I will introduce a few good mods here that can also improve your printing results or make your everyday life easier.
Brush Mods
Bedleveling Brush
I occasionally had problems with the first layer. This was due to a dirty nozzle. Unfortunately, the normal cleaning process didn’t always help. With this mod, however, this problem is history.
Toolchanger Brush
Especially with multi-color printing, the nozzle tips can become more dirty, causing impurities in the print image. With this mod, the nozzle is cleaned with every tool change. However, you still need to dry your filament 😉
Magnetic Filament Sensor
This mod is also a must-have, especially if you want to print PETG or TPU. Flexible filament can now be easily fed through the sensor, and PETG no longer squeaks. This reduces the friction on the filament.
Extruder Main Plate
This plate is also worth considering if you’re disassembling your extruder anyway. It covers the slot on the side where the filament is fed in. This prevents filament from getting in there. This is especially important for flexible filaments. I had these parts printed in PA12 using SLS.
Note that you’ll need to open the planetary gear to do this. To avoid damaging it, you’ll need a 3D printable part. You can find this on Printables.com under “Prusa XL printable parts.” Please read the Prusa instructions beforehand.
Nozzle Fan Duct
Maybe you’ve already noticed. The original nozzle fan duct isn’t exactly great when it comes to cooling. So, a different fan duct makes sense. I had this printed in SLS PA12.
Toothed Pulleys
You may have noticed that there are two idler pulleys in the X-carriage, where the toothed side of the belt is guided over smooth idler pulleys. Why Prusa doesn’t use toothed idler pulleys for this is a mystery to many. This can cause the belt to deform. Therefore, it is recommended to use toothed idler pulleys.
CoreXY Parts
Unfortunately, the Prusa XL will still be shipped in 2025 with PETG parts in the CoreXY part, even though Prusa recommends printing the parts in PC-CF on Printables.com.
This mod is significantly more stable and rigid than the original. The pulley axes are also firmly attached.
Especially recommended when using an enclosure. It works with the new Washers.
Anti-overheating mods
In regions with high temperatures, the Prusa XL may experience overheating errors. IPIND 3D has already provided suitable solutions for this.
Fot the Heatbed Controller
For the Buddy Cover
Tools
Here I list some important and useful tools.
Daily Tools
Calibration Tools
I also have a collection on Printables.com: https://www.printables.com/@INVESTEGATE/collections/822155
If you think that an important upgrade, mod or tool is missing, please write it in the comments below 🙂
I think you should really add the Heat Bed Controller cover “cooler” (https://www.printables.com/model/1286108-improved-prusa-xl-heat-bed-controller-cover-remix) and the Buddy Cover colling mod as well (https://www.printables.com/model/859870-improved-prusa-xl-buddy-cover)
Both have taken my printer’s uptime/reliability so much higher…
Hey & thank you 🙂
Where do you live? I’ve heard about this mod a lot, but I’ve never had any problems with it. The mod probably only makes sense for warm to hot countries. It doesn’t get warmer than 26°C in my printing room.
