Custom Dry Box / Work Bench

This has taken a while to design/source/build but I'm pretty pleased with how it's turned out.

It's a 4040 extrusion frame with Polycarbonate side panels/sliding doors, and some bathroom worktop/counter top.

Dimensions: Frame is 80cm tall, 66cm wide & 60cm deep. Worktop adds another 3cm thickness to the top and 3cm overlap on the front, plus 1cm each side.

There are a total of 36 filament feeder holes to allow fast swapping between colours/materials without having to open the doors. Hopefully I can keep the often over 60% humidity out (I live in the south of the UK).

Just using desiccant for drying and a small very lower power heater fan. There are 3 lines of filament on the bottom and 2 more hanging from the top, giving about 2.5m of rail space for filament reals to rest on. The rails are covered with Teflon tape which seems to provide a good low friction surface for the reals to spin on.

To control the fan heater and lighting, there is a ZigBee dual relay switch and then a Ikea ZigBee two button remote on the top right.

I set up a generic Hygrostat control in Home Assistant that uses the humidity values sent back by the ZigBee sensor & temp display, you can side on the inside left. There is also a backup Bluetooth humidity sensor at the back of the cabinet. 

Prusa XL5H sitting on top of custom dry box desk, filled with filament.

Workbench with built in filament dry box.

All the brackets (PLA for stiffness, everything else is PETG), upper rail hangers, handles, feet, filament feeders are my own design. At some point I'll get around to posting them on Printables.

Feel free to ask questions and give feedback on what I should have done differently 🙂

Oh, I guess my pictures didn't make it through the 'system'. And the formatting has gone - sigh.

RE: Custom Dry Box / Work Bench

your pictures didn't make it, because there was formatting information preceding the image

I Don't know how it got there, but removing it revealed your images

My Pleasure Anthony. 

You mentioned formatting...

Formatting actively blocked your pictures

Did you actually add any formatting details. if so, can you tell me where and how you did it

I have seen a number of instants where formatting has caused an issue like this. but so far, I don't know what causes it. and when I ask my Prusa contacts to look at the issue, I Don't get satisfactory responses.

RE:

The original text had paragraphs separating, what is now, a fairly unreadable single block of text. Strangely the text after the first picture seems to have kept the paragraphs correctly. 

I suspect the issue arose because I copied out the text into another editor where I fixed a few typos and grammar issues, before pasting it back into the post. I used Gmail to keep the draft in.

I learnt a long time ago to make a backup of any long posts before pressing the submit button 😉

RE: Custom Dry Box / Work Bench

in the early days I struggled with posts. wonder if that improved when i became a moderator, or when the forum platform changed...

your pictures show now,

if you have a recurrence of disappearing pictures, you will soon be able to DM me... or report the post and ask the moderators to make the pictures visible. 

regards Joan

Very nice setup, Antfurn!

What are the colored circles/disks used for in your last picture?

Thanks BigToeDaddyO,

They are for feeding the filament out of and up into the side XL filament sensors. There are 18 on each side and have PTFE tube connectors on each one. In the 2nd pic above you can see one on the right hand side with a short length of tube inserted. I made them so that can swivel to help reduce any tight angles on the filament path.

Here are a couple more pics of prototypes I printed:

Doh!

I just did not zoom in (thought they were decorative).

Apologies for asking the obvious…

Thanks for answering so completely…
And, as I said before, very nice!
