Topic Explanation:
The discussion revolves around the innovative use of 3D printing technology to create ostomy barriers, specifically focusing on creating minimal contact barriers that utilize a large foam O-ring instead of traditional adhesive bandages. The initiator of the discussion, Bob, is considering leveraging the resources available at his workplace's 3D print lab to experiment with this idea. He is seeking insights from others who might have embarked on similar projects or are interested in exploring this area, aiming to improve upon existing designs like the Nu-Hope adhesiveless urostomy barrier.

Advice and Helpful Insights from Replies:
1. Environmental Concerns and Alternative Approaches:
- One participant discussed their experience with trying to reduce the environmental impact of ileostomy supplies by ordering a custom-made, reusable ostomy barrier from Perma-Type. However, they found it difficult to clean and ineffective in sealing compared to disposable options from established brands.

2. Success Stories with 3D Printed Stoma Protectors:
- Another participant shared their success in using a 3D printer to create a stoma protective cover, which has been durable and functional for over five years. They designed it to be low profile and customizable based on the stoma size, and it functions without the need for a belt.

3. Design Innovations and Collaborative Efforts:
- There was a mention of a design idea involving an inner circle of "spider type fingers" that apply varying pressure to hold the O-ring in place, which would require wearing with a waist and groin belt for stability. This idea is still in the conceptual phase, and the participant expressed interest in exchanging ideas and collaborating with others working on similar projects.

4. Interest in Sharing and Expanding on 3D Printing Files:
- Another forum member expressed interest in obtaining the 3D printing file for the stoma guard to try printing it themselves, indicating a community interest in sharing resources and designs for personal use and possibly wider distribution.
