OpenGrid Polygon MultiConnect

I have been modeling some quick opengrid holders, and I do like the multiconnect wedge for mounting instead of printed in snaps. However the rounded semi-circle on the multi-connect makes it hard to print a part flat (with the multi-connect standing). 

So I made a variant that is a polygon warping the original circle profile. should give plenty of grip and easy to print without support. 

The models are what I used to cad other holder with. I based them off the Multiconnect Modeling Files/quick-connect-top-back from the origional opengrid files. the -1 type is a polygon with worse overhang of 30deg. The -2 type is a 45deg (like octagon). 

Here is the onshape file if anyone want to directly use it https://cad.onshape.com/documents/03cc22d7b1fe31eab85f9bd1/w/314be73aaabfa01a106b23f1/e/52aaa27b41541dbeccbea722?renderMode=0&uiState=69702f8904def87866ef4a29
