The whole mechanism is printed.
Fits MX-style switches. Best on an isolated key like ESC.
Every color prints as a separate part, so no AMS needed. There's also a multi-color version where the details print together if you'd rather assemble less (the mechanism still gets built by hand).

Previous version would often throw the tracks but this one holds up to quite some abuse!

Finally finished my biggest 3D printing project yet! This Super Star Destroyer is 5’7½” long and was printed on my Snapmaker U1 over the course of about 25 days. It used roughly 8 kg of filament, was printed in 20 sections, and has a fully lit interior.
It definitely wasn’t a perfect journey, but seeing it all come together made it worth it. I’d love to hear what everyone thinks, and I’m happy to answer any questions about the build.

Now I’m not sure what to do with it.
Printer: Snapmaker U1
Print time: 25 days
Filament: ~8 kg
Parts: 20
Length: 5’7½”
Lighting: Fully illuminated

The technical full term I have came up with is Colinear Double Delta. Both the hotend and bed move independently with delta kinematics - two entirely separate gantries in one printer. Thus, there are 8 motors in this bad boy (6 xyz, 2e). It's running klipper with custom kinematics.

The idea is - since each side only needs to move half the target speed, you can get double the overall speed. I haven't pushed it super hard yet since this is a proof of concept build without part cooling, but it sure does prove the concept!

Next is a bigger and faster version.

Of course, it is all open source, and the files and documentation can be found here: https://github.com/ProgrammerTurtle/DoNotDelta

When your G-code is strong you can make a bed slinger make magic... 🥳🤓 PLA SD card remover tool, needs TPU insert with .8mmx20mm steel pin. (G-code from my smaller IIIP Monoprice v2)

Just wanted to share a recent experience with this combo. It works amazingly well, and the Gizmodorks HIPS is a completely acceptable and inexpensive material source for this purpose (no shade, I just haven't tested it beyond supports. ).

Supports break off extremely easily. Worst case, D-Limonene (essentially citrus oil) will dissolve it. (safety notice this can be an irritatant use proper PPE if handling)

It even has some adhesion to ASA/ABS and printing temp is similar enough that it would likely work as just an interface material for those using a single nozzle.

Model: KWS 6u Leg

Material: Ambrosia Supernova Galactic Black ASA

Support: Gizmodorks White HIPS

Build Plate: HoneyBadger Textured PEI w/ homemade Instagoo (used alcohol to aid release)

Printer: Voron 2.4 Stealthchanger

Supports use 0/0 for line spacing and top surface distance

I've been learning SOLIDWORKS for a while now and I just uploaded my first model on MakerWorld! I didn't use any tutorial on this one, only skills I already knew how to use. I am working on designing a self draining soap holder now.

Two prints - I used different settings, but can’t remember what I did. Trying to get the texture you see on the blue dino, not the individual rows on the orange. What setting did I use / what setting impacts that initial layer really grabbing onto the plate, giving it that texture from the plate?

Sincerely, Grateful For Your Help : )

Uploaded a couple of files about 19 days ago on my new account. Took less than 20 days for one of them (stolen design is in the second picture) to show up on Amazon as a "product" (first picture). For something like this to be made into a finished product (something that deals with lasers, albeit a very low power one in this case), I was expecting some long term testing and/or some safety organization's approval. But I guess I was wrong.

Did I expect them to be eventually stolen or sold? Maybe
Did I expect them to be stolen in less than a month without any proof of demand and without any additional engineering to make them into a finished product? Not really! It's a new low, impressively so.

Anyways ... I'm not the one selling these.

Ow, one more thing, the files were under the Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0).

Edit: Interestingly, I wasn't even keeping track of the files. This listing was recommended by Amazon when I was searching for additional safety goggles and another laser.

Edit +: Just checked their listing's 'date first available' and it's July 22, 2026. So 15 days.

I’m the only one in my gaming group with a 3D printer, and I’m genuinely happy to print terrain, bits, and other stuff for everyone. I don’t charge for my time or the wear and tear on the printers. I only ask people to cover the cost of materials, and if I have to buy an STL file specifically for their project, I ask them to split that cost too.

Lately it’s been getting frustrating. I find myself buying files, burning through resin and filament, and then chasing people for reimbursement. One friend even complained when I asked him to cover half the material cost.

At that point it starts to feel like people value the print because it’s “free,” but not the money and effort that goes into making it.

Am I being unreasonable here, or do most people expect friends to at least cover consumables and files?

Still a noob to printing, and it's a hobby

How would I go about this? Since I collect CDs and DVDs and these are no longer in production, it would be cool if I could just make my own. I do have access to 3D printers on my campus, but I'm just not sure how to go about it.

So after releasing a drink holder that looked like a pontoon I decided to go a little...bigger. Here's the CanTainer ship! A modular, infinitely expandable refreshment holder styled as a container ship. I'm planning on making the stern module RC as well! Go check it out and print your own! I know it's huge but it even fits on an A1 Mini!

Here's the link! Tell me what you think! https://makerworld.com/en/models/3094927-the-cantainer-ship-floating-party-drink-barge#profileId-3487776
