Toughbuilt StackTech Rolling Tool Box - Gridfinity Baseplate

I needed a Gridfinity baseplate for the bottom of my Toughbuilt StackTech Rolling Tool Box ([https://toughbuilt.com/product/tb-b1-b-70r](https://toughbuilt.com/product/tb-b1-b-70r)) and couldn't find one anywhere online, so I decided to design my own. I'm posting the model here in case it's helpful for anyone else trying to organize this specific box. 

Design Details 

The bottom of the StackTech rolling box has some irregular geometry, so I designed this baseplate with custom cutouts to navigate those areas. It gives you a 5x11 grid section in the main area and a 2x9 grid section at the top to try and maximize the usable space.

I went with a 21mm height for the grid. This provides enough clearance for the bottom of the toolbox while giving the baseplate enough strength to support the weight of multiple stacked bins.

Printing & Assembly 

Because of the size of the toolbox, the baseplate is split into 8 separate objects.  Some objects require supports.

• Plates: The print profile is arranged across 3 build plates for the Bambu Lab P2S (or printers with a similar 256x256mm bed).
• Material: Printed in PETG, as this is going to live in the back of my truck and needs to survive higher temps.

• Assembly: The pieces just sit flush next to each other in the bottom of the box. The whole setup is held together by friction and by bridging your Gridfinity bins across the seams of the baseplate sections.  There are also cutouts for magnets, if desired.
