A larger, deeper belt clip for gluing (Goop or ShoeGoo works well) for attaching to DIY phone cases, etc. Update: added another version with more and slightly deeper holes on the back for more grip.("Sources" field is not working for me: new CAD, but inspired by http://www.thingiverse.com/thing:35940). I needed a deeper/larger clip and one with more aggressive hold. Print with high infill for strength since this will get flexed and abused. This design is made for a typical thin dress belt; may require scaling for heavier belts. The 6 divots on the back face are for gluing to shallow rivets or similar structures penetrating through back wall of the case. Update: new version has more holes for more grip, when not using rivets, etc. Will post vid and possibly other sizes/styles ASAP.
