available there

    but I am not sure if the material properties are good enough to withstand the forces and heat caused by shooting. In addition the material is white and therefore will always needs to be dyed or painted.
    Right now I think it would be better to use another material with carbon particles, the material properties seem to be better when it comes to withstanding forces and heat, because of the carbon the colour is grey. The downside is that this material is expensive, with a total of 10 I still need to collect around 40$ more from every one, exact pricing will depend on the final design.
    I am working on testing both materials to see which performs better and if a material switch is needed for shootable grips.

    Hey Guys,
    after a longer period of little to no progress I can announce that I will switch the material to resin.
    The advantages are the hardness and the improved performance under heat, the hardness is said to be higher than that of the stantard constructionsite helmets here in germany.
    The disadvantage would be that the resolution is a little low, tolerances seem to be ok to tight. The lower resolution results in a more textured surface which makes it less slippery.

    The best thing is I can reduce the price for all to 130$ + shipping. The base color is now orange. Black or custom colors are no problem as long as the grip is for display only if you would need heatwidthstanding paint I will see if I can get them duracoated here, but I have no idea how much that will be.

    I will post pics today or tomorrow.

    Edit:

    When I was at the Gray Room Tour I had the opportunity to see the Prototype life and in full color ( although with most of the time with the lights out, since Iwas not too long in the training room). I identified some inaccuracies I built in without knowing. I do not think that these "mistakes" will affect the usability in a negative way therefore I will not change the current design. The current design will even allow you to sand down the texture to achive a form that is more close to the original if you do not like the texture or if you want a more close replica.

    First pics in comparison to a FDM printed sample:
