+# Standalone Knob Tensioners
+
+This mod is designed to provide a simple and sturdy solution for tensioning belts on the Ender 5 Plus(Need confirmation for the Ender 5) Mercury 1 and Mercury 1.1 Systems
+
+<img src="https://github.com/Vprince099/UserMods/blob/70ca9a4ffd59bd3d6dac79b1b4dd776309475bd6/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Showcase_Image.PNG" width="50%" height="50%">
+
+## Description
+
+This Mod is derived from the enclosure project I am currently working on (Jan-2023). In order to provide a version that can be used by the entire Mercury community. I have forked the design and will upload the enclosure version once I am done. This was inspired by the Voron V0. This provides a sturdy solution for tensioning your belt while maintaining a design that allows clearance for an enclosure.  
+
+## Dependencies
+
+* **Please print in ABS or ASA**
+* Due to the tight clearances of a part like this, I recommend this part be printed on a properly calibrated printer
+* I **Do not** recommend scaling the parts via a slicer as you may have issues with fitment
+
+## Bill of Materials
+Item Name | Quantity | Notes
+| :--- | :---: | :---
+M5x12mm BHCS | 2 | Needed for Rear Mount
+M5x25mm BHCS | 2 | Needed for Inside Mount
+M3x6MM BHCS | 8 | Needed to secure lid
+M3x4mmx5mm Heatset Inserts | 8 | Needed to secure lid
+M5 T-Nut | 6 | You should have at least 4 existing T-nuts from the Original BOM
+M5x20mm SHCS | 2 | From Original BOM
+M5x30mm PIN | 2 | From Original BOM
+M5x1mm Shim | 4 | From Original BOM
+F695 Bearing | 4 | From Original BOM
+
+## Installation
+
+### Step 1 - Install Heatset Inserts
+
+* Install the Heatset inserts with a soldering iron for both the Left and Right Frame printed parts
+* Total amount of Heatsets to install is **8**
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Heatset%20installation.PNG" width="50%" height="50%">
+
+### Step 2 - Mount Frame to Extrusions
+
+* Install the T-Nuts on both sides of the extrusion frame
+* Total amount of T-Nuts to install is **6**
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/T_Nut_Intsallation.PNG" width="50%" height="50%">
+
+* Install the M5x12mm BHCS at the Rear Mount hole
+* Install the M5x25mm BHCS at the Inside Mount hole (This is a longer bolt to provide more structural rigidity)
+* Repeat these steps on the other side as well
+* Total amounts 
+   * M5x12mm BHCS quantity of **2**
+   * M5x25mm BHCS quantity of **2**
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Securing_frame.PNG" width="50%" height="50%">
+
+### Step 3 - Install Bearing Stack
+
+* Install the bearing stack as prescribed in the original instructions for the Mercury Printers
+* At this time you should insert the M5x20mm SHCS since the bolt will be held captive once the tensioner is inserted to the frame
+* Repeat this process on both sides
+* Total amounts 
+   * M5x20mm SHCS quantity of **2**
+   * M5x30mm PIN quantity of **2**
+   * M5x1mm Shim quantity of **4**
+   * F695 Bearing quantity of **4**
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Installing%20BearingStack.PNG" width="50%" height="50%">
+
+### Step 4 - Install Belt
+
+* If this is a new build, follow the steps prescribed in the original instructions for the Mercury Printers
+* if this is a retrofit, you will need to install as pictured below
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Alternate%20Installation%20method%20for%20Bearing%20Stack.PNG" width="50%" height="50%">
+
+### Step 5 - Install Tensioner
+
+* Slide in the tensioner to the frame
+* Attach the M5x20mm SHCS to the T-Nut but **Do Not** fully tighten
+* **Note** - the M5x20mm SHCS may catch on the initial hole
+   * The Stadium Shaped Slot can be used to lift the bolt
+   * This slot also exists in case you need to uninstall the tensioner - *since it will be captive once fully inserted*
+   * A pick and hook can be used for this or a small screwdriver
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Install_Tensioner.PNG" width="50%" height="50%">
+
+### Step 6 - Install Knob
+
+* Install the knob but **Do Not** fully tighten until everything is installed 
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Install_Knob.PNG" width="50%" height="50%">
+
+### Step 7 - Install Lids
+
+* Install the lids on the sides of the frame
+* Use the M3x6MM BHCS screws to secure the lids
+* Total amount of M3x6MM BHCS screws to install is **8**
+<img src="https://github.com/Vprince099/UserMods/blob/9484fb143167ddbe990767eebb4dfe4484cb84fe/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Install_plate.PNG" width="50%" height="50%">
+
+## How to use
+
+* Tension using the Knob
+    * Ensure you are tensioning equally on both sides i.e 1/8th turn on each side simultaneously
+<img src="https://github.com/Vprince099/UserMods/blob/f209a1665c24bf2940ba4b4ddfbcd25a18824565/Mercury_One/Vengeful/Standalone_Knob_Tensioners/images/Tension_Process.PNG" width="100%" height="100%">
+
+* Lock using the internal bolt inside the Stadium Shaped Slot
