It seems like you're detailing a redesign of a 3D printed belt drive feeder for a 1.75mm filament printer, specifically addressing issues with the original design's performance and functionality. Here are some key points from your description: ### Key Improvements * The redesign focuses on improving the performance by modifying the files to accommodate M5 x 45mm Hex "Part Threaded" bolts. * A bigger hole for the M5 bolt in the longer "Pin," a bigger groove for the M5 bolt in the "Push Plate," and a larger Hex Hole for the M5 bolt head are included. * The redesign also includes a Nut Grip for 12mm Bowden Tube Clamp 4mm tube. ### Print Settings * Printer: Protomaker Black Sprint Original. * Notes: Setting as stated in Cura images attached. ### Design Considerations * A specific note is provided about the "Push Plate" holes, where one side should be drilled to 4mm and the other to 3.5mm for the 4mm bolt's movement and tightness. * TinkerCad was used as the design tool, with inspiration from the Belt Feed MXL Belt Bowden Extruder 1.75mm on Thingiverse and the Dragon Symbol from MyMiniFactory. ### Files * The following files are included: * `20_tooth_MXL_Motor_pulley.stl` * `USE_Hex_Bolt_Main_Body.stl` * `USE_Pins.stl` * `USE_Push_Plate_no_nut_needed.stl` * `USE_Thiner_Main_Belt_Drive.stl` ### Caution * The 20-tooth belt pinion is recommended to be printed in aluminum due to potential slippage issues with the plastic model.
