Description
This is for a 1.75mm filament spool, but I can make one for a 3mm filament spool if you would like, just let me know. This filament cleaner and straighter features a long tube with a decently small enough tolerance as to not scratch the filament that straightens out the filament, a beveled lid that ensures that the filament will always go to the exit, no matter the angle, models for just the straighter or the cleaner, an all-in-one, and a smart design that allows the user to print with NO SUPPORTS! If you have a good printer, don't worry, but if yours is average, size everything up to ~110%. You might need to play around with the sizing a bit.
This is for a 1.75mm filament spool, but I can make one for a 3mm filament spool if you would like, just let me know.
The bevels are 4mm, 2mm, and 3mm (bottom up order) in diameter. It features a perpendicular angle, as well as plenty of flat surface to glue the design onto the printer if needed. I personally did this. You may not need to glue the design down, so there is a no glue area design for a slimmer look. Let me know if you need anything special or a place to put a screw.
Please like, download, and comment! I spend hours on each design, and I print each and every single one. When they don't work and you don't let me know, or they do and you don't like, it lowers my chance of knowing how you guys feel and makes my future designs less likely to be very good. Thank you
