<h2>Summary</h2>These are devices for fixing sandpaper, which are suitable for manual grinding and for machine grinding. Clamping and tensioning of the sandpaper is performed by rotating the inner cylinder with a slot with an 8 mm hex key. The end of the sandpaper strip is inserted into the slot of the inner cylinder. The beginning of the tape is attached in the slot on the base. If your sandpaper is paper-based and the grit index is high, it will be too thin. Then it makes sense to cut off longer and for better fastening fold it in half in those areas where the tape is attached in the slots.Two models are made for manual grinding. In the form of a drop with a width of 40 mm, for fine grinding and for grinding in hard-to-reach places. In the form of a bar with a width of 80 mm, for grinding large open surfaces. If desired, the width of the models can be easily changed by simply pulling on the Z axis, in any 3D editor. Machine grinding can be done with a drill and with the help of angle grinder. The grinding drum for the drill is available in two versions. With a diameter of 40mm and 70mm. To assemble the grinding drum for the drill, you will need a hex head bolt M6x50mm, which will serve as the drum shaft for mounting in the chuck. And the M6 nut for fixing the bolt. The length of the bolt can be chosen differently, depending on your preferences. To assemble the grinding drum for the angle grinder, you will only need the M14 nut. Perhaps your angle grinder has a different thread, then you will need to modify a model or write to me. &nbsp;ATTENTION For the sanding drum on the angle grinder, in view of the high speed, use only cloth-based sanding paper.<a target="_blank" href="https://youtu.be/BtptNuI0F4Q" rel="nofollow noopener">https://youtu.be/BtptNuI0F4Q</a> <h3>Parts links below:</h3><ul><li><a target="_blank" href="https://s.click.aliexpress.com/e/_97Doip" rel="nofollow noopener">Sanding Abrasive Paper</a></li><li><a target="_blank" href="https://s.click.aliexpress.com/e/_AOXF0h" rel="nofollow noopener">M6x50mm DIN 933 Hex Head Bolt</a></li><li><a target="_blank" href="https://s.click.aliexpress.com/e/_EynLIRB" rel="nofollow noopener">M6 Hex Nut</a></li><li><a target="_blank" href="https://s.click.aliexpress.com/e/_EynLIRB" rel="nofollow noopener">M14 Hex Nut</a></li></ul>

Update August 22, 2023&nbsp;Rollers updated to version 1.3, offering slightly increased tolerances against the roller slots. Thanks to @AdamL for the feedback!&nbsp;Update August 5, 2023&nbsp;The rollers were redesigned and updated to version 1.2. I've found in testing that tapering them from larger diameter in the edges to smaller in the middle will do a better job of forcing and keeping the spools centered than the old design. There are still three sizes, the largest one (16.5 mm) is similar in size to the stock roller while the others are smaller to allow for larger diameter spools.It might be a good idea picking up some extra 693-ZZ bearings (link in the BOM below) and have a set of each so you can quickly switch rollers for normal and smaller spools.&nbsp;AboutThis is a set of improved rear rollers developed for Hydra AMS. It will also work with the standard Bambu Lab AMS but I've only tested it briefly. The diameter of the roller is around 2 mm less than the stock rollers, allowing larger diameter spools without having to use a lid spacer. It's also slightly wider than the stock roller. There are also other sizes available depening on your requirement, see more belowAnother improvement is that the roller bearings are moved from sitting outside the roller on a thin 3 mm plastic pin to being installed in the actual printed roller with an M3 socket head screw for strength.<blockquote>With the current Hydra AMS (1.08) and the standard rear rollers, the maximum diameter of the spools with the lid closed is around 202.5 mm. With these improved rear rollers you can use up to around 203.5 mm spools with the lid closed.