request to support larger and stronger springy servo

request to support larger springy push down servo

feature request to support 28mm wide servo or even larger servo ? thanks. currently it only supports 23mm servo (22.5mm) I printed and installed springy for a few months now, I found that the 23mm wide MG90S micro servo sometimes cannot move to "down" position, because the spring resists and move the arm back. this causes a lot print failure and not easy to debug, until you look at the servo arm and notice it's not in fully DOWN position, especially in multi-color print.

Maybe the 23mm wide MG90S micro servo is too weak, and cannot provide necessary force to push down the 1mm strong spring. The work around is to tweak with the spring length, cut and try. and I also have to use 0.8mm diameter spring ( instead of the 1mm in design). applying grease on the arm and tophat also helps. but all these dont address the root cause, a stronger servo should be the best solution.

There are some servos slightly larger 28mm wide in market with cheap price, should be stronger and better. for example https://www.aliexpress.com/item/1005003643468291.html?spm=a2g0o.cart.0.0.5cfb38dapkgguq&mp=1 17g metal gear

Maybe 33mm servo is even better,
or, 36mm or 40mm servo is too large to fit ? Thanks!

This request was originally opened for Springy project because no step file is available and seems that project was dropped/abandoned. Now that we have ERCF V2 , the frame is much stronger, and the CAD files are available....seems should make more sense and easier. Just open this request maybe many other users need it as well. Thanks.
