Spinn-E Grabber - FTC Part Intake

Update - 

• Added updated Grips to provide better contact with the cone, making it easier to pick up the cone.
• Added 2x 10mm M3 Bolt and 2x M3 Hex Nut to connect the Turny Grip v3 B to Turny Grip v3 A to better hook in the cone.
• Connecting bolt holes for Turny Grip v3 B are 16mm apart, thus enabling them to work with standard Tetrix Max beams for replacement parts or prototyping.

Description - This is a grabber designed to pick up the cone element from this year's FTC challenge. It is designed to be able to pick the cone up from almost any orientation and lift it up easily. This is modeled to use a 180 servo, or 360 if you want 360 degree rotation.  It is also modeled to be able to swap out the grips to be able to pick up other objects, I haven't modeled any other grips, but the dimensions are available. Enjoy!

Print Tips - 

• All parts come in the best print orientation.
• Many of the parts will not need support, and I recommend not putting any supports in bolt holes because they are harder to remove and generally not needed.
• For the Base, you do not need any supports except for the connection to the Servo Bearing Bracket.
• For the Spinny Bit, put supports on everything but the square hole that connects to Servo Connector A (if your printer can bridge well enough) and all the horizontal bolt holes around it. Have caution removing supports from the servo holder, it is thin and fragile.
• For the Turny Bit, it is recommended to rotate it 45 degrees to the bottom layer of the overhang has a shorter distance to travel, making it straight. (Shown Below)
• No other parts should require supports.
• Based on your print bed, a brim or shirt should be fine, but use a raft if needed.
• These are printed in PETG, but PLA should work as well, though use finer layer heights, thicker walls, and more infill if needed. 
• I would highly recommend putting higher infill on both Servo Connector A and Servo Connector B because they have a lot of force on them, so you want them to be strong.
