These corrected drive sprockets are specifically designed for the Trumpeter 1/16 M1A1 and M1A2 Abrams (models 00926, 00927) kits. The original parts in the Trumpeter kits are significantly undersized with an incorrect pitch, leading to a poor fit with the kit's track when assembled. This often results in the tracks looking unsightly over the sprocket, a well-known issue with these kits. There are also two types of sprocket teeth available for Trumpeter kits and Heng Long gearbox (refer to the photos for reference).

The file includes a one-piece drive sprocket and a sprocket cover. All you need to do is place the sprocket alongside Trumpeter's details and then fit the sprocket cap over it once assembled. The sprocket is designed to fit perfectly with Trumpeter's track links and final drives. After assembly, the sprocket wheel remains operational, ensuring that the track links stay workable.

All details come pre-supported; you simply need to open the file in a slicer and print it.

We also offer variants of the sprockets for Tamiya 1/16 kits (models 36212, 56041). Additionally, there is an option for a sprocket designed for the Heng Long gearbox, useful if you wish to motorize the Trumpeter kit.

Recommended for MSLA (Resin) 3D printers, this model has been successfully tested with the Elegoo Saturn 3 Ultra. The best results are achieved with a layer height of 0.22-0.25 mm and anti aliasing ON.
