designed this for my uncles DND (dungeons and dragons) group.
features:
 

• Place for a Pen or pencil, allowing for sizing up to carpenters pencils since that is what he uses mostly.
• 100x75x28mm (not including the free space in the lid) area for storage of character mini figures.
• Dice storage for up to 9 dice.
• mounting for 4 2x2mm recessed magnets (not needed but its there.)
• area for the tray to sit underneath if not in use.

yes i know that there are other models out there but this is the one i created from scratch, i do have the original .F3d files as well.
i personally do not play DND so if there are any issues leave a comment and i will try to revise the design in my free time.

this design is to large to fit on a A1 mini  as the dimensions are 126x200x29.36mm.

for those that use imperial system. 4 61/64 x 7 7/8 x 5 5/32
