SMRT!

the square and hexagon example is exactly what i needed, thank you!

Wow, seriously?. All that just to avoid a support you can get rid of in seconds. You must really really hate supports!

If this technique doesn't have a name, then I'd call it an autobridge.

We just call it knock out holes.

What's the weird beeping?

Sounds like a slicer feature would be needed. Terrible to model this

I love this video. Very clear explanations and examples. Even *I* can do this, now.

I know this is an old thread, did you ever create a solution for vertical holes? That never print round lol.

How are you? How did you calibrate 2 printer heads.

Support haters unite! Very clever, thanks for sharing.

great video! PRUSA designs their parts on the XL (in 2023!!) and others with a square step inside but not with the 2 step. It eliminates most of the issue but not perfect. Yours is cleaner but leaves the head with a bit more air under it?... Really nice! Thanks.

super useful! thank you

Thanks for this, giving this a go right now. One thing to note is that I had to change my Top/Bottom Line Directions to [0, 90] in Cura for the layer lines to bridge correctly. Otherwise they wanted to bridge at 45º to the square holes. Edit: Worked like a charm, thanks again.

😮😮😮 awesome

cool stuff! thanks for sharing! found your video because Zack Freedman mentioned it in his latest video (or rather he mentioned that Kennetek implemented your idea and he linked to your video on his gridfinity openscad github repository)

What a AWESOME hack! Would love to see this as a feature in Cura that you can activate if the bottom of the hole you are making is not a critical dimension. Thanks alot! :)

I was looking online and there were alot of bad reviews for adafruit, but did you get all of your parts from adafruit, and if so, how would you rate it overall? if not, where did you get the pieces from?

How do you not end up with zero thickness geometry if you cut like this?

Hey there I had a question, these days I have been working on a project like that on paper. Theoretically for a person to get a 8bitdoo controller and a Bluetooth speaker how would a person get these things powered via a single battery? Because at this point I'm bashing my head into a wall all because I'm trying to do something with a radxa zero board instead of a Raspberry pi board. From what I'm seeing the gpio for the pi and radxa zero are not the same and thus makes it incompatible with hats that would otherwise fit a pi. At this point I'm thinking I need to gut a controller and speaker and just connect them via Bluetooth and just worry about connecting when the thing turns on. And just because I want to make myself suffer I'm trying to do this in the space confines of a GameBoy Advanced SP. What do you think?

Thanks for this video, I've come back to it a handful of times every time I need a reminder on the order of operations and just wanted to leave a thank you note!

Wow. 1300 x drill, insert, (4 x solder), glue, screw, watch, more steps... if all goes right the first time. Try the linux 'bb' code...

I was wondering why the prusa printer parts had weird screw holes. This explains it.

Thank you for shooting this. I was there and regret not shooting video.

Tetris...!!!

legend mate. thanks !

Excellent. I did a slight modification of using lines so that there is no cut on the outer wall, but concept identical. For larger holes, one might need additional steps to allow the arcs to be printed.

Very informative. Thanks!

Can you use the custom pcb from this vid for a raspberry pi 4?

Great tip, I was curious so I tried it with an LCD resin print and it worked fine (at least with 4.5 mm holes). I've found overhangs are hit and miss on resin printing. Nice to know if I publish my part it should print well regardless of whether FDM or resin printing is used.

FWIW, here is another article from six years ago on basically the same thing: hydraraptor.blogspot.com/2014/03/buried-nuts-and-hanging-holes.html

Useful for nut holes! But sadly it makes my already slow and complicated designs even more complicated and slow! Still awesome tho

Clever trick. I was hoping it would be a trick to print vertical holes, but cool all the same.

Using bridging to avoid supports. Brilliant! Thank you for sharing!

This is great. I have a situation like this inside of a a thing where water should flow and neither supports or sacrificial layer is a good solution. Have used this to good effect. But step two is to make it work with a chamfered bottom edge. Chamfer is important for water flow.

This is great. Thanks. Can't wait to give it a try.

Which software are you using for gcode ? I could not find any information about this on your website.

Great tip! Thx for posting.

Thanks for that, really helpful

This should be fairly straight forward to implement as a slicer modifier, similar to Cura's "Make overhang printable". Maybe you could even do thinner layers specifically for these adjusted bridges, similar to how support can print in thicker layers. I guess the modifier would be something like "reduce horisontal overhangs with bridges".

...or you could just make one layer that is solid, then take a drill bit and clean the hole up, would take a lot less time than all that extra modelling work in Fusion...

set opacity to <100% to see inside in Fusion360

Can you provide the link to the Y axis motor you purchased from Amazon? And the sheet steel? Thanks... Great video!

Идеально для тетриса.

just go to woodprix instructions if you'd like to make it yourself.

Making this now. Sadly doubt it will function. Wood seems warped, pegs barely fit or don't fit at all, Main axle isn't straight because the hole itself is drilled at a slight angle. Just a shit show all around.

would you be so kind and put the spool holder file in your set? I checked few times on your video and haven't seen it.. thanks for updating the link for the FB group

I'd love to know what material that was which produces the negative effect? Also, that darth vader image is awesome!

Looks awesome, can't wait to see more! Have any video of it running?
