MK7 Spring Compressed Extruder - Heavy Duty
thingiverse
I was tired of trying to get different extruders to work that were small and minimal in size. I was having too much issue with flexing and breaking parts. So I designed a heavy duty MK7 Extruder. Based off the exturder I found here (http://www.thingiverse.com/thing:245677) Instructions Uses a MK7 Drive gear, a single 608ZZ bearing, 2 compression springs (.30" OD x 1.25" long), a M4 nut, 4 M3x25mm screws and 3x M3x5MM Screws Printed .3mm layers ABS or PLA Print all at one time to keep uniform sizes -MK7 drive gear -608ZZ Bearing Compression springs (.300" OD x 1.25" long) M4 nut 4x M3 x 25mm screws -3x M3 x 5mm screws
