Shelf Spool hanger

thingiverse

Update: February 6, 2020: -A printable "Spool Roller" has been added for filament spools, which can be used with 6700zz bearings. It will also work without bearings. -Additionally, a "Hanger Locking Block" has been included to set a fixed distance of 13.5mm between the hangers, which can be locked using wood screws or M5 bolts. February 4, 2020: A shelf hanger for filament spools was needed, so one was made. It should fit shelves from 14-43mm with the use of different spacers included. -Print the holders and choose the spacer you need for your shelf! Hardware Needed: -A 10mm axle that fits the design of the hangers. A length of 18.5cm "bathroom" 10mm zinc-plated copper pipe was purchased and used as an axle, which was then cut to size. -Optional: 2x 6700zz bearings for a roller with bearings. Note: Be careful when assembling bearings on the axle/bearing housing; use proper tools to avoid seizing. 2x M5 bolts or 2x 4mm wood screws are needed for the "locking block". -Print 2 "bolts" and "spacers". These should not require any further scaling, as they have been designed to fit loosely. -Print 2 "end stoppers" and force them onto the axle ends to prevent the spool from falling off. This is unlikely to happen, but it's a quick print for peace of mind. -It's recommended to print the "locking block" to secure the hangers at a fixed position of 13.5mm, even though some users have successfully used them without any issues.
