Remix made from scratch in Fusion of an already brilliant design by AMT_MW with some small improvements: Much more robust attachment point for lanyard or keyring Adjusted knurling for improved grip Adjusted tolerances Adapted to affordable bit set from AliExpress Changed outer design (from the original thermos flask shape to more sleek tampon shape :D ) Slightly narrower and longer bit head to reach bit deeper located screws Check out more of my designs and hit follow so you won't miss any upcoming functional models! I aim to upload at least one original, practical model every week. Stay tuned! 😊
