I’ve been working on a small MVP around something I keep seeing in 3D printing: replacement parts for products that are broken, discontinued, overpriced, or just annoying to source.

The idea is basically a searchable database/marketplace organized around the actual product rather than just STL files.

So instead of searching something like “replacement gear STL,” you’d browse:

Brand → Product → Model/revision → Part

A listing could be an STL you print yourself or a physical printed part from someone who makes it.

The part I’m most interested in is compatibility/trust. Things like whether somebody has actually printed the part, what product revision it fits, material used, whether it survived real use, installation notes, etc.

I have a rough MVP now, but before spending much more time on it I’d love some criticism from people, else than me, who actually print/repair things.

A few things I’m curious about:

• Have you ever tried to find or make a replacement part for something you owned? What was the hardest part?
• Where do you currently look first: Printables, MakerWorld, Thingiverse, Google, Reddit, somewhere else?
• Is finding the STL actually the problem, or is figuring out whether it will fit/work the bigger problem?
• I know it is a 3d-printing community so it might be biased but do you think that offering the possibility to download the file or actually buying the physical part is less a thing?
• What information would make you trust a replacement part made by a random person?
• What would make a site like this pointless compared with the platforms that already exist?

Hey everyone,

A few months ago I posted here about a side project I was building to make pro CS matches easier to follow: https://www.reddit.com/r/esports/comments/1sn8g11/i_built_a_live_cs_overlay_to_make_pro_matches/

The idea was to add some of the context I personally felt was missing while watching CS: round history, economy, buy types, opening kills and conversions, player stats, match patterns, explanations of what’s happening, etc.

Well, after a lot more work, ClutchLens is finally at the point where anyone can actually use it:

I’m posting this less as a “hey, I launched something” post and more because I’ve reached the point where my own opinion about the UI/features is becoming pretty useless 😅

I know where everything is, I know what every graph is supposed to mean, and I obviously know why I built each feature. What I really need now is to see how other CS viewers use it without that context.

In particular, I’d love to know:

• What do you actually find useful while watching a match?
• What do you open once and then never look at again?
• Is anything confusing or unnecessarily complicated?
• What information do you wish was there?
• Would you actually keep something like this open while watching pro CS? If not, what would need to change?

I’m also looking for a small group of people who are willing to properly test it and give me feedback over time. I would, of course, provide those beta testers access for free. I’m much more interested in getting useful feedback right now than anything else.

If you’re interested, leave a comment or DM me. You absolutely don’t need to be some CS expert either, feedback from newer/casual viewers is just as useful if not more, because part of the reason I started building this was to make competitive CS easier to understand for everybody.

Any criticism is genuinely welcome. If something feels pointless, confusing, annoying, or badly designed, I just hope that it can improve the viewing experience for all of us.

Hi everyone,

A few weeks ago I shared a personal project I’ve been building: a live CS overlay aimed at giving viewers more context during pro matches.

The idea is to make it easier to follow things like round history, economy evolution, buy types, openings-to-round conversions, assists, and other details that are usually hard to track while watching.

Here’s the original post for context: https://www.reddit.com/r/esports/comments/1sn8g11/i_built_a_live_cs_overlay_to_make_pro_matches/

The long-term goal is still to make this available through Twitch broadcasters, so viewers can access the extra information directly from the Twitch interface while watching a match. But as a first step, I’ve now made a technical demo available here:
https://clutchlens.tech/

It’s set up for IEM Cologne Major 2026, so this felt like a good opportunity to put it out there and see how it holds up during a real competition.

There will probably be bugs, and I’ll try to fix them as they come up throughout the event. I’m also very interested in feedback: what feels useful, what feels confusing, what is missing, or what you would actually want to see while watching competitive CS.

So if you’re curious and want to try a different way to follow pro CS, feel free to check it out. Any feedback is welcome.
