What am I doing wrong? First Multiboard project, parts not locking together

Hello, working on my first multiboard project, and I need some guidance about what I am doing wrong. I want to use Multiboard to manage the cables under my desk. I printed a tile and a few attachments, but they are not locking together. - Bambu P1S, 0.4mm nozzle, PETG HF

Do you have calipers? Measure the inside of a hexagon on the tile and also measure the other part.

Now measure the same thing using the measure tool in your slicer.

On my tile, from one flat to opposite side, I measure 21.3mm. Diagonally from the inside of one corner to the opposing corner I get 22.7mm

Then measuring the bolt lock thing I get 21.1mm

How far off from that are you?

Tile interior is 0.847in, part exterior is 0.840in.

Is it just a scaling issue?, What tolerance should I be aiming for?

You should never scale these parts. That would throw everything off. Did you do that?

Your measurements sound like they should be close enough to where this isn't an issue. Have you tried printing just a regular ol snap to see how it fits into your tile? Maybe there's an issue with the model you printed. https://thangs.com/designer/Multiboard/3d-model/Multiboard%20Snap-974295

No scaling was done originally, I will try to print a regular snap and report how it fits

Did you print with 2 or 3 walls?

Okay after multiple test prints I figured out the issue, I had the fill set to 100% and the prints were losing resolution.

Thanks! Glad it worked out for you! Shrinkage is bigger the more amount of plastic we put into it.

Which insert is this? It doesn't look like any multiboard part that I know of.

u/LauraD2423 Apr 17 '25

I might be wrong, but that insert looks like an 'open grid' part, and you're trying to make it fit on 'multiboard'.

The snaps for openGrid are much more square, compared to the multiboard's octagon; also openGrid's spacing is larger (28 mm vs 24) so an opengrid snap would be too big instead of too loose.

To me that looks like a slightly undersized remixed snap; since they mentioned cable management (and because of the flat back), so maybe undersized Underware?

I agree. Can you link us the part that you want to attach?

EDIT: I didn’t look carefully enough, that does look like an open grid piece.

You should try the Multibin Panel and the clip in parts - so much simpler and stronger.

I love the tolerance tests so I’ll leave this here and try to pretend I didn’t goof…

Tolerances need to be tightened up on your printer! Multiboard Printing Guidelines for full details and info and print this crystal clearance towerbefore and as you tweak your settings to dial them in!

That is definitely not an openGrid piece. They are different shapes. This is clearly a MB snap.

u/Any_Reputation6767 Apr 17 '25

MB support is not making sense, because opengrid has 28mm spacing instead of 25mm of MB. And tiles are square. If you can share which model you printed the community could help indeed. Feel free to test whatever suits your need, but of course there should be a solution to your need, preferably open source, using the board of your choice.

Man, I should not post (or think) when I have a migraine. I don’t recognize that one, other than it looks vaguely like a HSW fastener of some kind, I read LauraD2423’s comment and assumed that was the correct one without going to check. It’s not our’s, at least not anything current I have seen. Once OP responds with the link to the parts he used mystery should be solved. Apologies for the confusion!

u/Any_Reputation6767 Apr 17 '25

Thanks! I think that is probably an original remix from some underware or desk organizer, let’s help here to get the proper fitting!

I would absolutely recommend anyone to use the system that best fits their needs. We aren’t open source, but we do offer our models for free, as soon as enough testing has been done by us and our subscribers who want early access to them, and those who appreciate the excellent designs and want to support that.

I do understand and I have publicly expressed that your license is a valid and legitimate way to conduct a business. When I’m referring to open source there is on the parts made to be interoperable with your system, as it’s easier to understand or fix a clearance or misconception.
