With the short time line given for this product I think it will be required to use off the shelf materials to build it. Any custom sheet metal would likely push out the time line.
Here is the assembly i have of an enclosure with folding doors that uses off the shelf extrusions and hardware.
The rounded extrusion is not offered in a black anodized finish, only a clear anodized finish
i have updated the assembly to be stackable, hold two minis or 1 taz7, all black anodized extrusion and all off the shelf parts from tslots.
I have not been able to source a drawer yet. I will keep looking but i was thinking a cabinet with shelves may function better and will be easier to design for.
Once a repo is set up i will get this all pushed
Just FYI , due to this being off the shelf extrusion from Tslot, The extrusion is a 1 inch diameter extrusion and the assembly requires Imperial hardware.
Tslot does not offer an off the shelf metric extrusion. We could source a metric extrusion from Misumi but lead times will be much longer
Looks pretty good. I've always thought that adding a monitor, keyboard, and (optionally) a mouse onto a arm that comes off it makes it looks more industrial. I don't know if it's within scope for this product, but something like that would take it to the next level IMO. I'm thinking something like what our Tormach has, or this:

Brent MacKenzie at the Colorado Printing Project has one like this:
I (personally) have one set up like that. It needs to be more industrial though, it is a bit on the low budget side.
@eBeardslee I have checked both online and in the physical catalogs from Tslots with no luck for an off the shelf 45 degree extrusion.
Here is Tslots' online catalog:
@eBeardslee, well yes that could work but with an entirely different architecture. Also, that is pretty huge extrusion and it doesnt come in black anodized. Its about twice as thick as what the enclosure is currently designed with so it could be quite expensive. Also this makes it impossible to attach any tool hangers or any other mods to the outside of the enclosure.
I dont think we want to use 40mm extrusion for this enclosure. That is the stuff o-pod is built out of in the cluster
the current design uses 1 inch extrusions, the TS10-10 series, so 25.4mm. This is their most common and base extrusion. This has the most hardware and accessory options
The TAZ frame is made from 20mm extrusion.
I saw that the 20mm extrusion is now in the 2018 catalog. Previously this has not been off the shelf extrusion. But there is somewhat limited hardware for these
So we took a look and since we are not able to get corners in anodized black we will go with silver extrusions. Furthermore, we would like to minimize the amount of open slot faces on the exterior of the enclosure by incorporating parts like TS10-10 BISLOT AD for the corner extrusions.
This is the setup I've been running in my home office, it's been working really well for me. I think that swapping the material used for the side panels from the signboard to Alumalite or something similar would go a long way towards making it feel more premium. The source is here, it's licensed under CERN and CC-BY-SA so you guys are free to clone if you like any parts of it. Let me know if there's anything I can help with, the source is definitely not as organized or complete as I'd like it to be.
Another option to clean it up would be T-Slot rubber inserts:
Similar to what is put into the CR10's. This would also allow customers who want to hack at the enclosure to remove the seals and install whatever they would like.
@eBeardslee the more milling and stuff we do to these, the more likely we run into availability issues. Also im trying to keep the number of parts to a minimum. right now the handle extrusion is the same as the other tall extrusions in the door, just turned 90 degrees. If we mill/drill holes for the handle, now that splits into two separate extrusions which becomes a logistics/inventory nightmare
We'll need to get this cleared with @mcoronado but I would imagine we use the T-slot inserts in any open slots. And at some point it might just be better for us to do all black with inserts to have some consistency (vs some non-slotted combined with slotted w/ inserts that don't match the aluminum as well)
@eBeardslee i agree that that would be a better option. The black slot covers will match the anodized black extrusions pretty well, keeps the variations on hardware down, and allows the customer to hack/modify if they want. I am going to contact tslots and see what kind of lead times there would be for milling/drilling the holes for handles and hinges in the non slotted extrusion
@karrad there seems to be a bit of back and forth here. Is the spec in the NPI docs confirmed for this project? Right now the time line shows ~6 weeks from today for completed concept development. Depending on some of the milled and customization in the discussion above it could take that 6 weeks to get the initial prototype parts in. We'll get confirmation of the lead time for the customization in case it is feasible.
The slight tint on this enclosure looks good. It'll look really good with the led light strips
pic #68 in the Black Anodize category
Also, the caps on #35 look pretty good too for cleaning up the open face extrusions:
@mcoronado, yes there are connector links that fasten the enclosures together once stacked. I agree that a slight tint looks good for the clear panels
We can get closed face extrusions from TSLOTS as well. I would like to avoid introducing a second supplier for extrusions if possible. Any particular reason you want to do 80/20 rather than TSLOTS?
For our discussion: https://8020.net/catalog/category/view/s/shop/id/837/?cat=380&color=3
Tslots can provide non slotted extrusions in a black anodized finish in bulk orders. This will not add much to the lead times. In order quantities of ~1000 pieces this will be 3-5 weeks, 5k-10k pieces this will be 5-6 weeks. For clear anodized extrusions lead times are 3-4 weeks for quantities of 1000 and 5-6 weeks in 2000+ orders.
Looking at 8020's website it is about 3-4 weeks lead time on their extrusions with custom hole placement but there are no quantities specified. I have contacted a rep at 8020 to confirm these lead times.
I am also asking tslots about getting black anodized extrusions for prototypes (small quantities)
Min bulk order is about 800 pieces.
For small quantities of black anodized for the prototypes:
"We can do a small one time order but we can’t do it in house. I’ll have the send the cut and machined pieces to a third party and they will anodize them black. Lead time will be about 10 days from start to finish. Our third party anodizer uses a single stage dye black where ours is a 2 stage architectural finish. Just want you to be aware as the dye finish may fade in sunlight. I think it should be no problem for a prototype though. "
@tutley Would it be possible to get the holes drilled into non slotted extrusions for the handles and hinges? If it is not feasible in the time line and/or quantity requirements, would we be able to do this with a fixture and our drill press?
Reviewing with Eric and Hob, if we can get the non slotted faces on the external parts of the enclosure, it would address their concerns. The sample I brought back with the T-Slot cover would be great for the top connection bars (y direction) so customers could have the option for adding attachments if they choose.
@karrad it would depend on the location of the holes. I think any holes we drill after anodizing would be covered by hardware but if not you would see the bare aluminum from the drilled hole. We can confirm Monday if that would be a concern.
@tutley did T-slot give you a minimum requirement for production qty or is that the 1000 pieces?
@karrad We can get the holes drilled into non slotted extrusions for handles and hinges with a small increase in lead time.
Also, I agree that having the option to add attachments/mods will come in very handy.
@Steven They didnt give me a minimum production quantity, but gave me a number of 800 PCE min bulk order to get the non slotted stuff anodized in black
Double stacked, non slotted, black anodized.
I am going to start working on getting drawings for all the TSLOTS pieces so we can get it ordered and get a prototype together. Still need to nail down power/lighting/ etc
Has this been proposed yet? Filament cabinet on top, with vent holes into that chamber from the warm cabinet environment. Add cut outs for filament feeding directly from the filament cabinet, with or without ptfe feed tubes.
For the clear panels, would you like them to have a slight tint?
