ANET A4 Carriage, Belt Tensioner and Tower Endcap Remixes

thingiverse

These remixes are specifically tailored for the ANET A4 delta printer, all designed within TinkerCad. There are four unique tower configurations included: Optical Endstop, Closed Pulley, and Extended for Belt Tensioner Remix; Optical Endstop, Closed Pulley, and Original Belt Tensioner; Original Endstop, Closed Pulley, and Extended for Belt Tensioner Remix; Original Endstop, Closed Pulley, and Original Belt Tensioner. The tower endcaps are based on a design by Nicky00, designed to be printed without any additional supports needed. They work well with GT2 16-toothed pulleys, as well as the factory split pulleys. In some models, I've spaced the pulley out more to better align the belt to an alternate belt tensioner. A pulley offset has also been added to space the pulleys away from the walls. Both optical and standard endstop versions are included. You will need to snap off the built-in pulley offset support once cooled off. If you have trouble fitting it over the 8mm rods, install all the original screws and nuts first, then boil some water, drop it for 20 seconds, and press it on the rods while warm. The belt-tensioner remix uses a 30mmx4mm bolt, two - four 2mm nuts, and one 4mm washer (one of the nuts is pushed into the thumb-wheel). It was modified from a version by Drorness but redesigned to work with an ANET A4. Install the mounting screw first (not all the way through), then tighten the belt, and mount it to the carriage slide. The carriage remix removes the need for the little white plastic spacers for the diagonal rods while maintaining proper 50mm spacing of the effector rods. I included the original remix by Jinhyuk and added one redesigned for use with optical endstops. The hole for the tensioner goes on the left-hand side when installing the carriage on the rods (when looking at the rods from outside the printer). Remember that if you've cut your belts to fit just the factory tensioner, you might need to have longer belts on hand to go the extra distance in the loops. Factory GT2-6mm belts are pretty stiff and could use replacing anyway. The location for all versions can be found at https://www.tinkercad.com/things/iMYkJIuOWYR-anet-a4-carriage-remixes.
