thingiverse

These parts enhance the superior mid T bot created by Bart Dring.\r\n\r\nVideo available here: https://www.youtube.com/watch?v=JLPwHxBBrQM\r\n\r\nFeatures:\r\n\r\n1. Head Block is now positioned with a servo slightly back more, providing increased surface contact on the pivoting pen arm above.\r\n\r\n2. Head block "ears" that hold the timing belt have been strengthened and redesigned for higher Z-lift of the pen.\r\n\r\n3. Pivoting pen base becomes modular and magnetic to support interchangeable pens.\r\n\r\n4. Magnetic modular pen ring snaps in and out quickly and easily on your mid-t-bot.\r\n\r\n5. A channel has been created to route the servo wire up and away from the Y-Stop.\r\n\r\nPrint a pen-ring holder for each pen you plan to keep and install 6mm x 3mm magnets on both the receiver and each pen holder on Amazon.
