A4 Mini Vacuum Table

thingiverse

A compact work area mini vacuum table designed for your CNC machine measures 297 x 210 mm in size, perfect for creating PCBs or other small projects. The device operates on a standard vacuum cleaner and produces a strong suction power. I've integrated my Vax bagless model into the system by fitting the hose into the Vac adaptor, which is securely held in place by the Vac retainer after removing the handle/wand attachment. Three holes are provided for inserting small screws or rivets into the retainer, but it ultimately fits together snugly without them. The table's base is constructed from 32mm MDF material, while the top is made from 6-8mm Acrylic. Before assembling the device, coat the inside of the base with varnish to seal it after cutting the channels and other features (refer to DXF layer names for specific cutting depths). Apply a bead of silicone around the Vac adaptor and under the bed as depicted in the photo. To attach the bed to the base, use self-tappers or M4 machine screws. The mounting points are spaced 160mm apart to accommodate my T-slot table; adjust this setting according to your needs. For optimal results, lightly skim the bed after mounting it securely in place.
