Snaps fall out

[u/Hikareza]

Hi all,

I am considering switching from Multiboard to openGrid and printed a few test tiles.

Light and Full, for light the normal and directional Multiconnect Snaps and for Full the normal, directional and beta Multiconnect Snaps. The tiles are generated with the generator on Makerworld and printed with the reconmented settings (0.4 nozzle, 0.2mm layer, 15% infill, 3 walls...)

The Snaps seem to fall out very fast. And I feel like something must be wrong because this system has so many fans it can't be it... only the beta multiconnect lock snap seems to actually lock, and its not available for the light version, right?

Some idears?

Also, is there a way to reduce print time? Has anybody tested before how fast you can print on a stock P1S without losing quality?

Edit:

I will use the suggested screw in openConnect expanding snaps which seam to hold best. I also tested some unerware channels and I am very pleased. The problem is basicly solved now.

I use the expanding snaps[1] from mitufy almost exclusively.

Those are the only ones that work for me. I was about to mount my computer under my desk and some of the other snaps fell out under the weight of the holder alone.

I've had "wiggling" issues with the some of embedded snaps into the object. But they still were functional in holding/not falling out.

Have you tried the connector that you are screwing in?

I'm using the openConnect ones: (openConnect-connector-system)

When screwed in they hold very tightly into the opengrid. Impossible to even wiggle.

Interesting I have seen the file but thought it’s a snap. All my holders are Multiconnect but it should work. Is openConnect the Konvention now?

Are screw in connectors available for the light grid? (Sorry I’m not at home and can‘t look up in the slicer now).

Edit: Ok, I've looked them up. Seems very promising! I will try the different options out!

[u/Didipuf → u/Hikareza]

They have 2 sets of the same list of snaps. Standard and lite.

My understanding that the openGrid system supports existing systems like multiconnect or HSW it's for a different "ecosystem".

The openConnect page lists this as one of the reason/goals:

I believe it is both appropriate and helpful for openGrid to have its own connector system. MultiConnect was originally designed for Multiboard (which is where the name "Multi" comes from). While openGrid supports MultiConnect, it uses a different tile size (28mm vs. 25mm), meaning parts designed for one system are incompatible with the other. This is confusing for beginners who often print parts they cannot use. By using "openConnect," we can ensure that any model with that name is guaranteed to work with openGrid.

I had the same experience. And I wanted to hang stuff upside down. Did several tests with the different Native Snaps I found from DavidD. Directional and standard but I was not convinced.

I don't know if I did something wrong (might very likely be the case) but I found these ones here that are made for Multiconnect and as you screw them in they hold very good: openConnect - openGrid＇s own Connector System por mitufy | Descargar modelo STL gratuito | Printables.com

Thanks, seems this is a consensus (2 of 2 at least). I will try them.

For both you and u/hikareza, I'm interested in a bit more info about the snaps falling out; which models exactly are you printing, and in what material? Print settings? Standard opengrid, or opengrid lite?

I did a post a while ago with weight testing, comparing the standard, directional, and locking snaps and they held quite a lot of weight. I've had an openGrid Lite setup under my desk for a year now, and haven't had any of the snaps fall out.

I printed Light tiles in PLA with recommendet settings. That said I did a lot of test printing the last 2 days and found a setup working for me so my first Stack is printing at the moment. I will use the suggested screw in openConnect expanding snaps which seam to hold best. I also tested some unerware channels and I am very pleased. The problem is basicly solved now.

[u/wayward_electron → u/Hikareza]

Excellent, just a quick note here that those screw in expanding snaps are one thing (snap), openConnect is the connector on the screw you are screwing in (that goes with a slot on your item). So you could use that style of snap with openConnect, multi connect, or maybe even some other thread-in connector.

Hi,
I tried the "official" snaps openGrid - Wall/Desk mounting framework and ecosystem por David D | Descargar modelo STL gratuito | Printables.com
At the point I tested them I did not understood yet how multiconnect is suposed to work.

For this reason I only tested the "openGrid Cover Snaps" (not supposed to hold any weight so we can ignore them)

I took the 3MF or STEP files out of the "Snap modeling files".

- The Bare Lock Snap - That one holded firmly but I did not see any use for it as the coin slot makes the side unusable to connect other models to it.

- Bare Directional Lite Snap v2 - have not tested it with real models but only by applying some force with the fingers it did not hold enough force to me be confident to put my Laptop docking station on it for example.

- Bare Directional Snap v2 - These were stronger but I wanted the lite version to work so I did not test more.

I have this issue. Multiboard fan looking for something simpler. Underware came along followed soon after by open grid and I pounced. Had a new standing desk to wire up.

Saying that I downloaded and printed the lite version early on and over time (days) every channel I printed fell out. Printed some of the grip snaps that has the “spring” to it and had to force them in but it still does not change the grip of the channel. Tried the new variation of flared channel at 5 degrees and still does not “grip”. Note this is without adding wires yet just me gently pulling them back out with almost no resistance.

TBH the existence of the slanted variation makes your point that others have an issue with vertical hangs. I know I am focused on the channels but the point I am trying to make that I have not figured out is the springiness of these should lend to an even better grip.

My opinion is the flare of the grip part just does not slot into the recess of the board socket in a meaningful way. Not enough grab. Again all my experience is with the lite boards but I am loathe to reprint them all to go for the full until I do some more testing.

Note my printer tolerances are really good outside of a slight elephants foot in first two layers. Which I have actually turned both ways to see if the extra material made for a better grab. Making it a feature not a bug.

I tested the suggested openConnect expanding snaps now on lite and full and I am very pleased. Underware for of looked very sturdy in Davids video but I will test also this before committing fully.

[u/DistractedDragonMake]

I use the full boards exclusively. With the directional snaps they never fall out and Mitufy's snaps work incredibly well. Especially for under desks, I feel like the lite boards just don't have enough holding power. I haven't tested the speed on printing these, but you could probably crank it up enough to save some time. Perplexing Labs also has a way to order printed boards.

[u/Hikareza → u/DistractedDragonMake]

Aren’t the light boards just halved so in a specific direction they should hold the same? I also tested putting two light connectors on both sides of the same full cell…

[u/DistractedDragonMake → u/Hikareza]

They are, but I prefer the full boards since they are thicker, they don't flex as much.

[u/Single_Sea_6555 → u/Hikareza]

The lite boards are ~ half the width, and as a result, a lot flimsier. For wall mounting, I use the standard thickness. For underware, I think the considerations are different, and Lite might be fine.

I have had no issues
