I’m a math and biology major trying to create a 3D printed version of a hatch used for cleanly transferring materials (so mold stops entering and killing my cultures). The design is relatively simple, but I have limited experience with Blender and would like to parametrize it in case design changes need to be made. This type of hatch (DPTE) has been around since the 70s, but I can’t find any full schematics for it (probably because companies want you to buy theirs). I have attached links to a PDF with a basic drawing of the schematic and a video showing a 3D animation of the hatch in action.
Normally I would buy something like this, but since it’s a low-volume item (and from the biotech world): the cheapest hatches sell for at least $750 on eBay.
If anyone could give any advice it would be greatly appreciated, as it would also help Open-source Science and Biohackers. Thanks!
