Sometimes when you're looking for a writing instrument, it's hard to find it if you have several pencils in it. This design can be used to insert a pencil or knife brush that is used frequently. Inspired by the gas can for use in a jeep. You can print at once without support. Lids must be printed separately. If you like it a lot or make a pre-purchase, I can officially sell it at FAB365. I ask for your participation.
