This is a Rolling Tray with a Storage Box for Papers where RAWs should fit in perfectly and a Hole with a diameter of 5.5cm for a Grinder.
Other Features include a slideable V Stand for Rolling and a small hole with a 6mm diameter for holding a tip in Place so it wont get bigger.

Note: 
The version on the pictures is my protype which had 1mm to less for my grinder to fit and the V-Stand was a little to short in that version which is now fixed, I just didnt print it yet because I dont want to waste all my filament. :)
Also I would recommend to print with ironing and maybe Do the layheight on smooth, that worked out well for me.
