It may seem super silly or I'm just somehow dumb, but the "run a hose to your balcony" is the difficult part for me. That means having a door open for 10+ hours at a time, which is a climate control challenge for the room. That's why I figured: Why not put the entire enclosure on the balcony, and then heat-humidity control the inside of it? Sure, more complex system and higher power draw, ... but maybe there's whole…

6" wide piece of cardboard that is floor to ceiling of the balcony door. Put it on the side where the door locks. Cut a hole near the bottom of it and stick the flexible tubing through it. Now you can shut the door and hold the cardboard in, while still maintaining the climate control. You can use something thicker than cardboard like the plastic version of cardboard... google: 'Corrugated Plastic Polycarbonate Acryl…

I appreciate this, the challenge is that the wife won't let me get away with that level of jank (the balcony door opens into the living room) ... :-)

In the next life I'll get a house and build it around the 3D printer.

Not quite on topic, but I wanted to start 3D printing for a long time, but it feels there’s a huge gap from where I am (0 knowledge of 3D modeling and obviously 0 experience with printing) and where I want to get (design some custom parts that would make my life easier, e.g. a custom support for my Magic Trackpad that integrates with my keyboard).

Does anyone have a good recommendation to go “from zero to hero”?

So I would really like to get into 3D printing, but I struggle with discomfort over the health implications. I live in a small rented apartment and can't easily work out space or, much more importantly, external venilation. Yes, I've looked into PLA vs. ABS, I've looked into enclosures with carbon/HEPA filters, etc., but I still don't want to have it in my living space without a vent to the outdoors. Here's the best…

I would be as concerned about the health implications of the sound. The constant background noise adds to the baseline stress level of the environment, and it's difficult not to intersect printing and sleep schedules. So I recently moved mine from the middle my medium sized house to the far end from the bedroom, behind a door. And even with that I'm considering enclosing it in a cabinet, to reduce the noise on that s…

The Mk3S (so presumably the Mk4) has a silent mode, which cuts down the noise significantly. I have mine on a 5cm×25×25cm paving slab which also helps avoid vibrations.

With a closed door between my bedroom and the printer at night, it's no problem.

You can do it non-jank. I just realized there are products for this (mostly around portable AC exhaust vents). Google 'sliding door vent kit'.

Or just 3d print a new wife? (joking)

That does look not-so-bad, but ... unfortunately we also don't have a sliding door. Nor sliding windows. Germany goes for those mechanically complicated multi-direction tilt/swing hinges instead. They're super mental (and metal), and break my aspirations.

I know, I'm not an easy customer.

I've seen too many terrible Benchys in reviews to fall for this one!

Original Prusa MK4 kit Out-of-stock :(

I have a MK3S+ with MMU2S, bear clone upgrade, a head upgrade, Octoprint with 2 cameras, a temperature regulation chamber, and filament dryers.

I hope it's not against any rules... it's not as far as I know of, so I plugged your comment into ChatGPT:

Sure, I'd be happy to help you get started with 3D printing! I'll break it down into a few steps, from learning the basics of 3D modeling to printing your first custom part.

Learn the basics of 3D modeling:

To start, it's important to get familiar with 3D modeling software. Two popular free options are Tinkercad and Blender.

Tinkercad (Beginner-friendly): Tinkercad is a browser-based, user-friendly CAD software that helps you create 3D models easily. It's perfect for beginners. Tinkercad tutorial: https://www.tinkercad.com/learn/designs

Blender (Advanced): Blender is an open-source 3D modeling software with a steeper learning curve but offers more advanced features. Blender tutorial: https://www.youtube.com/playlist?list=PLa1F2ddGya_-UvuAqHAks...

Understand 3D printing basics: Learn about 3D printing technologies, materials, and the process. This will help you make better decisions when designing your parts.

3D Printing basics: https://www.3dhubs.com/guides/3d-printing/

Choose a 3D printer:

When you're ready to buy a 3D printer, consider factors like build volume, material compatibility, and price. A few popular entry-level 3D printers include:

Creality Ender 3: https://www.creality.com/goods-detail/ender-3-3d-printer Prusa i3 MK3S: https://www.prusa3d.com/original-prusa-i3-mk3s

Learn to prepare models for printing:

Once you've designed your 3D model, you'll need to prepare it for printing using slicer software. This software converts your model into instructions for the 3D printer. Popular slicer software includes:

Ultimaker Cura: https://ultimaker.com/software/ultimaker-cura PrusaSlicer: https://www.prusa3d.com/prusaslicer/

Print your first project:

Start with something simple to familiarize yourself with the 3D printing process. Then, move on to more complex projects like your custom Magic Trackpad support.

Join online communities:

Participate in online forums and communities to get advice, feedback, and inspiration. A few popular 3D printing communities include:

r/3Dprinting subreddit: https://www.reddit.com/r/3Dprinting/ Thingiverse: https://www.thingiverse.com/

Follow these steps, practice regularly, and you'll be well on your way to becoming a 3D printing hero. Good luck!

I met someone building a similar trackpad! He's using a 3D printer to create the housing. https://www.reddit.com/r/ErgoMechKeyboards/comments/113rfhm/...

/r/3DPrinting has a comprehensive guide to getting started with 3D Printing: https://www.reddit.com/r/3DPrinting/wiki/gettingstarted/

The designing and iterating of physical components is a learned skill, just like designing and iterating on software becomes easier with experiences. Best way to learn is to just get started, and have tons of fun!

This is good advice. Tinkercad is hardly more difficult than Microsoft Paint and can be easy enough to start doing some basic DIY modeling in an afternoon.

Zero to hero... no not really. The printing part isn't that hard to pick up. The designing complex models with complex tools is a real mother. Youtube is a good place to start with tools like Fusion 360.
