M4-thread Bed Mount for D-Bot Printer

thingiverse

This is a re-implementation of the D-bot printer's bed supports, strengthened and modified to utilize an M4 bolt and nut instead of M3, due to the stock springs failing to provide sufficient support with the heavy 300x300 aluminum bed (5+lbs including the silicone heat pad and associated hardware). Note: The bolt spacing has been increased by 1mm from the aluminum rail compared to the original design (6mm vs 5mm), as a result of the larger space required by the M4 nut. Consequently, these modifications are not an exact drop-in replacement; you will need to make slight adjustments to the bed's arms for the revised spacing.
