I have modified westenskow's original Clank! Insert (https://www.thingiverse.com/thing:3498817) to allow me to fit all of the existing expansions (Temple of the Ape Lords, Gold & Silk, Mummy's Curse, & Sunken Treasures.) Here is what I did:
I made all the walls and floors thinner (1mm thick instead of 2mm, this saves material and allowed me to gain more volume for chits and pieces.
I shortened the trays to accomidate an additional map
I changed the width of the gold tray 'pockets' to give more space to the Ones since there was so much less space available

I also changed out the Player Box with one from Zigma's Clank! Legacy insert (https://www.thingiverse.com/thing:4246651) as it was more easy to modify to be thinner (to accomidate the additional map).

Lastly I modfied a 'Market Holder' from Zigma's Clank! Legacy insert (https://www.thingiverse.com/thing:4246651) to hold 6 market items in stacks, and a spacer below to help keep them flush and not spill out..

All together I am able to fit all the exampsion into the box

With the newly thinned walls, westenskow's 'map access' can now be used to hold the bag as well as provide map access.

Please excuse my poor prints of the player tray and setup tray! I was trying to have just a honeycomb infill bottom but didn;t realize that having no top layer mean the curved surfaces were going to suffer! If I had more PLA to re-print, I would ;)
