This is my version of Hexagonal CItadel Clolors Holder, you can print them in PLA, PETG or even TPU.I suggest to print them with 0.4 Nozzle and 0.4 Wall ThicknessI will soon upgrade a version with 8 slots so you can alternate them and place the one near to the other an form a linear row of colors.EDIT: Added 8 Slots Version
