FlashForge Creater/Pro spring loaded extruder block

thingiverse

Human: I'm currently attempting to print NinjaFlex, but my vanilla extruder block won't cooperate.\nThe extruder blocks I downloaded from Thingiverse weren't a fit due to the larger wheel on mine, so I designed my own.\nAs an enthusiastic 3D printing spring enthusiast, I decided to create one using minimal external parts.\nFor this, you will need: \n1 x Wheel \n1 x 5mm (or 7mm) M3 screw \n1 x 10mm copper pipe with 4mm outer and 3mm inner diameter \n1 x 20mm M3 screw \n1 x 7mm M3 screw less than 10mm in length including the head\nThis project serves as a proof of concept, and I'm still refining the spring's tension.\nThe printer used to create this is an FDM one using PLA filament; it should also work with ABS, though.\nIf printed with ABS, you might experience a slightly softer spring, so try inserting some paper between the holder and spring for adjustment.\nThe parts were initially printed at 100% infill for aesthetic purposes but realize now that 25% to 40% infill will suffice; the parts being shells doesn't require much internal structure.\nDue to inadequate cooling, support was needed for the base block's round hole, which prints more evenly.\nA good cooling system could possibly eliminate the need for supports.\nThe tail of the spring proves to be a tricky print as it may "pops off" at 60 degrees Celsius from the heatbed occasionally.\nFor best results, try printing the first layer with a slow speed (15 - 30mm/s) and higher temperature (215 - 220C), followed by normal speed/temperature for finishing (60mm/s + 190C).\nPasting kapton tape, gluestick, or hair spray can be an alternative.\nThe model prints well directly on glass due to aesthetic reasons; it looks good!\nA layer height of 0.1mm should provide the most precision possible, though 0.2mm will also work.
