Remixed design to support 15 frags and extended the hangars to sit lower in the tank, as well as multiple spots to move the rack up and down to accommodate light acclimation. Uses minimal filament.
Print 2 hangars. Use the "HangarAdjustable" file to have multiple mounting heights.
Print @ 100% for 1 inch frags, or 125% for 1.25 inch frags. If scaling up remember to print the hangars at the same % to ensure the mounting works properly.
Print in PETG or ABS
