+# Voron Switchwire feed slot with filament pass-through
+
+This mod is a replacement for the stock feed_slot.stl, it adds a OD 4mm reverse bowden passthrough hole. It also removes the need for VHB tape with two clamps that screw into heatset inserts.

+
+## Parts Required
+ * 2 BOM heatset inserts
+ * 2 M3x6 button or socket head
+
+## Printing
+- Standard Voron part settings were used but the infill was dropped down to 20%
+
+## Installation
+1. Install heatsets on the bottom side of the new filament slot
+2. Remove the old feed slot and VHB tape
+3. Install the new feed slot and use the two clamps and M3x6 screws to secure
+
+## Note
+I designed this orignally for a bowden tube pass-through but at high Z the tube was unmanagable but would love to see if anyone comes up with a solution for this.
