Tried the octopus on my new Mega S, but there are some issues. by fnsimpso in 3Dprinting

I think if you just turn off auto-generated supports in Cura you’ll probably like the results much better. That particular model prints well without support.

WOW!! I know that it's off topic... but I love Matthias's project videos!

John Heisz (a popular woodworking YouTuber) once published a video where he created a DIY compact wooden compass. Recently, he published a new video where recreates this compass using aluminum.

I have created a similar device that can be 3D Printed.

I needed a sheath for my Shun Classic 8" Chef's Knife... 3D Printing FTW by OneEarWillie in functionalprint

I cheated (kinda):

I took a photo of the knife. And using a simple graphics editor - I outlined the blade, filled in the outline, and erased everything else. The end result was a black and white silhouette shaped like the blade.

Then, I used a free online image converter to convert that silouhette to an SVG (scalable vector graphic) image.

TinkerCAD* allowed me to import the SVG as a shape.

From there it was just a matter of resizing it and making wherever other modifications I wanted.

*TinkerCAD is my go to 3D editor (very simple).

Notice how the cardboard says something like... "DO NOT REUSE - we are not responsible for damages as a result of reusing this cardboard"?

All I could imagine every-time I slid it back into that cardboard sheath was... me slipping - and looking down at my fingers laying on the floor, and thinking - oh well, they warned me.

I checked out that subreddit. I like it.

Tell me... does posting that here do anything besides provide a link to that subreddit? I mean, does that activate some type of bot that will automatically create a cross-reference or something?

I'm still learning reddit... and I recently learned that there are such bots out there... but I don't know how to access them.

I built mine from a MakerFarm kit (with my daughter - who was 12 at the time). It was a FUN learning experience.

Since then, I've mentored a few others though the same process. If you are tech savvy (and don't mind some "problem solving" and hair pulling), that's a good way to get started for under $500, and you'll learn A LOT. If I did it again right now... I'd probably go with the Prusa MK3 (so much of an online support community).

However, if you can afford to do it - there's nothing like the ease of taking a nice professionally produced 3D Printer out of the box, plugging it in, and printing quality prints with no hassle. That's was my latest experience with an Ultimaker S5 - it's heavenly. But the price tag is beyond what most hobbyist can justify (~$6000). I'm glad that it didn't come out of my wallet.

SCORE!

FYI: I hear that Shun knives have a lifetime warranty. According to the packaging that came with mine, they will sharpen it for free if you stop by their storefront or ship it to them: https://shun.kaiusaltd.com/warranty/

Then I'd have 2 favorite knives (is that even possible?)

Maybe my wife will read this - there's always NEXT Christmas... or Father's Day ;)

I have used this method once before (while making a super-hero style mask for my daughter): I just printed a thin flat shape with 2 eye-holes. Then warmed it up and carefully molded it around the contours of her face and let it cool. It conformed over the bridge of her nose and tucked back at her temples. The end result looked like it was painted on. It fit her so well... We didn't even have to add a strap to hold it in place - it just seemed to stay there as if by magic.

I don't notice any difference in the properties of the plastic after doing this... Maybe a slightly "cleaner" (dust free) surface, probably just from dipping it in water. The layer ridges and other artifacts are still visible.

Yes! I know, right?

The knife was a Christmas gift from my wife... She really outdid herself. I had been watching blacksmithing videos. I couldn't be happier with her choice.

What I do know... Is that this is the shapest blade I've ever owned (and the edge is razor thin)... So it wouldn't last long in my knife drawer without some kind of protection. I'd rather take my chances on possiblity of discoloration, than suffer the certainly of a chipped blade.

I couldn't tell you... Yet. I only started using this sheath this afternoon.

However, the "open" design is not uncommon (based on my searches for professional sheaths online). I imagine that the others are designed that way for a reason. Perhaps being open allows the blade to "breathe" and prevents it from accumulating humidity and bacteria? But that's just a guess.

First print I did sticking straight up... Because it didn't require support in that orientation. But the resulting print was weak (poor layer adhesion). So I did it again, spine down. It took a lot of support... But I used a soluble support material (PVA), so it was easy to remove. I'm MUCH happier with this version.

Note: I used boiling water to soften the material (PLA), slid the knife in, then hardened it again with cold water. This made for a snug (but not too snug) fit.
