Better fitting dovetail base

Hi guys,
Have an orion ed80 with dual speed gso focuser. I have put 2 dovetail bases on either side, 1 for finderscope and other for starsense.

Is there a more curved base available or one which sits better on the focuser with both edges touching the focuser tube.

Photo attached of how it is sitting now.

Regards
Kon

Might be a better price out there somewhere

Jeremy,
Looking at it, it seems like the radius on the base is to suit the outside diameter of an OTA, rather than the smaller diameter of a focuser body.

A few aluminium strips (cut from the Coke can) could be used as spacers under the locating edges......

Kon,
Just make sure the radius of the base is small enough to fit the focuser.

This is what arrived from ebay and fits much better.
