It's expandable and the depth of each drawer is easily configured to whatever depth you have on a shelf or workbench.

Modular Filament Storage System - Part 2 (Installation)Robert Cowan2024-03-10 | I needed a better way to store my filament so I designed a modular filament drawer system. It's expandable and the depth of each drawer is easily configured to whatever depth you have on a shelf or workbench. Check the design files below on Printables for full list of materials and assembly guide.

All of this resulted in pretty decent results I can live with. Some printers just need some time to get the firmware right, which is really unfortunate. But overall, it's a very usable printer for certain application.
I went with a Trianglelab CHCT-OT hot-end with the ZS MK8 Plus nozzle (which is actually a CHT, or at least mine was). Below are some links. I'm not affiliated in any way, I just bought these on my own. You can buy directly from Trianglelab, but shipping is VERY slow (a few weeks), or directly through my affiliate Amazon link. If you buy through Amazon, you might want to also get a 'real' CHT nozzle from Bondtech which would most likely get you some additional flow rate. I just went with the cheapest route though.

For the pre-filter, only a small portion of it is actually getting used due to how the inlet is designed. Armed with some filament and a 3d printer, I'm going to fix this. Most laser air filters seem to have this same design, so this process should work on most of the filters on the market.

Thankfully I have a few 3d printers, so I can fix this massive shame on my household. Designing your own parts is the greatest part of owning a 3d printer, you just have to keep in mind what you're trying to accomplish.

Yes! It's one of my favorite tools and although it's not perfect, it's a good fit for me and for how I use a CO2 laser in my workshop. Obviously everyone's needs will be different, but it's been a really versatile machine that does what I want it to do.

The link below on Printables has PDF drawings, cut list, and a list of all the materials needed. This rack holes 15 totes and can be easily wheeled around the shop.

I had originally planned on doing this, but couldn't figure out a solution that still allowed me to be lazy. So I came up with the Filament Sample Card, which lets you easily (and quickly) make cards that show what's inside each drawer.

I try to print PLA, PETG, two different TPUs and PET-CF all in the same part. It goes well for the most part. I discuss slicer settings, challenges with wipe towers and more.

Since I only had a 2 toolhead machine, I decided to upgrade to the full 5 toolheads. In this video, I'll show you the installation and calibration process for the extra toolheads and do a test print to verify everything's working properly.

This video aims to answer this question. The answer really depends on what you're looking to do, what your needs are, and how you intend to use the machines. There's no single printer for everyone!

These shelving units are heavy duty and can be found at Lowes and Home Depot. I should be able to fit all 3 of my printers on them as well as all my filament.

I tried using a $4 shower curtain liner to control drafts and it worked out well enough for my purposes. Do you absolutely need an enclosure for your 3d printer? Not always, as long as you can properly control your ambient temperature and can put up with some minor quality issues.

I got a shaking mechanism off Amazon, added a motor and a timer module and now I'm living like a king. I just need to press a button and wait until my spray paint is perfectly mixed.

This year I'm finally making a spot for all my table saw accessories and decided to 3d print a holder for my dado stack. In this video I go through my design process and show that PLA can be perfectly fine for strong and long-lasting parts, with a little reinforcement.

A lot has changed with 3d printers over the last few years, so this guide should cover most of the basic information needed to be successful.

This video really isn't a comparison or a product review, but more of an explanation why I ended up buying it and how I see it fitting into my 3d printing workflow. The X1C is nice, but I want something a bit bigger and I'm curious if the K1 Max will serve my purposes. Listen to me ramble and try to justify my purchasing decision!

Would a 0.4mm nozzle print better? Yes. I compare the same prints with the same filament but use a 0.4mm and 0.6mm nozzle and find out that the 0.4mm nozzle gives me the print quality I was missing!

It might seem obvious once you've used them for years, but with 3D printing gaining such popularity, not everyone is familiar with the common tools used for transferring a part into CAD.

Overall the process is pretty straightforward, but in this video I show you what I learned from creating a part, slicing it, and finally printing it.

I got it assembled and have some very early impressions of it. Since there's not much out there about the printer, I wanted to give my thoughts an impressions. There's a LOT of competition out there, especially at this price, so I'm trying to determine if it's worth buying an XL, or if there are better options out there. I have no affiliation with Prusa, just some past experience with their printers.

It's a non-traditional combat robot in that it's not meant to actually 'win', but it's meant to get knocked around by other bots and survive. It's essentially a crash-test dummy, a bullet sponge, or the target of everyone's aggression. In this video series, I attempt to make a truly indestructible combat robot.

It's a non-traditional combat robot in that it's not meant to actually 'win', but it's meant to get knocked around by other bots and survive. It's essentially a crash-test dummy, a bullet sponge, or the target of everyone's aggression. In this video series, I attempt to make a truly indestructible combat robot. For this video we take a closer look at THE LOBOTOMIZER!

In this video I finish off the rear and bottom panels by using my CNC router for all the holes and cutouts.

However, to fully utilize the full potential of these features, you might need to purchase some of the accessories including the riser base and the automatic conveyer feeder. In this video I talk about those accessories, show you how they work and give you my impressions of them.

Instead of a pedestrian switch or knob, I decided to go with a TTP223 integrated into the faceplate which makes the faceplate touch-sensitive. It's a slick way to add a simple and intuitive user interface to your project.
