+# RapidoTZ Hotend Construction Guide
+
+This guide details the steps to build the RapidoTZ hotend, a modified Bambu Lab TZ 2.0 hotend with an extended melt zone using a Volcano nozzle and copper nuts, effectively transforming it into a Rapido V2.0-like hotend.
+Facing [layer adhesion problems](https://youtu.be/PPyiACzsLWM?si=C5Oih0QtXfa8OBcW&t=306) and flow rate drop-off.
+* The hotend costs about €12 in total.
+* 1 hour to build the hotend mod.

+
+## Materials Needed
+
+* Bambu Lab TZ 2.0 Hotend with Heater and Thermistor ([Aliexpress](https://de.aliexpress.com/w/wholesale-TZ-hotend.html))
+* Additional 40-50W Heater (Bambu Lab compatible, [Aliexpress](https://de.aliexpress.com/w/wholesale-bambulab-heater-50W.html), Sum: 100W to 120W heating )
+* Volcano Nozzle
+* Two M6 Copper Nuts (alternative Steel Nuts, thx to [CNC Kitchen](https://www.youtube.com/watch?v=_Soz8z-vAIw))
+* High Temperature Silicone (up to 450°C, e.g., [TFC-Troll-Factory-Silikon-Kautschuk-Typ-3](https://trollfactory.de/Produkte/Silikon-Kautschuk/Verarbeitungszeit/sehr-schnell-5-Min/TFC4021/TFC-Troll-Factory-Silikon-Kautschuk-Typ-3-HB-Zinnguss-hitzebestaendig-RTV-1-1-Groesse-1kg-2x500g))
+* Two M3 Screws (6mm length for Silicon Sock Mold)
+* Syringe 20 ml
+* [PETG Printed Silicone Sock Mold](https://github.com/LernFabrik/RapidoTZ-Hotend-Mod/tree/main/stl)
+* [Voron Stealthburner Bambu Printhead Volcano Mod](https://github.com/LernFabrik/RapidoTZ-Hotend-Mod/tree/main/stl): Hotend Front
+* [Voron Stealthburner Bambu Printhead](https://www.printables.com/model/322091-voron-stealthburner-printhead-for-bambu-x1cx1-hote): Hotend Insert, Back 
+
+## Tools
+
+* Silicone Sock Mold (3D printed, PETG)
+* File
+* Cutter Knife
+* Vise (optional)
+* Two Small Pliers
+* Thin Screwdriver
+* Allen Key for M3 Screws
+* Multimeter
+
+## Construction Steps
+
+1.  **Silicone Sock Mold Assembly:**
+    * Assemble the inner and outer mold parts using the M3 screws.
+    * Secure the lid, ensuring the inner part stays in place and doesn't rotate.
+    * Mix the silicone, fill the syringe, and inject it into the mold.
+    * Allow the silicone to cure completely.
+
+2.  **Hotend Preparation:**
+    * Secure the TZ 2.0 hotend in a vise.
+    * File the side opposite the original heater plate to create a flat surface for the second heater.
+
+3.  **Heater/Sensor Clip Modification:**
+    * Carefully bend open the existing heater and temperature sensor clip at the open end, creating a U shape.
+    * Carefully bend the U shape to a O shape, by bending the small Stegs of the clip.
+
+4.  **Hotend Assembly:**
+    * Assemble the hotend with the heater plates positioned opposite each other and the temperature sensor in between.
+
+5.  **Silicone Sock Removal:**
+    * Remove all screws and the lid from the silicone mold.
+    * Use an Allen key to push out the inner mold from below.
+    * Carefully detach the silicone sock from the mold edges using a screwdriver or Allen key.
+
+6.  **Silicone Sock Modification:**
+    * Cut a 5x5mm opening on the top of the silicone sock for the wires.
+    * Cut the sides of the sock, so that the sock can slide over the heatbreak.
+
+7.  **Silicone Sock Installation:**
+    * Carefully slide the silicone sock over the assembled hotend.
+    * Ensure the clip does not slide upwards, which could cause a short circuit.
+
+8.  **Electrical and Mechanical Installation:**
+    * Connect the two heater plates in parallel.
+    * Install the modified hotend into the printer's toolhead.
+    * Use a multimeter to check for short circuits in all wiring.
+
+9.  **Klipper Configuration:**
+    * Configure Klipper settings, including Z-probe offset.
+    * Remember to adjust the Z-probe position.
+    * Perform a PID tune of the hotend.
+    * Enjoy printing!
