Any 1.875 part?

There is a big gap between 1.25m parts and 2.5m parts.

Are there any 1.875m parts?

Orionkermin's Homegrown Rockets (a.k.a. HGR) is a Soviet/Russian-themed 1.875m set of parts, but it hasn't been updated for 1.0 (and may not be for some time, but you can keep track of the update process in the dev thread). Socke has made a more stockalike set of parts, but at the moment, it's just fuel tanks and a couple of structural and adapter parts (and it also hasn't been updated for 1.0, but since it doesn't have anything complicated yet, it's more likely to be okay).

With Tweakscale, it is not realy needed anymore as you can freescale all tanks/engies to 1.875 size

Tank parts can be scale up easily, but engines can not be scale up with RF mod.

Also, I want a cone shape command part rather than sphere.

But, thank you for your replies.
