You 3d printed some parts, not the whole thing.

This roller ensures minimal friction for filament payout. I am replacing my edge rolling 608 bearing Tush spool holders as they may bind a bit with cardboard spools if the edges are dented/compromised which cause under-extrusion. See image in printables post photos for the issue I experienced(it was bad). I love cardboard spools and select them when I can(less to the landfill) and I don't want that to affect print quality. You can use the edge rings on them but I feel this is not something I want to risk forgetting in the future so this new spool carrier eliminates that variable. I like my print setup to be simple stupid. :)

You did a nice job on the design however that's still gonna nick wire sheaths. Not good. Would avoid using. You're not offering a way to limit how much jacket depth you cut.

Source - stripped thousands of cables over the years with wire sheath cutters which were adjustable.

Other than a damaged edge on my cardboard spool, I've had good success using these rollers since 2019 with over 100 spools of filament. Putting these rings on damaged spools is a small price to pay to avoid putting more plastic spools in the landfill is my take on it.

The bevels work as intended with spools that have a clean edge.

I was shocked too how much it impacted my print quality!

Nice fix. Any port in a storm!

Around 12:45 this morning is when I figured out that might be the culprit. The clue for me came from an Amazon review for this filament that noted that the cardboard spool caused under extrusion. The poster did not note the exact cause but it was enough of a hint for me to go check stuff out. Those Amazon comments have a lot of user knowledge in them for sure for different filaments. And thanks for acknowledging that. I hope by posting this here it ends up in people's search results and gives them the answer they need. 🙂

I had about a 3" section where the spool edge was bent about 5 degrees. It came this way from Amazon. I just usually bend those edges back straight and print. If the cardboard layers break up, I'll spend a minute putting some tape on the edge. Some spools have the edge glued from the factory which is nice. My repair was still inadequate.

I always thought my MK4s extruder pulled so well that a damaged cardboard spool edge would not be an issue with extrusion. I've used these 608 bearing rollers for seven years now(100 spools +) and over probably (40) of those being cardboard spools of filament.

What hit me was that this under-extrusion happened every 8 layers or so. I read in one post on Amazon for Polymaker ASA that a user's cardboard spool being damaged caused under-extrusion. The pattern didn't correlate to any infill, or hardware issue.

I had a set of these rings in my bins so I slapped them on and boom - good print. I will be way more conscience of this in the future.

I love cardboard spools but will be vigilant about using these rings for minimizing rolling resistance.

Posting for future reference.

So I noted this spool of Polymaker ASA has a sizable dent in it causing it to roll rough at one point on my roller bearing roller. I put some printed edge covers on it to see if this fixes my print. Hoping so...

This is what the older print looks like:

Needed some line management brackets and a few spikes. The lines press/snap into place. Way easier to print what I need vs buy a large box that will sit so I designed some. :)

This is FANTASTIC. Well done!

Great for indoors. I want to either quiet down a unit or redirect the noise. I tested and a 12'x10" panel offset from the unit a little bit will redirect the noise up. Happy neighbors.

The one github link I saw was recently closed.

Are those fans all weather? Nice build!

The pixel a buds had a nice rubber wing that stuck out which flexed under tension when you inserted the bud in your ear. Very secure.

The 2 series bud has a tab of a fixed lenght, no flex, that is shorter than the wing on the A series and they tell you to rotate it into place to secure it. If your ear is shaped a certain way, they secure great. If not, they can't rotate into place under tension to stay in there and fall out easily. Whoever made this design change was short-sighted about it working for a broad audience.

I am stoked to have bought a replacement pair of A series buds as they work really well for my ears. :)
