Altered Antdroid parts by stuartm

My printer's 180mm round print bed isn't quite large enough for some of the standard Antdroid parts so I adapted them.
Tibia: These were slightly too long so I trimmed the cosmetic top part from the model in Meshmixer.
Top and bottom plates: I recreated these as SVGs to cut from 3mm cast acrylic on my desktop CNC router. They were drawn in OnShape (matching the original shape and servo mounting positions) before importing into Inkscape, tidying and exporting as SVG.
Body separator: The original push-in ones wouldn't work with the new 3mm perspex plates so I created some new ones to attach with M3 machine screws (note: design updated to reflect positioning of servo arms on top plate - they should be inside).
Camera neck: I created a small neck which attaches to the top plate with a couple of M3 machine screws and nyloc nuts. It accepts the standard Antdroid camera mount.
Camera mount: My Raspberry Pi camera didn't fit the existing mount so I designed an adaptor plate. It can be cut from fibreglass sheet or, if you don't mind the extra thickness, from the same 3mm cast acrylic sheet used for the body plates.
Bearing retainer: The specified 4x8x4 bearings didn't fit the femur properly so I made these retainer cups to hold them rather than buying a whole load of new bearings. YMMV but if you encounter the same problem as I did, print a couple of these per leg, glue them in place and press in the bearings.
The OnShape doc used for the body plates, body separators and camera neck is here: https://cad.onshape.com/documents/d2dcaa54893a61787c6f1bbf/w/f8e243d51c74b654bc73bc32/e/fe8624972b31a44e84f7f911
