2040 extruded aluminium

thingiverse

This is a versatile 2020 and 2040 aluminum extrusion system designed to offer enhanced strength through the strategic placement of a steel rod within its center hole, which measures an impressive 0.25 inches in diameter. This setup enables users to construct a hypercube corexy printer or other types of printers with confidence, provided that the design incorporates reinforcement to ensure stability and durability. Notably, for individuals utilizing this system to create bed slingers of the i3 type, it is crucial to limit the bed size to 250x250x250 dimensions. Exceeding this threshold may result in the system's inability to handle the increasing mass of the bed, potentially leading to structural instability or even collapse. On a more positive note, when using this aluminum extrusion system for core xy printing setups, it is likely capable of handling larger bed sizes without issue. However, it is essential to exercise caution and consider the specific design requirements to ensure optimal performance. In terms of width, it's worth noting that the 20x20x200 ext alm and 20x20 ext al small aluminum extrusions feature a consistent 5mm V-slot width, whereas the other 20x20 and 2040 extrusions boast a slightly wider 6.25mm V-slot width.
