I’m a PreK special educator working with a kindergarten student, “E,” who has a rare form of muscular dystrophy called Pelizaeus-Merzbacher leukodystrophy (a genetic condition that affects the brain and spinal cord, leading to challenges with muscle control, coordination, and movement).

We’re hoping to create a combined Chromebook sleeve/keyguard/wedge for his device (model N20Q10) that would support greater independence and access to learning and communication. The idea includes:

• A wedge to angle the keyboard so he can better see the keys

• A keyguard to help isolate individual keys

• A protective sleeve with a keypad blocker to reduce unintended key presses due to uncontrolled movements

Our goal is simple but meaningful: give E more independence, improve his ability to communicate, and help him more fully access his education.

We do have access to a 3D printer, but we need help with designing and creating the model file. I’ll attach a visual to help illustrate what we’re envisioning.

If anyone is willing to collaborate or even point us in the right direction, we would be incredibly grateful. This could make a huge difference for a really special kid.

Thank you so much 💛

I'll wear them for a bit and report back on comfort, breathability, and everyday performance.
If anyone else has tried these, feel free to share your experience!

I know that Phil Macey https://www.youtube.com/watch?v=IBGGHZj7kNY and Julia Boch https://www.facebook.com/reel/1854332722184608 have tried them.

It is an upgrade kit for my AMS 2 Pro that came with my bamboo H2 C printer. It allows individual temperature settings for each of the four spool bays and is compatible with in-use conditions so you can print and dry with four different spools simultaneously! However, I am stymied at two different points in the assembly and product integration with my existing bamboo AMS.

The first issue, which is more of an annoyance than a showstopper, there are four new pedestal feet that mount to the underside of my existing AMS 2 Pro. There are supposed to be pre-existing mounting holes in the bottom of the unit to attach these feet onto. I sent in a service ticket to bamboo labs about the lack of mounting holes. They were surprisingly aloof and acted like they had never heard of the AMS two pro upgrade kit by EIBOS. Again,Not a big deal, but irritating.

The real showstopper is the internal integration of the upgrade kit into the main body of the AMS two pro. There are four rough, poorly machined clear acrylic baffles that mount in back of the filament guide entrance, call the filament pedestal. a black plastic bracket snaps into it from the front side of the filament pedestals.

This step has two flaws. The thin acrylic baffles which you would normally injection mold were shaped by machining. A large slot nearly bisects the acrylic baffle, and where the slot ends was left completely sharp, no attempt at a fillet or radius at the deep end of the slot. Acrylic is very brittle and so they created a stress concentration point that makes the part maybe 1/4 as strong as it would be if they had a radius at the bottom of the slot. one of the four parts broke exactly at that location, because both the acrylic baffle, and the black plastic shroud that attaches to it won't fit around the filament pedestal, as it's about 1 mm wider than the parts they supplied.

All in all I'm quite disappointed that I've had both of these issues coupled with cheap manufacturing and additionally I've not heard back from their customer service regarding the issues. It will be sent back tomorrow if I don't hear from them. I really wanted this system to work like the enthusiastic reviews that I read.

Has anybody else had assembly and integration issues like this?

After seeing all the fun DeathRacer competitions organized by @TheRealSamPrentice at RepRap festivals, I couldn’t hold back any longer — I had to get a kit myself! From BIQU Shop. This thread will follow my first impressions, build process, and testing, and who knows — maybe even participation at an upcoming event like SMRRF! 🤞

If you need to justify your 3D printing hobby at home, here’s a handy electricity cost calculator 😉 Spoiler: it doesn’t use as much power as you might think. For UK folks, it’s even more reasonable.

We will be getting more handy tools to fill our Interactive Tools & Calculators category. Any requests? Do you have interesting examples of 3D printing costs? Share them here.

AI generators made a noticeable leap last year, and in 2026, this trend will continue with further optimization and wider adoption. What is especially interesting is how quickly chat-based AI tools are starting to generate simple, printable 3D models. While still basic, these tools are already lowering the barrier to entry, and in 2026 we will see more users actively relying on AI not just for ideas, but for producing usable starting points for 3D printing.

Another trend that will clearly carry over into 2026 is the success of tool-changer systems in the personal and prosumer 3D printing segment. What proved itself in 2025 will not be ignored by the wider market. More brands are expected to introduce their own versions, as the benefits are difficult to overlook: significant material waste reduction, faster multi-material workflows.

Finally, toward the end of 2025, we saw increasing investor confidence and substantial funding flowing into Chinese personal 3D printing companies. While 2026 may still be too early to judge the full impact, it is reasonable to expect the first results of this investment. It can be seen as faster product iteration, tighter hardware-software integration, or more aggressive market expansion.

Recently, I had the opportunity to review the K2 Plus Combo and was impressed with its features. Now, almost a year later, Creality has launched the K2 and K2 Pro. Interesting. The heated chamber and high-temperature printing capabilities will benefit printing with engineering-grade materials such as CF blends. Happy to test it for a detailed evaluation and to add more content to our existing guides.

Update: Although I could not test many engineering-grade materials yet, I did test the two-CFS setup — meaning 8- and 6-color printing. Here is the full review and print examples:
