Bio
Engineer, Dr, airbrush artist. Novice designer learning Fusion360. Advanced woodworker and T-Strut designer. Some of my background is deeply connected with matters influencing the operation of a 3D printer - from thermal design to noise, vibration and conduction of energy in ways influencing print outcomes. I'm out of practice coding, and steadily learning how to do 3d design with CAD. I'm in Australia and love using my 3D printer to enhance my outcomes with speaker design, tool accessories and function and pretty much any functional problem where I can create a novel solution.

The profile is great - the design I would give a 4/5 because it has some weakness in a number of cases (pun intended :P). If you are using a horizontal install where the base of the rear support is locked in at the bottom, this will bend badly due to the "L" bracket being so thin and weak. What I did was glue a standard slot cover to the back of it - see my pic. A few dobs of superglue and its metal reinforced and good to go. I'm grateful for the design - it saved me making my own when I needed a simple method to mount 2 SSD in my NAS case (Lian-Li PC-25, it's no longer made). I like the open design which allows cooling air around the drives.

There are many poop chutes, yet for those of us using the H2 series printers and high temp materials, the open poop chute is a problem. It leaks heat causing temp stability issues and it leaks toxic fumes - VOC's and particulates during prints, completely bypassing filtration. This is a large sealed container with vertical slot to lock in place and block those leaking effects; it does not interfere with spool holders or other accessories.

One of the only systems I have found that mounts a hygrometer correctly. Many either block the back where the sensor is, or have it vented into the desiccant which leads to a reading of that not the ambient air humidity. Also the gaps are tight enough to keep fractured spheres of desiccant in. The fit is excellent and accommodates the latest AMS2 pro revision (as at Dec 2025 - 4 ribs on side not 6). THe containers also fit nicely with the filament cutter which I will use until all of the "black Tape" filament is out of the system. These genuinely aid in printing and with them done in ABS I can dry my desiccant in my oven or dryer without emptying it out.

This is so well designed. Printed in ABS. I love the intention of the ribs to maintain structural form with the thin walls. I'd love to know how you design to flow in 3d... I'm stuck with very blocky designs for now! I use Fusion 360 and have much to learn about CAD which holds me back as an engineer with so many ideas and much experience. The ultimate barrier really! Your sealed box resolves one of the most patently flawed design decisions on the Bambu printers - the open chute for poop. No chamber is sealed. Convection forces volatile fumes out into a room. Installing this instantly removed the smell of ABS which has to also mean massive reduction in VOC and particulates. For this alone I thank you. My health thanks you. Any ducting I now install will be effective. Others have sealed options but none are of a reasonable size. The only downside I have with this is that I cannot remove it with the side spool holders on. A small issue really but it could be a bit fiddly.

Very well prepared for printing - the tabs and dividers are indicators of careful consideration not only in the design, but also the usage and assembly. I have assembled my ABS parts and need to wait on a 4th cutter however can already express my view that the design is working. I noticed that one of the locking nubs (see image) is printed as a ramp not a cylinder. It is present on all 4 printed parts and I am curious to know if this is intended or a slicing / design flaw? Regarding assembly, I have a suggestion on sequence - placing the cutting blade in before seating the pivot arm onto the main assembly is easier. Let the cutter hang into the slot and then clip the arm onto the main body. My ABS spools may be too 'fat' for this device to easily fit in the limited AMS space and I am looking at options for that. A riser for the AMS lid, HDPE tape on the cutter device to reduce friction with filament roll are 2 ideas.

This is a very solid desiccant holder and I would suggest too much for most filament storage. Its robust construction and screw retained top make it perfect for electronic storage or other humidity sensitive options. I printed in ABS which will allow me to keep it as a closed brick that I dry without emptying. I am printing many desiccant containers to examine which are most effective for my storage needs. This one is very nicely done and I classify as over-engineered for simple filament storage. The volume I think is suitable for 32L-50L storage containers I think. Thank you to the designer - a well considered part and I appreciated the thought of having 2 screw sizes to accommodate the accuracy of people's printers.

These are a high surface area desiccant tray using minimal filament. The honeycomb structure retains well and does not flex like strip patterns do which is where desiccant falls out. I have printed in ABS so I can leave desiccant in and recharge in oven without having to dump it out. This is a bendy and loose fitting design due to its minimalism hence 4 stars. The desiccant assists in rigidity by adding body so fill it to brim but don't overfill so it's bulging. I am going to make some clips for it this morning that will keep it locked together and strengthen it while keeping the minimalist benefits. I will try to work out how to add them to the page (new to makerworld). Thanks to the Designer :) P.S. I'm testing a range of desiccant holders and this one rates well for use in filament storage.

These are a nice simple item and fit well. I'm cautious about which openings I block as some seem to have ancillary roles of ventilation. I don't think that has been raised as a concern for this opening and I'm always happy to reduce opportunity for dust to intrude into lubricated machinery :). I've found a few of your designs to be helpful so far - thanks for the efforts in your designs.

I'm satisfied that this advances the model in the manner I suggested to include accommodating PTFE curvature in the sagittal plane, not only the coronal. The angles are effective for reduced resistance, and minimising length of PTFE. The additional volume is offered for cable storage and this allows both the 4 and 6 pin cables to be contained neatly. Note the position in my images. The AMS is able to tilt back on the mounts of the riser, and the lid may open - all without limitation or interference by the new speed mount. Well done and thanks for being open to collaboration.

Works great. I used hygrometers off Amazon.com.au. Ebay will have them locally cheaper than Amazon. They are the exact model identified and fit nicely in the container with the front flush to edge. I printed in ASA which means my containers will not be impacted by the drying process of the AMS2 when I use it for high temp materials.

What a wonderful model. I'm not sure I need it however it was a great way to start my P1s printing efforts.

I'm impressed with the design. It is simple, effective and does not create any vibration or other issues with my P1S function. Assembly was simple and I used Superglue and PLA. Printing ABS the riser does not seem impacted by the chamber heat... will observe that over time but I hope it will remain ok. I have the AMS2 Pro V2 with the 4 ribs and the mounting was a bit finicky. I used a remix of a remix suited for this riser and it seems ok.

Thanks for this model - I like that it is minimalist and effective. I am using the bambu anti-vibration feet on my P1s which made the bin sit too low. I produced some simple round feet which I hot glued on to raise it 8mm and it now fits perfectly. This seemed the best way to alter the height so the print could still done with no supports. You may choose to offer an alternate version with the ramp 8mm higher :).
