Adjustable Extruder Drive Block Upgrade for Replicator 2X Free 3D print model

cgtrader

The primary goal of this innovative design is to provide a user-friendly mechanism for adjusting the pressure applied to the filament by the idler ball bearing. This creative solution draws inspiration from existing ideas, specifically Thingiverse.com's thing:136589 and thing:52203. Note that this adjustable extruder block is not intended as a direct replacement for MakerBot's original extruder block. Designed with power-users in mind, this advanced device allows users to fine-tune filament pressure and provides an alternative gripping mechanism. Please exercise caution when attempting to replace the original block, as it requires disassembling the current extruder and addressing any issues. For successful implementation, save the original parts and carefully follow the provided instructions. Access these step-by-step guidelines at bit.ly/1eaYi3p. Key features of this design include: - All components are 3D printed. - Stepless filament grip pressure adjustment. - Built-in filament dust filter with sponge (thing:52203). - Protective cover for stepper motor cables and connectors. - Reusable fasteners and ball bearing from the original extruder block. - A sturdy design that ensures durability. To assemble this adjustable extruder block, gather the necessary parts, including: - Base left (3D-printed part). - Base right (3D-printed part). - Lever left (3D-printed part). - Lever right (3D-printed part). - Bearing cover left (3D-printed part). - Bearing cover right (3D-printed part). - Stepper motor cable cover (3D-printed part). - Two M3 Nylock nuts. - Four M3 countersunk screws: two of 23 mm length and two of 6 mm length. - Two M3 hexagon screws, each 35 mm in length. The tools required for assembly are: - A 2 mm hex key. - Water pump pliers. - Beak pliers. - A few drops of super glue. Version History ---------------- This adjustable extruder block design draws inspiration from existing ideas, such as the Adjustable Drive Block Upgrade for Replicator 2 and 1 (thing:136589). This concept has evolved over time, incorporating elements from Spring-loaded Replicator 2 Drive Block (thing:53125), which itself is derived from three other previous designs. Information ------------ The MakerBot Replicator 2X Desktop 3D printer is designed for use with ABS plastic filament. It requires stable and temperature-regulated conditions, similar to PLA but in a more advanced form. For successful operation, the operator must be familiar with its capabilities and functions, including optimal temperatures and print speeds. A useful rule of thumb is to leave the top hood open only when larger 3D prints are made. Regulate temperature by adding or removing the hood in conjunction with opening or closing the front cover. The printer's temperature and air flow significantly impact its performance. The temperature around the extruder mechanism can reach up to 50°C to 60°C during 3D printing. For optimal results, 3D print the plastic parts of this adjustable extruder block in ABS (not PLA) with 100% infill for best strength and heat resistance. Keep in mind that this is an experimental design, and users must be prepared to adapt and troubleshoot. If used, learn from the experience.
