After getting tired that all plastic scrapers are done after one use I finally decided to use metal scraper that came with the machine. however I did not particularly like the design of the original scraper BambuLab provides on microSD card/website - see model <a target="_blank" href="https://wiki.bambulab.com/en/knowledge-sharing/Links-to-STL-models" rel="nofollow noopener">here</a>.&nbsp;I decided to model my own which was inspired by Wera tools I love. It is nice design which fits really well into your hand.&nbsp;UPDATE (2024-03-08)As requested by some I made a <a target="_blank" href="https://makerworld.com/en/models/237518#profileId-253541" rel="nofollow noopener">stand</a> that fits my design… &nbsp;UPDATE V2 (2024-02-03)Based on the feedback from community here and some more though into the design I modeled V2 of the scraper.Also you can find info at the bottom how to use it to avoid damage to your plates.<ul><li>Improved geometry at the bottom</li><li>Tweaked dimensions of finger rest and added indented arrow to prevent wrong orientation</li><li>Added logo to both sides (AMS version only)</li><li>Increased layers for logo for AMS version (to prevent color bleed)</li><li>Lowered indent for magnet so it protrudes just tiny bit (stronger magnet force)</li></ul><figure class="image image_resized" style="width:29.94%;"><img src="https://makerworld.bblmw.com/makerworld/draft/662366/2024-02-03_d4a9546ae3269.jpg"><figcaption>Improved design + indented arrow</figcaption></figure>And there is one more thing… I also created honeycomb ultralight and hopefully very cool and stylish version! <a target="_blank" href="https://makerworld.com/en/models/169754" rel="nofollow noopener">check it out!</a>&nbsp;FEATURES<ul><li>Cool Wera design</li><li>Easy to print an assemble (no more confusing where does the part go from the original model…)</li><li>No supports, flawless print</li><li>Hole so you can hang it if you wish</li><li>Dedicated space for the magnet</li></ul>&nbsp;WHAT DO YOU NEED?Well nothing! You should have everything already when you purchased your printer.<ul><li>18g of material (PLA is just fine)</li><li>2x screws for scraper</li><li>Blade</li><li>1x magnet (optional)</li></ul>HOW TO USE IT?As the original model also this one can be used from both side, but it shouldn't! I was thinking about poko yoke solution, but that would hinder its functionally so here is an example how to use it. On top of that I added arrow to the part where fingers rest to make it more obvious.&nbsp;<figure class="image image_resized" style="width:65.31%;"><img src="https://makerworld.bblmw.com/makerworld/draft/662366/2024-02-03_b4d2d3df686c2.jpg"></figure>I would not recommend using this scraper of textured plates and would be very very cautions on smooth PEI to. I think it is ideal for cool plate, but could not find any information from BambuLab regarding the use case, so that is only my opinion…&nbsp;&nbsp;&nbsp;&nbsp;

<h2>Bambu Color Blend Swatch</h2><h3>** Skip to the end for how to make custom swatches, and how to print. **</h3>----------------If you like my stuff, check out my patreon<a target="_blank" href="https://www.patreon.com/LilacRage" rel="nofollow noopener">https://www.patreon.com/LilacRage</a>-------&nbsp;The Bambu Lab AMS has revolutionized color 3D printing. Did you know you can print up to 5 colors from a single filament color, plus black and white? This variation in tint and shading is achieved by adjusting the number of layers of color filament used and changing the color of the filament that prints behind the adjusted color.&nbsp;&nbsp;&nbsp;&nbsp;<h3>Theory</h3>Note: For our purposes, and for the dictionary&#39;s purpose, TINT = color + white, and SHADE = color + black.&nbsp;&nbsp;In my testing, I&#39;ve found that at a 0.2mm layer height, most filaments are often translucent, allowing light to pass through easily—similar to how most 3D printed light boxes work. For speed, ease of use, and limiting color changes, I&#39;ve based these swatches on 3 layers of color. Taking blue filament as an example, three layers of solid blue filament provide a close approximation to the true tint/color of the filament. However, we can make it appear brighter by layering white filament behind it or darker by layering black filament behind it.&nbsp;<figure class="image image_resized" style="width: 41.3%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2023-11-18_7e1c8df519e45.jpeg"></figure>&nbsp;In this photo you can see two example color swatches and the various tints/shades achieved by layering different thickness of color behind them. All of the filament swatches are printed face down on the build plate and are set up as follows:&nbsp;<figure class="table"><table><tbody><tr><td>black</td><td>black</td><td>orange</td><td>white</td><td>white</td></tr><tr><td>black</td><td>orange</td><td>orange</td><td>orange</td><td>white</td></tr><tr><td>orange</td><td>orange</td><td>orange</td><td>orange</td><td>orange</td></tr></tbody></table></figure>(substitute orange for whatever color you&#39;d like to test)&nbsp;So, we&#39;ve got one layer of orange with black behind it, giving us a dark reddish-brown, pure orange in the middle, all the way to one layer of orange with white behind it, giving a nice light orange color.