Compact Bowden MK8 Remix

thingiverse

This is a redesigned version of the Compact Bowden Extruder, using an MK8 drive gear as part of its mechanical makeup.\nThe attachment method has been changed to enable the extruder's placement on a level 2020 aluminium extrusion, rather than another design.\nThe standard bearing in this redesign is an MR105 model, replacing the more commonly used 625 version, and a tapered thread feature for an 1/8" diameter R push-fit connector bore adds greater stability.\nThanks again for the provision of STEP files, these are highly valuable.\nYou will require the following components: NEMA17 stepper motor: 1 MK8 drive gear: 1 MR105 Bearing: 1 R1/8" push-fit connector: 1 608 bearing: 1 2 spring units with an internal diameter of at least 3mm M3x30mm, or M4 x length if longer needed for springs (you need two), screws and 2 extra to provide even more space (2x) spring spacers of different lengths Fasteners: 4x M3 screws: M3x8mm screws (you will need 4 of these) 1x long M3 screw (for use as guide rail attachment) and 2 spare. M4 screws - needed for fastening in position Print settings: Rafts:\n Off\n \n Support Material: On\n The object supports the material.\n Print at least two, you should also make the raft height very low and a good resolution Resolution: .20mm or as per need (to match object) - higher is faster to print Layer Infill Percentage 40
