make tool box out of pipe for any size

thingiverse

Cut a piece of electrical pipe to the desired length, then fabricate the lid and base to match. To do this, use a 1.5-inch diameter pipe as an example. Next, heat up the lid until it's pliable enough to slip over the pipe, and apply adhesive to secure the base in place. Finally, adjust the model's dimensions to accommodate any pipe size you prefer.
