Hand drill for drill bit with hex shank

I can work with that text. Hand Drill Made with Tinkercad, Copy Modify and Share. The hex shank size here is 6.5x7.5mm. If you need to modify this size, simply ungroup the design, change the polygon size, and adjust its height if needed for a deeper hole. After editing, select everything, align centers, and group it all again. After printing this tool, clean out any supports from the hole and chamfer the edges so the shank fits smoothly. The first time you use it, inserting the drill bit into a piece of wood will help get the shank inside the printed hand tool easily. Simply press it in, pull it back out many times until it slips in place effortlessly - you may need a tool to remove the shank at first.
