In case this is still of interest (oh, pun intended ; )
In 2020, the people at SolidFX still have them DR800 cases listed in their website, and I made (and will probably make again) my own cases for my DR1000s. I only
took pictures of the first prototype back then (you'll find the SolidFX link there as well), but I could upload pics of the final model (rather worn out by now ; )
