MultiBoard connections

[ShadowP68]

I am trying to figure out how to connect multiboards to the sides of the racks. so far I have figured out that every 3 mulitboard section will line up with 5 sections of the rack spacing. the spacing will equal 75 mm. so I think it is possible.

It looks like a 8 or 9 grid for the multiboard will fit on the vertical bars using the 14 length horizontal bar side. It am thinking a single and double connection for at joint locations.

I still need to collect more information on measurements but just thought I would get this idea out there.

got started with some files, got 2 different single ones and 2 double ones to attach 2 mulitboards together. you will want to mirror the double ones have one on either sides.

your thoughts to see if I am close for this to work.

sorry for my late answer.
I somehow must have deactivated the notifications on discussions. strange.

However: Nice work there.
What you definitely want to add is a counter wall on the HomeRacker side to enclose a support like a u-shape.
Otherwise you'd put a lot of weight on the lock-pins which aren't made for holding weight directly along their insertion direction but rather perpendicular to it.
does that make sense?

I was thinking about that shouldn't take much to add that.
I am just learning fusion so it is taking awhile. would like figure out how to do parametric to be able to change the connection length for different size multiboards.

Added the counterwall.

great.
you're almost there.
The measurements of the lockpin holes aren't quite right (referring to homeracker to multiboard double offset). Specifically:

• The distance between lock pin holes needs to be 15mm. yours is 10mm
• Not as important but to be consistent: The width of your homeracker mount is 26mm. If you intend 2 units, it should be 30mm
• On the inner width of the connector (see screenshot): it should add 0.2mm of tolerance, otherwise you'll have a hard time fitting it onto a support

* The "height" however can be 15mm straight to have flush finish (see screenshot) * You might want to add 0.8mm of chamfering on the outside of the lockpin holes. Makes fitting easier.

Apart from the first point, nothing majorly flawed. So: Well done for your first project! :-D

The offset one is when it is used where a multiboard is offset from the homeracker holes, and that would be 5mm offset oneway or the other, that is why it is only 10mm wide. I will get the .2mm tolorance added.

[ShadowP68]

as for the width being 26 mm instead of 30, I was having some issues with the holes lining up because it was too tight up against the homeracker brackets so I took 2mm off from each side.

[ShadowP68]

oh, the offset one would only be using one pin.

I think I got them all figured out. The single ones are for connection the multiboard to the Homeracker posts. The double one it to attach two mulitboard together and to connect to the Homeracker posts. The offset ones are set for the multiboard panel that doesn't line up with the typical 15 mm spacing. my calculations came up with them being 5mm off with the multiboard spacing depending on which panel you are connecting to, hope that makes since.

Here is the latest stl files.

and here is a 3MF file

my next step is to figure out what size mulitboards to use. I know a 9 panel wide will fit the drying rack size homeracker. and I think an 8 high panel might be the one that fits with the different heights. maybe with a 4 high if needed. My calculations came up with that the first and then the 4th panel would line up with the 15 mm spacing but the second and third are 5 mm off.

when printing you will need to clone the doubles and mirror it to get the ones needed. the 3mf file already has a complete set.
