Indeed, condolences and best wishes to all. It’s a rough and sad situation.
Given that Aleph Objects is working to liquidate existing inventory before ceasing operations October 31, restocking unfortunately seems unlikely, unless maybe a buyer for the company is found.
Some vendors in the community such as IT-Works 3D stock various parts. My company Libiquity plans to sell wiper pads and possibly modular glass/PEI surfaces and other parts.
