Printer hardware upgrades

The texture is similar to the Prusa sheets but results in a more porous looking finish on PLA and PETG.  On Reddit and Amazon, customers claim that it is easier to print with these sheets comapred to the original Prusa parts. Regardless of which textured sheets you choose, your parts will look far more professional with a textured sheet than regular smooth sheets, but some added care is needed:

Cost: ~$30-40

Install: 2 seconds

Ever get blobs of filament sticking to the nozzle? Or have a difficult time keeping the extruder at a constant temperature when the part cooling fan is on?

Put a sock on it!

These little beauties just clip onto the heat block and keep everything clean and at the proper temperature. They don't last forever and will eventually crack or deform from so many heat-cycles, so best to keep a spare.

Cost: ~$2 each

Install: 1-5 minutes depending on which part cooling shroud you have installed


In case you want to use a V6 nozzle on the Nextruder, install it together with this nozzle adapter.


Cost: ~$30

Install: 20 minutes

An enclosure helps to maintain a consistent air temperature around the printer resulting in more reliable prints for PETG and ABS. It also reduces noise and smells. You will need to cut a small hole to pass the power cable through.

Cost: ~$30-40

Install: 5 minutes

Spare Parts

Some printer components wear out so it's best to have a few spares:
