Lifting Weight Bushes - STL files

Recommended Posts

Lots of people use weightlifting weights to add extra mass to their mount counterbalance, but the 1" diameter holes mean they are a sloppy fit, even when sandwiched between two 'normal weights'. This creates the opportunity for them to slip, jarring the mount and possibly spoiling a sub.

Here's a solution - 3D printed bushes.The bushes fit neatly in standard weights and fit standard 18mmm or 20mm shafts.

A slight variation would be to taper the outside so that its slightly oversized the flange end.

That way the weight will create its own "Lock", to move it just lift the weight and slide the bush.

A possibility, but there may be too much variation in the bore of the weights as tehy are uaually pretty crude castings, plus I'm wary of relying on the bush alone to secure larger weights.
