Readi-board (foam board) Dividers
thingiverse
I bought some cheap readi-board from the dollar store to make dividers in a drawer at home. I whipped these up to hold the board in place and they worked great. You'll just have to modify the Z height in the slicer to get your desired length. Original model at thangs.com: https://social.thangs.com/m/685425
