Spool Holder AJB

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 8
