Mini Table Saw v3 - Four Gears

Mini Hand Powered Table Saw v3 - Four Gears This is the Four Geared version of my Mini Hand Powered Table Saw, featuring a gear ratio that spins faster than its predecessors at about 1:3. For every turn of the crank you make, the blade will rotate three turns, making it an improvement over the first two versions. With four gears instead of just two, I didn't need to have one gear sticking through the top like in the previous version. The two extra gears are mounted between a special arch and one of the sides of the table, giving it a cleaner look by removing all outside washers where the cranks went through the sides. Like the previous two versions, everything was printed without supports except for the Crank assembly and the Top. My Monoprice Select Mini printer even managed to print the Table Bottom without supports, though just barely, with some layers curling under before it could bridge the gap and close the tops of the largest openings. The half circle opening in the Crank is particularly difficult to clean out, so I added a drop of glue to keep it on the Crank shaft otherwise it would fall off after rigorous cranking. When attempting to cut something, hold the Table firmly in place with a small clamp or a second pair of helpful hands. Check out the video to see it in action at https://youtu.be/9sZSOpMYHnE.
