RFID Clips for Bambu Spools with embedded chip

The original model

Why a remix?

This remix is a complete recreation of the model since I was unable to work on the original STL file, so I've created it using AutoDesk Fusion 360 since it's the only 3D modelling software I'm currently able to work with.

I wanted the RFID chip to be embedded inside the clip itself so I created a hole that is covered.

To be noted

This model is designed to be printed only with layer height 0.20mm or 0.10mm, other settings may cause undesired effects.

The model uses Pause at Height feature, which means at a certain point the user will have to do certain actions (read below).

The hole

The texts located in the A section are placed using the Bambu Studio text tool and are 0.50mm in depth, this will cause text to extend to 3 layers when printing at 0.20mm and 6 layers at 0.10mm. Extending texts more in deep will cause the hole to be partially filled with unwanted material.

The hole is 0.60mm in depth which is enough to put the RFID chip with it's original sticker and optionally (Beware: do it at your own risk!) a drop of glue.

The above layer is 0.50mm height but when printing this with 0.20mm layers height, it will result in a 0.60mm space. This does not alter how the model works when attached to the spool.

Inserting the RFID chip

While printing the printer will create the hole for the RFID chip to be placed in, when the top of the hole is reached, the printer will enter do pause, the hot end will move apart and you will be able to apply the RFID chip inside the hole.

When the pause is reached, you will receive a notification.

When placing the RFID chip please make sure it somehow sticks to the bottom of the hole.

If the sticker is not sticky anymore, you can consider using a drop of glue, but be aware that you need to make sure glue doesn't contact with the hot end nor the plate or you will damage the printer/plate. Proceed at your own risk.

After placing the RFID chip, press on the “Resume” button and the printer will heat up again (if temperature has dropped) and then start printing again with a layer covering the hole and sealing the chip itself.

Changing layer height to 0.10mm for higher quality

If you want to achieve a better print quality with smoother curves you can consider setting layer height to 0.10mm. Please be aware that doing so, the printer will have to print twice the layers and this will increase the printing time to up twice the time.

To check if you're working with 0.20mm layer height, in the left sidebar, follow these instructions.

1. Check to be on the Global settings;
2. Check to be on the Quality tab;
3. Check that values for both Layer height and Initial layer height are set to 0.2 mm.

To switch to 0.10mm change both values to 0.1 mm.

To revert to previous value use the circle arrow button near the input field.

Updating the Pause at Layer command

Changing the layer height to 0.10mm will cause the pause being at a wrong layer.

To check, set or edit Pause at Layer settings, follow there instructions.

1. Make sure you're in Preview mode;
2. Make sure you have sliced the plate with the lastest settings by clicking the Slice plate button.

A scrollbar indicating the layers will appear on the right side of the window.

Click with the primary mouse button on the plus icon on the top of the scrollbar and keep the mouse button pressed, then move down until you reach the layer where the pause is set.

Once the pause layer is reached, release the mouse button.

As you can see the small circle on the right side becomes an X (delete) button, press it to delete the Pause at Layer command. After removing the command you will need to slice the plate again by pressing the Slice plate button on top of the window.

Now scroll between layers and find the last layer where the hole is visible and uncovered.

After adding the pause command you will need to slice the plate again by pressing the Slice plate button on top of the window.

Pause should be at these layers reflecting layers height.

Changing texts

You can personalize the three texts on the bottom side of the clip by settings texts.

Before continuing rotate the view to be able to see the texts from the bottom of the plate, then follow these instructions.

1. Make sure you're in Prepare mode;
2. Make sure you're in Objects settings;

3. Select the text object you want to change and click with the secondary mouse button on it, there are three lines:

   Line	Font size	Description
   1	Big	Material
   2	Big	Type
   3	Small	Brand

4. Select the Edit Text menu item from the popup menu that appears.

Note: there are by default two clips on the plate because every Bambu Lab spool comes with two chips, so you have to repeat this procedure for both objects.

Bambu Studio will enter text editing tool and automatically show you the editor.

1. Enter the text you want to be shown in the Input text field;
2. (optionally) you can choose to change settings of your text like, Font, Size and making it Bold by pressing the B button;
3. (optionally) you can raise or lower spacing between characters by setting the Text Gap slider;
4. (optionally) you can move the text by dragging with the mouse the indicator on the surface;
5. Exit the text editing tool by pressing the return button.

You can repeat the process for the other texts.

Please be aware that small fonts or small interspaces between letters will cause quality issues or unreadable text.

Don't change the other parameters at least if you don't know what you're doing.

Changing filaments

You can personalize filaments of each of the texts as well of the clip itself just by following these steps.

1. Make sure you're in Prepare mode;

2. If you din't already sync with your printer/AMS the available filaments, print on the Synchronize filament list from AMS icon;
    

3. Make sure you're in Objects settings;
4. Select the object you want to change the filamento to from the list and click the rectangle containing the filament index;
5. Select the new filament from the popup that appears.

Alternatively, once you selected the object, you can just press the corresponding number on your keyboard to set the filament index.
