. 3dprint .stl files, and mill .dxf with cnc or laser.

You need
32x 4x30mm pan head wood screw.
gel / flexible glue for wather proofing. Do not use ca or anything that sets hard.

740x500x8-12mm wood plate
690x500x4mm acryl plate OR 2x 345x500x4mm acryl plate
600x400x2mm acryl wasteboard
THESE DIMENTIoNS ARE AFTER MILLING. USE A LARGER PLATE TO HAVE SOME TOLERANCES.

If you have a big enough acrylic plate, then machine AkrylicBottom and AcrylicBottomWithTap as one part.

WoodBase should be 8 - 12mm thick. Screwholes going trough the acrylic should not be drilled trough, so the glue will not leak out of the bottom. Leave ~2mm at the bottom.

Use a 600x400x2mm acrylic plate on top as the wasteboard. Replace when needed.

3dprinted parts has a slit for gluing to the bottom. Add glue and fasten with screws. When everything is assembled, then add glue to the opening in the dovetail joints. Just to leeakproof the gap betwean parts. You may need to repeat this after setting.

If using two plates as the 4mm acrylic bottom, then glue them down to the wood base for waterproofing. Use some 15x4mm wood screws to hold down the plates as the glue sets.

The Z-homie plate is so you can probe the wasteboard bead outside the waterbath. If you break a cutting steel during milling you will not be able to probe the workpease under water. Allways probe the Z-homie for consistancy. (Depending on your wood base, and thickness of glue, you might need to change the height of the Z-homie.

Hope you like, Happy milling!
