Step 1: Creating the Frame

Picture of Creating the Frame
The frame was manufactured using 4mm thick laser cut acetate.

Files were created in Solidworks and exported as a DXF file - the format appropriate for laser cutting.

5 Sections were cut and using dichloromethane attached together.

spec and pictures to follow.

I made a similar pump to this using the laser cut laminated method about a year ago. Mine is really crude in comparison nice job. does the pump need to be primed before use as mine had to be submerged?
