P3Steel Extras
There are a few extra items that can be added to the basic P3Steel assembly that make its use more effective:
Small bed leveling thumbwheels (low profile)
These small low profile thumbwheels with an embedded M3 niloc nut make bed leveling so much easier that they are considered almost essential (only 3 or 4 are needed, depending on the P3Steel frame version assembled).
Note that larger thumbwheels may not fit in the narrow space available under the P3Steel Y-carriage. These are tested and fit (Thingiverse 39459).
Filament spool holder
Again, you can live for a short while without this part but sooner or later you are going to add it to your P3Steel!
