BondTech Mini Extruder with dual PC4-M10, dual Embedded Collet, or Single Slip

thingiverse

If you're looking to add bowden fittings to both ends of your mini extruder, you've got two options to consider. You can opt for the 10mm PC4 fitting on one end or go with the standard setup that matches the E3D push-in metal collars typically used by the mini extruder. Alternatively, there's a version without a top fitting and featuring a single PTFE slip cavity at the bottom. However, this particular configuration is only practical if you're running your extruder in direct drive mode and have already inserted the hotend's PTFE into the extruder for use as a filament guide.
