I wanted a ikea lack enclosure that had filament fed into it via ptfe tubes coming out of dryboxes.
I really like a lot of things about the original prusa lack enclosure but wanted a few changes.
For example, my printer is on a muscle rack shelving unit bolted to the wall. It is much sturdier than a couple of lightweight lack tables stacked vertically so I don't need the bottom table as a stand.
The legs of the table are connected to the shelf with a steel plate on top for fire safety. I really don't like the idea of something that gets up to 500 degrees F sitting on top of particle board shelving so there is sheet metal construction glued above and below the printer god forbid that is needed.
Because the table isn't sitting on the mostly hollow lack table noise is reduced quite a lot which is great.
I used 3mm acrylic panels from tap plastics. The standard door knobs don't fit very tightly on this so I modified the file to fit tighter such that it doesn't even need glue. https://www.thingiverse.com/thing:3450802
I wanted the lcd panel outside the enclosure. This is a godsend being able to go through the menu without opening the doors. However I didn't want the ribbon cable interfering with the doors opening and closing so I cut through the sheet metal and shelf and ran the ribbon cable underneath. I created a grommet to protect the cable and clean up the look https://www.thingiverse.com/thing:3451403
Regarding the drybox.
The original design has filament sitting on spools entering the enclosure from above. This is great but doesn't allow for easy storage of filaments that you don't want exposed to humidity. I suppose that you could store filament in dryboxes or bags with dessicants and then add to a spool for each print and then remove after you are done, but lets be honest we are gonna leave the filament on the spool from time to time and eventually it will get ruined. A much better idea is to have a drybox that feeds directly to inside the enclosure via capped ptfe tubes so the only time the filament is exposed is when it is printing.
Inside of the box I have the same humidity sensors mentioned earlier but I needed a way to hold them inside the box so I could see the numbers easily. I created this design to mount the sensors. https://www.thingiverse.com/thing:3421484
They are the best filament clips I've ever used, slightly modified to better fit inside the enclosure. To start a print you remove the cap, pull down filament to the extruder and it pulls through the ptfe tube all the way to the drybox, then when you are done you just feed the filament back up and put the cap back on. The caps are printed in the color of each filament. I used petg for my petg and pla for my pla. The top of the enclosure doesn't get hot enough to reach the glass point of pla so this is fine.
Remember to come back and post what you've printed as Make.
It's good for the designer and the community (that means you)!