</blockquote>Be aware that smaller 1 Kg spools than standard, say 190 mm diameter, will rub against the bottom of the Hydra AMS if you use the rear-most position of the rollers. For these you can either use one of the larger rollers or use the adjustable socket head casings in the raised position:<ul><li>socket-head-casing-adjustable-1.3.3mf</li></ul>BOM - Bill of Materials&nbsp;You can print the parts in just about any filament you like. You need some M3 hex socket heads (around 25 mm is fine, shorter or longer will also work). I usually recommend this kit which I've had for years and use for most of my designs and builds.<ul><li><a target="_blank" href="https://s.click.aliexpress.com/e/_9julXz" rel="nofollow noopener">440 pcs M3 Hex Socket Head Cap Kit</a></li></ul>If you do not want to reuse the stock roller bearings or want a spare set / different sized rollers, you can buy some extra bearings:<ul><li><a target="_blank" href="https://s.click.aliexpress.com/e/_EzRwOoX" rel="nofollow noopener">693-ZZ bearings</a></li></ul>Which should I print?&nbsp;The stock rear rollers have a diameter of around 16.10 mm near the edges. Depending on if you want to raise or lower the spools, print the appropriate roller:&nbsp;Example A) You have a large diameter spool (202 mm). Using the standard rear roller it rubs against the roof of the AMS. Use a smaller rear roller (try 13.5 mm or 14.5 mm).Example B) You have a small diameter spool (190 mm). Using the standard rear roller it rubs against the bottom of the AMS. User a larger rear roller (try 16.5 mm or 17.0 mm).&nbsp;Print Settings&nbsp;Print the parts in the direction I have set them, no supports are required. Use random seam. Print a set of one rear roller and two socket head casings for each roller you want to replace:<ul><li>rear-roller-for-hydra-ams-14.5mm-1.3.3mf</li><li>socket-head-casing-1.3.3mf</li></ul><blockquote>If you use a stock Bambu Lab AMS or an earlier version of Hydra AMS (1.06 or earlier), print this instead: rear-roller-for-bambu-ams-14.5mm-1.3.3mf</blockquote>How To Use&nbsp;First, carefully remove the bearings from the stock rear roller. You can use pliers to pull them off:<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_7x1hiwmqs1oc.jpg"></figure>Next, press in the bearing into the printed part, one on each side:<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_zpyxsmj8ba8f.jpg"></figure><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_v61ch00ub8qz.jpg"></figure>Next, slide in the M3 socket head into the casing and the roller:<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_q86pbwgprhtt.jpg"></figure><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_l0e7acdicgav.jpg"></figure>Now you can install it in the AMS:<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_ilw57b7nx7o6.jpg"></figure>If you need to remove a bearing from the roller you can use a 2.5 mm hex tool, insert it then put a little pressure by twisting to grab the center ring then pull straight out:<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/user/466667527/draft/2023-09-18_1qdooogikrb3.jpg"></figure>

<a target="_blank" href="https://www.printables.com/de/model/418290-sanding-wedge-v2" rel="nofollow noopener">Printables Link</a>&nbsp;General informationAs you might have guessed from the title, this is the 2nd version of my sanding wedge. I made the models in Autodesk Inventor. &nbsp;The new design is Fully 3d printed, no bolts or nuts needed.&nbsp;Technical detailsThis sanding wedge is made for 50mm wide sandpaper. The sandpaper must be at least 310mm long for the original version and 225mm for the small version.I recommend you buy a roll of Sandpaper that already has the desired width and then cut it to length.&nbsp;Here are some I found on Amazon: <ul><li><a target="_blank" href="https://amzn.eu/d/5q3raSU" rel="nofollow noopener">Bosch DIY Sanding Roll for Metal 50mm 5m 120 Grit </a></li><li><a target="_blank" href="https://amzn.eu/d/gXm8hH8" rel="nofollow noopener">Klingspor 4224 - KL 361 JF Sanding Rolls with Fabric Backing, Brown, 50 x 25000, Packaging Unit 1 - Grain 180</a> </li></ul>&nbsp;Update 11.10.2023 : I added a brim and spread it over more plates to reduce printing errors. Also made the hole in the "wedge" bigger because it was too tight.
