Bondtech upgrade kit for Original PRUSA MK3S printers

Bondtech LGX Shortcut Copperhead for Prusa MK3S

The advice is: try, change, experiment.

Thanks to this, you get the possibility of greater flexibility in printing. In the basic version of the MK3S and MK3S+ printer, you will find the E3D V6 hotend, thanks to which there are many possibilities to exchange and test parts. With small diameter nozzles, you can print small prints with fine details, and on the contrary, with a large nozzle, you will save time when printing a bulky model.

In more detail, it is worth mentioning the X E3D V6 nozzle, which is made of tool steel that is nickel-plated and hardened. This material will help the nozzle maintain high hardness even at high temperatures. And you don't have to be afraid to use it even when printing with abrasive materials (such as PETG Carbon), which cause abrasion with ordinary nozzles. But the fact remains that you pay extra for this type of nozzle.

Another option is the Revo Prusa MK3 Edition (from the RapidChange Revo series), which was launched in 2021. Thanks to an easier way to change nozzles and a new heating block that reduces the risk of heat leakage, the Revo has gained popularity. You may need to make sure your printer voltage is compatible with this model, however the Revo hotend has been designed by E3D to allow easy upgrades for Prusa MK3 printers.

Along with the launch of the MK3S printer came a new Einsy Rambo motherboard that supports direct Raspberry Pi Zero W integration. With a few printed pieces, you can plug the Pi into the back of the printer motherboard and run OctoPrint with some limitations. This will enable powerful print control over a wireless internet connection. But it is worth mentioning that there were performance issues when running OctoPrint on the Pi Zero W. You can find more information in the official guide from Prusa.

If you are afraid to move away from your printer while printing, you might be interested in a surveillance camera.

After all, even such high-quality printers as the Prusa MK3S and MK3S+ can experience a defect during printing. A surveillance camera with appropriate software (such as OctoPrint) offers a solution. You will find a range of cameras in the market in different price ranges. Among the favorites is the Raspberry Pi camera. Whichever you choose, you'll need a bracket to mount it so it can properly capture the print area.

Access to the motherboard on the Prusa i3 MK3S/MK3S+ printer is not quite ideal as the board is angled towards the printer. That's why an upgrade was created in the form of the YZ cover, where the base plate turns 180°. This creates more convenient access to the board for possible repairs or modifications. The case also functions as a support for the frame and thus ensures greater stability for the printer.

You can print the cover yourself, just get inspired by the project on printables.com. Even the project itself has already gone through changes, as some users pointed out problems with cable attachment.

The modified filament guide ensures a smooth filament path from the spool to the extruder. The wire is attached to the top of the printer frame. Due to its sufficient size and rectangular shape, it will keep the filament in the right place even if you print with multiple filaments at once.

This is another upgrade that you can print yourself, the instructions for it (including detailed information on printing) can be found right here.

Some users have reported a problem with the cable leading to the heated pad - after a while it started to sag and touch the frame of the printer. And that was the reason for the upgrade in the form of a simple cable holder.

Its printing and installation will be absolutely simple, just look at the instructions that are prepared here.

 It's a gimmick that has more of a visual reason, but could still excite some users. The extruder motor is fixed to the printer in a clearly visible place. Behind the motor cover, the axis rotates, which pushes the filament through the nozzle. You can mount the indicator from the other side of the motor and observe the axis rotation speed to verify that everything is running as it should.

After printing the indicator on its raised side, stick the magnet with glue and fix it on the extruder. You can play around with the design of the indicator vanes. Tips on what the indicator could look like are waiting for you on the myminifactory.com.

The feet, which are included in the basic equipment of the printer, are relatively soft. This can cause the printer to vibrate during printing, and as a result, the printout could be damaged. This problem is solved by printable feet, which are designed to reduce the vibration of the printer and keep it in place. 

You can read the instructions for printing on Thingiverse.

And if you don't want to start replacing the legs right away, there is another option - to install fixings to the legs. The falling off of the rubber feet every time the printer is moved can lift many a printer out of his chair. If this happens to you too, you will definitely be pleased with the following gadget - a fastener that can lock the legs in place.

You can print and install it in just a moment and save yourself a lot of stress. Print instructions are right here.

Another accessory that you could add to your 3D printing equipment is a printer box. There are several reasons why you should decide to buy a box: 

• you turn down the noise
• you will reduce the spread of odors during printing
• less dust and dirt will get into the printer
• and the main one – you ensure stable conditions during printing, such as temperature and prevention of drafts

You can find an article directly on the Prusa website that deals with the production of a printer box (you can view it here). This box combines printable material, furniture and accessories from Ikea. In the article, you will also find which electronics you should use and which tools will be useful for making the box. And for those who don't have the time or desire to build their own box, Prusa has a simple tip - a photo tent that you don't need to modify in any way and will do its job.

If you have a printer in a darker room, or if you get to print later in the evening or at night, you've probably already thought about how the printer could be better lit. You can use a classic lamp for this, but more practical will be LED strips that you can stick on the frame of the printer or print out holders specifically designed for LED lighting. Another option is to attach the light to the printer box. LED strips can be found in various electronics stores and are not expensive at all.

You will find that with a well-lit printer, it will be easier to change the nozzle or do other maintenance.
