Tortoise straw flag holder

Having recently acquired a tortoise, I'm looking forward to letting him roam free in the garden. He's still very small and I was looking for a way to keep him visible, and read about people using flag type things to attach to their torts. I couldn't find a 3D printable solution, so quickly whipped this up. Please adjust the size of the elastic band depending on the size of your tortoise. The part that holds the straw is for a “standard” size drinking straw. For a more secure fit, a dab of hot glue before attaching the straw will make it more permanent. The band can be orientated two ways, depending how secure you'd like the fit. You can hook the band through the gaps, or as I have it in the pic.
