The most important accessory is a backup 3D printer so I can repair my main printer

Something that might be confusing for new people: What he calls "hotends" in this video are actually nozzles, they are something that goes into the hotend. Otherwise, great video!

isopropyl is my favorite chemical ever since i got into airbrushing miniatures, soldering pcb's, cleaning my pc, cleaning 3d printer/machine/tool part. its such a versatile cleaning tool

I learned the hard way how important IPA (not the beer, though equally important) cleaning the print bed makes all the difference. When I first started out with 3D printing I started noticing poor bed adhesion, and quickly realized that nothing would stick to the exact spot where I would place my thumb to break my prints off the bed. When this finally dawned on me I decided to de-grease the print bed with IPA using a coffee filter. Coffee filters are lint free and therefore a perfect solution.

Great video! One thing that I got recently was a 3D printing pen. Helps to fill in or fix tiny portions of a print without having to reprint the entire item. But, it does take some skill to do it neatly and it's hard to fill in a spot 100% (no holes) without a couple of layers.

A soldering iron for fusing prints together 👍

[Collinormous]

WHAT?! I've just been throwing away my failed prints -- and I have a pair of calipers already. Thanks for the tip!

[Moyersteven]

Great video! I use ALL these tools too. I actually use my hot glue gun to help with supports sometimes. I like to print statues and bust. The supports can be thin or sometimes ive had a support break off 6 hours into a 16 hour print. I hot glued a trash piece of PLA in place and it worked perfect. Nice thing about hot glue is it peels right off the prints without leaving any marks.

First 3d printer tool video ive seen that shows you actual useful stuff instead of dumb prints like little drawers to put on your printer. Good video!

A lot of 3D printer tools can be 3D printed. I made a "radius gauge" - basically a set of flat pieces of plastic with a quarter-circular bump and a quarter circular-cutout in every size from 1mm up to 20mm. When you're trying to design something for 3D printing that has to mate up against some real-world object that has curved corners or whatever - these are PHENOMENALLY useful. I threaded all 20 of them onto a key-ring...super-handy!

Thank you for these tips! . Upon your invitation to share: I myself use a 19" server cabinet.. this allows to buy 19: rack lights with 2 foldable arms, readily available and mounted with 2 screws. Also I use an internal 19"powerstrip. The printer is on an extendable drawer plate (standard available in server cabinets) I lined the server cabinet with acoustic foam (adhesive/mass/foam- three layer material). The filament goes through a hole in the 'roof', and is suspended on a loose alu stand with rubber feet for easy acces. The cabinet has 2 fans that can be ducted to the outside air (for non-pla printing). Most features are available in patch cabinet configurations, apart from the foam I suppose (akoustic shop) .

[Tannius]

I can't believe I never thought of the hot glue gun trick! So simple yet so useful! When I think of the filament lost over the years because of poor bed adhesion... Also, turning your closet into a print center inspired me as well. Thanks!

It's worth noting that PLA held near the glass point for extended periods may leave behind an extremely small amount of oils which build up overtime, often resulting in eventual but sudden complete refusal for first layer adhesion. It took me forever to figure it out the first time this happened as I never touch the bed. But, of course, a bit of iso cleared the issue right up.

I use a guitar pick quite regularly. It’s good as a scraper to remove thin bits from the builtplate, when flexing it wont do.

your videos have been so helpful, thank you!! I got a Crealty Ender 3 Pro from my husband for Christmas and he wanted to set it up the next day and start using it. I decided it was a better idea, since neither of us had even used a 3-D printer, to look for videos to get tips on the entire printing process. I watched videos from a few different channels and wasn't getting actuels tips and advice for someone with no real knowledge of 3-D printing. I finally found your channel and am so glad I did. Your videos are actually helping me understand how the software and printer communicate and how the printer uses the data to create an object. I can't tell you how much more confident in my ability to print I am. Thank you Nils!!

Dang he even muted himself when he said Alexa!!🤯

[hotends]

Great tips pointing out the print saving technique! it would be nice to see the trick in several slicers to cover more bases.

[joshuabray]

That’s a great list. It’s also good for CNC’s and Laser cutters. I even use a lot of those in woodworking.

[eugenewii]

First thing I printed after my initial testing was printer tools and replacement parts before something went horribly wrong.

Example of I don't have these tools yet, a rulers, hole gauges, torture tests, printer printable parts. These could help compare to diagnose and repair a problem.

I found a video last weekend where someone set up octoprint for an android phone. I got bored and tried to set it up, and it's been amazing so far.
