Are there any custom 4-point bed trays? Will we ever get any?
After owning a Prusa MK3s for almost a month now I started noticing some bed wiggle.
I was wondering why Prusa3D does not offer a standalone 4 point bed tray?
From my perspective, I think it would actually help with making the bed assembly even more reliable.

Mine rattles noticeably when I do Hilbert patterns. I think it is the right hand single bearing being loose. Probably needs another turn on the u-Bolts but that appears to require a complete heat plate removal. Putting that off because it is printing so well.

You don't need to remove the bed. You can print a slotted spanner the correct height to get in or simply cut a bit of sheet metal to the correct face to face for the wee capture head nuts. They are not meant to be super tight so you don't need a highly tempered tool.

If you are going to remove the bed, print out some bearing holders before you do. Replace the u-bolt with something better.
The u-bolts are just a bad idea.

Thanks for the suggestion. I found this on Thingverse and it printed perfectly in PETG and was just the right length and thickness. Each Nylock got a quarter turn and the Hilbert pattern test will start shortly.

Is this the bearing mount you were thinking of?

Thanks for the suggestion.

I'm sure those are fine.
I use these since I'm using the Bear X-Axis and frame. You'd probably need the half upgrade, since I assume you've still got the Prusa frame.

Edit: I actually did print (and still use) the half upgrade when I upgraded the bearing last summer. Just make sure you use PETG and follow all the suggestions Gregoire notes on the page.
