$120: laser-cut MDF parts only (you will need to cut plywood & 2x4 box or otherwise mount these parts; the rest of the parts are available at home depot for around $100)
$240: all parts but glass, needing only screwdriver assembly
$300: fully-assembled machine minus glass
Each machine is made by hand and can be customized, therefore I can incorporate some improvements to the original design for an additional cost.
I can use any specified glass size
I can use hardwood plywood instead of MDF, if you pay for the more expensive material.
I can add counterweights so the V-cradle is easier to lift.
I can add a motor and sensor to push the camera button.
