Reddit reviews SIQUK 3 Pcs Teflon Tube PTFE Blue Tubing (1.5M) with 3 Pcs PC4-M6 Fittings and 3 Pcs PC4-M10 Fitting Connector for 3D Printer 1.75mm Filament

What you absolutely MUSTTTTTTT!!!! order? Nothing. The printer works as is. But if you want to do yourself a favour, here's a list of what I consider essentials:


- New springs, both bed and extruder. I don't have a link for an extruder one as I upgraded my entire extruder drive frame and that came with a better spring

- A new removable bed. Creality glass bed or glass with a PEI sheet is my bed of choice

- Thermal pad to avoid the annoying bed clamps. Cut squares out of it, lay them in a checkered pattern alternating between thermal pad and nothing and place your bed on top. They will hold the bed in place and help with heating

- Stepper dampers if your printer is anywhere near where you spend your time, it sounds like a bloody jackhammer right out of the box

- New tube fittings, the stock ones are terrible and will give out in a matter of weeks at best. They also barely hold onto the tube

There are a ton of other great upgrades, but I think a good idea is to get a feel for it yourself.

What you can do, however, is check out some printable upgrades. I have this thread where people contributed with their choice of printable upgrades. It's a great list you can refer to later. Essentials on that are the fan guard and LCD back cover simply because the Ender 3 as is has the fan and back of the LCD exposed and that makes it crazy vulnerable to dust and gook damage

This is what I bought

Those couplers are trash and so is the PTFE tube they sent. They may work for a while but you'll want to swap them sooner rather than later. Here's a list of upgrades you'll probably want to do. You'll also want to look up a tutorial on how to upgrade your firmware so you can activate safety features (thermal runaway protection specifically). This also doesn't include a BLTouch or EZABL (auto bed levelers) as I have yet to make a choice personally.

Aside from the aforementioned glass plate, there are several easy and useful mods. There's many threads going over this actually. Search around.

Get this and make some mods using the bearings. I made the Filament Guide along with a snap-in filament guide for closer to the spool. Both highly recommended.
Also using the bearings, I made a Spool Holder. Not crucial, but might save wear on extruder mechanism.

Get This or something like it and at least install the couplers instead of stock ones. I haven't replaced the tube itself yet. It requires fairly precise cutting but you can get PTFE tube cutting guides and cutters printed from thingiverse.

Get This and install it before glass bed or anything else, except for maybe a bed handle (which you can print from thingiverse. Handle isn't crucial but will help.

I haven't yet but will get:

• a better extruder (all metal or a bmg clone)
  
• a better hot-end (for printing of other stuff, like nylon if I want)
  
  Buy Spare Nozzles, including a hardened steel one if you want to do any amount of printing with wood-grain, metal or glow-in-the-dark material.

This is where i got them from. Just make sure when you cute them that you are careful not to crush the tube. https://www.amazon.com/gp/product/B07FPJHRTQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Here's the extruder I bought

And here's the bowden tubing and connectors

There's a lot of similar items on Amazon that will work; I just personally went after the popular ones with the highest reviews

Also, if you get the tubing, don't forget to get cutters if you don't have any already

Here you go.

Stock Hotend, This Bowden tube and the change I mentioned in my top level comment

https://www.amazon.com/SIQUK-Fittings-Straight-Pneumatic-Connector/dp/B07FPJHRTQ/ref=mp_s_a_1_1?keywords=ender+3+couokers&qid=1566384028&s=gateway&sr=8-1-spell

Basically these. The ones that came with my printer couldn’t hold the tubing which made the printer unusable. The yelllow bed springs are similar - the stock ones are flimsy and may require you to cut some plastic on your z end stop to make it work out. To me those are really the only 2 “day one” upgrades just due to them sometimes being necessary for the printer to even function.

This is what I got after a few test prints I'm trying the skull again. It looks way better.
