after doing some research online I found that that a common problem with these discoverers is that the little caps on the visors tend to fall off. I'm here to offer a solution. 

these are 3d printed with resin, and don't have the same ugly look that traditional 3d printing has, there are almost no layer lines and everything is very smooth.

Available in black. Other colours can be available but I cannot match the original colour as of right now.

made to resemble the original as close as my design skills allow me to make it! it's not a 1:1 copy but it's not far off either! 

any questions please ask :)