&nbsp;<h3>Practice</h3>Okay, this is neat, but what&#39;s the point? Well, you can achieve a lot more colors with a single AMS (or multiple AMS units) than you thought possible! In theory, each color will give you 5 distinct tints/shades. In our above example, we have 5 colors of orange and 5 colors of brown, plus black and white—giving us 12 distinct colors from 4 colors of filaments. However, we can also layer the black and white to give us silver/gray tones, potentially resulting in 14 distinct colors from only 4 original colors of filament.<figure class="image image_resized" style="width: 38.46%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2023-11-18_1e97ebc3019358.jpeg"></figure>There is no gray or silver used in this print. Only Black/White/Red/Brown.The silver and light gray are from layering black behind white.From the edge, we have black, single layer of white, and two layers of whiteall with black behind it.&nbsp;&nbsp;And one more example of a bit of ‘advanced’ color blending that I&#39;ve been working on:&nbsp;<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2023-11-18_fdb029a74e9078.png"></figure>I&#39;m not 100% happy with the colors I for the various parts,but you can see approximately 12 distinct colorsand the only filaments used were orange, brown, black, and white &nbsp;<h3>How to make custom swatches</h3>Using the Maker World Customizer:&nbsp;In order to have a separate STL file for each color, white, and black portion of the swatch you must export each piece of the swatch separately. To do so, select the tickbox for swatch_color, then download the swatch color. Then untick the swatch_color and tick swatch_white, then download the swatch_white file. Finally, untick the swatch_white and tick the swatch_black and download. Now that you have all 3 parts of the swatch downloaded you can drag all three relevant STLs (black, white, and color) into Bambu Studio at the same time. Bambu Studio will ask you if you want to load these files as a single object with multiple parts. Select YES.&nbsp;<img class="image_resized" style="width: 28.78%" src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2024-05-24_e3c118cbb37598.png">&nbsp;&nbsp;USING OPENSCAD:I have provided the SCAD file for the swatches, which are parametric. This means you can enter your filament information and create custom swatches for your favorite brands and colors.&nbsp;Requirements:You will need a copy of OpenSCAD on your computer. OpenSCAD is a free and open source CAD modeling software.<a target="_blank" href="https://openscad.org/" rel="nofollow noopener">You can download OpenSCAD here</a>&nbsp;Once you have OpenSCAD installed on your machine, open the ‘Bambu_Color_Swatch.scad’ file.The left side contains all the programming for the swatches. Unless you are familiar with OpenSCAD, DO NOT EDIT THE LEFT SIDE.The right side has all the parameters, which ARE editable for you to make your own custom filament swatches.&nbsp;<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2023-11-18_af6c3090042f9.png"></figure>&nbsp;From here you can choose the size of your swatches, which part of the swatch you want to render and export, whether you want to include a text box or not, and the information contained in that text.&nbsp;If you are not choosing custom sized swatches, you only need to export the ‘swatch color’ portion of the model, which contains the text. Do so by unchecking the ‘swatch white’ and ‘swatch black’ checkboxes. Then render (F6) and export (F7) the file to a location on your computer. If you are using a custom-size swatch, you will need to export each part—black, white, &amp; color—of the model separately.&nbsp;<h2>How to Print Your Color Blending Swatch</h2>Drag all three relevant STLs (black, white, and color) into Bambu Studio at the same time. Bambu Studio will ask you if you want to load these files as a single object with multiple parts. Select YES.&nbsp;Now, the filament swatch is in the slicer, but it is all one color by default. You must select each object individually in the side panel and set the appropriate colors—black for black, white for white, and whatever color you want your swatch to be.&nbsp;<figure class="image image_resized" style="width: 41.67%"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000067884/design/2023-11-18_b3b998e20f633.png"></figure>Here we are printing a red color swatch.The Black STL is set to black filamentThe White STL is set to white filamentThe Color STL is set to RED Now you can slice and print your color swatches!
