Anyone know of any pre-fab kits where I can stack 2 AMS units one above the other that will have enough clearance to open the lid on the bottom unit?
People rave about certain IKEA stuff but I have not had a need. There is an IKEA about 1.5 hours from me in Charlotte, NC.
Alternatively, can building something on gliding rails similar to a drawer where I can pull it out to open (and not have it tip over) while being beefy enough not to induce shake driven imperfections in a print.
I asked the original question and started Google searching and found this.
For those who are unaware, a good Diablo miter saw blade for aluminum will cut 2020 like a hot knife through butter.
I have parts on order to make the stand in this link.
Uses 2020 extrusion materials and meets my criteria.
Not pre-fab but pluses far outweigh the minuses and by using that 2020 extrusion it makes it extremely modular.
My AMS 2 arrived a few hours ago and I was expecting…I’m not sure. The advertisement literature talks about the “Airtight enclosure” but looks like an old school enclosure lid with maybe an improved O-ring around the perimeter.
Does have a dedicated air intake and outlet.
They have done away with the dessicant holders in the bottom cover. Vent holes still there but no lid to be removed.
Still working rack options in my brain right now. Once I saw how easy it is to cut the extrusion beams that really opened up my options.
I picked up this stackable shelf at Walmart for about $26: It’s like a custom fit for the AMS. The lids will open to about straight up, and the bottom of the shelf above even holds it open. If you want to open it further you have to shift the AMS a little bit.
I use the Home Depot Trinity baker’s rack shelf at 36" x 14".
I actually use two that I put together to support the 4 AMS, two Sovol SH02, two PolyDryer and a bunch of cereal boxes.
A single rack gives you three shelves that you can space enough to open the AMS units.
1 AMS and one Sovol can sit on the same shelf but the PTFE tubes on the top need more space.
I tried to add a picture, but it won’t let me add pictures.
I ended up going with this from Amazon. Many of the prefab shelves didn’t allow the lid to open fully. The shelves are adjustable in height, so it worked perfectly!
I could have built or printed one, but didn’t want to wait.
The problem I have with ready-made solutions is that they tend to have too much height and too much width for each shelf.
I saw some examples of where an individual re-purposed a set of wide hanging file folder cabinets to put AMS’s in that I thought was very clever.
The footprint dimensions of an AMS 2 Pro and a regular AMS for that matter are not very tall at 224mm / 10" tall with some added height caused by the drawer glides mounted on each side.
Additionally, I have an adjustable worktop that raises and lowers to allow me to raise and lower the complete rack to a good working level.
There is a model file one can print the parts to hold the AMS from but I am tweaking the rear part (blue) that in it’s original version is too narrow for the cables to fit in their sockets. The one in the picture is my first tweak and you can see it is still a touch too small but V3 is currently printing.
Shelf Closed
Did you scroll back and look at some of my pictures as I was designing project?
There are differences between an OG AMS and an AMS 2 Pro which I had to edit the tray back for the different plug setup. The blue handled tray is the AMS 2 Pro and the 6-pin cables hit the tray back but just the AMS 2, old AMS work fine as is.
My motivation to make the shelves was this article. Weekend Project - Aluminum 2020 Extrusion Shelf for the Bambu Labs AMS
The 3d Printed AMS Trays are these that are on Maker World. The tray image in the Doscher article are slightly different than what is on Maker World. AMS Tray for stacking
The glides I used were bought at a local Lowes Hardware and if you are not in the US I suspect a large home remodeling/repair store will have the appropriate Glides. I used these 16" Reliabilt locking glides.
The trays attach to the glides and the models have holes for heat-sets built in. I used 16" glides because they have enough screw locations along the glide that you can match the heat-sets to the trays without having to break out the drill. 14" glides would make a more compact rack but it would be very tippy and you would need to drill holes in the glides to match the heat-set locations or modify the model to reposition the heat-set holes.
To bolt/screw everything together I just used standard 2020 profile and drop-in T-Slot nuts. Socket head bolts will not work to bolt the glides to the 2020 profile. I found these, on Amazon, that worked well. The typical socket head screw head is too tall and drags on the glides. M4-0.7 x 8mm Flanged Button Head Socket Cap Screws
If you want, I can pull out a drawer and zoom in on some of what I describe above. There are some other parts that need to be bought from Amazon but nothing exotic.
Additionally, the AMS 2 Pro, having a built in dryer, has an air intake vent and a damp air discharge vent. The Maker World model does not accommodate one of the vents, effectively blinding it over and killing the air dryer aspect. I had to edit that component to allow for air movement.
I’m not a fan of jigsaw’s, even good ones. Nearly impossible to cut a straight/90º angle.
If you don’t want to go all in with a miter saw you can get a small Harbor Freight chop saw for dirt cheap that can handle 2020 profile no problem.
The AMS has to pull out far enough to allow lid to stay open on it’s own. The footprint is about 17" deep and any less it becomes a significant tipping risk.
The AMS (obviously) can’t make contact with the adjacent AMS.
Staggering them doesn’t give you any benefit. It eats up workbench surface because the rack has to be deeper, front to back.
The reason I did what I did was because store bought shelves are either too wide, too tall (shelf to shelf), or both. The cheap option is to go to Wally World and buy a cheap plastic 3 - 5 shelf kit.
I wanted the smallest practical footprint possible. I mocked up staggering the AMS units, but staggering would have probably doubled the depth
The footprint of the AMS is what I worked off of.
Yes I did. I mocked it up before I cut the vertical 2020 profile to insure I had enough height to open the AMS covers on the lower two AMS units.
The drawer glides I sized to be able to pull the AMS drawer out so the lid would open fully.
If you do decide to make something similar and happen to have an AMS 2 Pro you will need to accommodate the air vent and discharge. The older AMS units do not have the vents and the rack drawer files were uploaded before the AMS 2 Pro model had been released.
The microwave shelf from Amazon looks interesting. I want to get my AMS 2 Pro off the top of my H2D printer and stack on top of my other AMS 2 Pro. I don’t want to spend days of printing 3D models to make a shelving unit. The video on Amazon makes this look very adjustable both in width and height.
Thanks for posting this.
FWIW the trays each of the AMS units sit in didn’t take days to print. 2020 extrusions and screws came from Amazon. Drawer glides came from Lowe’s Hardware.
Fixed shelves you have to still manhandle the AMS in and out of the shelf. I bought an AMS HT after I built the three level shelf and thinking about making a set of shelves for HT’s using one of the existing sides since I have some extra 2020 extrusion pieces already.
Whichever way you opt to go, if you make some sort of drawer setup be aware that the shelf is prone to tipping if you pull two drawers out at same time. An AMS with four full spools is heavy
