Spool Holder AJB

Last crawled date: 4 years, 2 months ago

I used the "TUSH - The Ultimate Spool Holder" (https://www.thingiverse.com/thing:2047554) for quite a while. Love the simple design. However placing the spool on the two pieces did not satisfy me. They tend to move and so I looked for an adjustable spool holder. Many designs seemed to be just too complicated with spindles and sprockets, one using 7 or more ball bearings.
I wanted something as simple as the TUSH but more reliable and adjustable.
This is not a remix of the TUSH. It was entirely newly designed in Fusion 360.
This is what I came up with. All parts fit together really nice without additional sanding. The dovetail guide is snug fit. One piece is attached to the dovetail guide with one M3x8 countersunk-head screw.
The 608ZZ ball bearings (used for skateboards, get cheap ones) press fit and don't fall off. Need a bit force to push them on.
The two equal sides are pushed together and mounted with two M3x12 countersunk-head screws.
I added small holes for up to 8mm silicone self adhesive rubber bumpers used for cabinets drawers or doors. They securely prevent slipping.
The lever is eccentric and secures the second holder on the doveetail.
Let me know please if you can use that.
