A couple of nice rapid prototyping design images I found:
Universal stand-alone filament spool holder (Fully 3D-printable) v10
Image by Creative Tools
A fully 3D-printable rotating stand for filament spools, created to be simply made with out the need to have for fasteners such as screws, nuts, shafts, glue, and so on. Every single component in this spool holder comes correct from your 3D printer’s filament.
The spool holder’s spindle is shaped to fit the vast majority of generally used filament spools with shaft holes ranging from 16 mm to 62 mm in diameter. It is also compatible with spool-significantly less filament coils.
The spindle which holds the spool’s weight rotates on its personal roller wheels, which makes it turn effortlessly.
The spool holder included an arm for filament guide tubes of each typical sizes 1.75 mm and three. mm. The arm also contains a pocket for inserting a piece of sponge which acts a a filament filter – therefore maintaining the filament clean and lubricated.
– Simple to 3D print
– Needs no glue or fasteners
– All parts can be 3D-printed
– Fits practically any filament spool size
– Has constructed-in filament filter!
– Can also hold spool-significantly less filament coils
Next time you require a new filament spool holder, just 3D-print one particular!
