X-Axis belt tensioner for geared GT2 pulley

thingiverse

The original design has been working flawlessly for several months now. However, upon receiving my new 16-tooth GT2 pulleys, I had to disassemble it only to discover that they wouldn't fit into the original tensioner. To resolve this issue, I opted to retain most of the thin parts and redesigned the body. The result is a longer design with a wider guiding hole, allowing users to install cheap pulleys by simply removing the side guide plates (refer to the accompanying picture). The improvement in print quality along the x-axis is nothing short of astonishing. Enjoy! I designed this X-axis belt tensioner to provide single-handed quick adjustment of the x-axis belt while maintaining the 'stock' bearing block. The pins on the body exert axial pressure on the x-axis shafts, rather than the Z-axis bearing block. This innovative design consists of three parts and can be printed in approximately two hours. To assemble this device, you will need: One M4 x 16mm Hex bolt and corresponding nut. One 1/4" x 13/32" spring; any spring that clears the M4 bolts OD and the wheels ID without being too long will suffice. I reused the stock belt bearing, nut, and bolt.
