Ender 5 Extruder Arm with M4 bolts

thingiverse

I really admire IamSLy's vision with the original extruder arm, showcased here: https://www.thingiverse.com/thing:3595328. As someone who frequently rearranges things, I required a way to detach the extruder from the extruder arm without resorting to wood screws. I felt that relying on wood screws would inevitably damage the extruder arm upon removal, forcing me to reprint it if the screws couldn't be reinserted easily. To avoid this dilemma, I opted for M4 x 20mm hex cap bolts and M4 nuts to secure the extruder. I deliberately left the bolt slots running the full length of the arm to minimize infill usage, enabling me to utilize a longer bolt than 20mm if necessary. Using 20mm is essentially the minimum recommended size.
