Very nice, job.

What parts are you using to mount the PSU under the table? are there files available for those?

What is the thickness of the glass?


So, I thought it was time to build an enclosure for my Monoprice Maker Select V2. I also have a Prusa Mk3 coming in late July. So I go to Ikea and get a couple of tables, put one together, and.... it is not high enough. I put a Z extension on it a while back and that makes it too high by about 3/4”.

Then I see your tall version. I think this might be my solution. One question. What are the walls under the perimeter of the plexiglass. They look like printed walls to fill up the bottom space created by the higher feet. Is that correct. Looks like they are interlocking pieces?

my enclosure was not tall enough, I had to design these pieces to add some height without changing the plexi screens. if you use the tall feet, you shouldn,t need theses pieces

I notice from the pictures you have a part that's up a little ways from the bottom to keep the plexiglass aligned when the top section is removed. Do you have a link to that part? I think without it the plexiglass would be hard to align back on the lower section.

Thanks for the effort on this setup!

Question. Don't you have issues removing printed objects if you only have a door on the front? I sometimes need to go around all sides to get it to loosen from the build plate.

No, usually, the front access is sufficient. But sometiles when i need sole maintenance, I take the top part off so I have full access. I designed it so that the top part could be easily removed and placed back.

Looks like a great design! I only have a couple questions does the hole for the fans let the heat out? Because for printing ABS I would want it to keep the heat.

Hello, wawaChief!
Great design all around! I have a couple questions.
I was curious what the measurements are for the Spool holders in relation to the side and back of the table. i.e "4 inches from the back and 5 inches from the side, with a 5 inch spacing between the spool holder arms".
The measurements in mm or inches would be incredibly helpful. Does my question make sense? I basically want to know how far to space the spool arms from their inside straight edge, and the distances from the front and back to place each spool holder arm.
I really appreciate your help and reply! Again, this is an amazing design and build!

HI can you post the link to the lac web cam mount...

I would love that as well... it´s the green part, right?

I haven't looked at the other parts yet, but the 2" tall leg supports in the rear have a number of non-manifold surfaces interior to the part. They cause interior walls to print inside the body.

Sorry for that late reply, I also ran into that problem. However this can easily be fixed with netfabb free edition. Just import the stl file and auto repair them. I am currently printing them, after repairing everything looked nice in Simplify3D.

Love it! Looks awesome

Do you have issue with higher print far from the top hole (Pass filament)?

Yes occasionally. I saw this filament guide which could solve the problem. I haven't tested it yet.

Where did you buy the Plexiglass? In Australia it seems ridiculously expensive, four panels at this size would be over $120!

I'm curious about how your Pi is set up? What are you using it for?

Also, The corner pieces that have the tool holder and sd card holder are top pieces?

The Pi is running Octopi. It is very useful to remotely monitor your prints and stop them in case something goes wrong...
For the corner pieces, I'm not sure to see what you mean exactly.

I like the SD card holder corner, but it looks like (and described as) a top corner piece. I'm curious about the reason.

Also, How did you connect the bottom corner pieces on top of the bottom table since the center whole lines up with the hanger bolt connecting the leg to the table?

Ok I see. In fact I have no idea ! I took this part from this (see the link below) and I don't know why it has this particular shape, but I found it convenient to hold the plexi door so I kept it. I guess you should ask nothing_fr.

The bottom corner pieces are just screwed on the bottom table. I guess I got lucky the screw didn't collide with the bolt connecting the leg... You don't want to put a long screw in here. A short one does the job since the lack table is quite thin. Also, there is no pressure or force applied on this screw. It is meant to keep the corner piece in place so a small screw is enough.

First I would like to thank you for your great design.
I've design a 3mm filament pass version that I would like to share. @wawaChief: If you want, you can add it to your model.

For those who use 3mm filament, you can download the stl file here: https://drive.google.com/file/d/0B9KXRnbPFRPyeG5zeENXU3BqNUU/view?usp=sharing

Hope that can help.

Did you leave all the electronics, except for the LCD and PSU inside of the enclosure?

Yes. The temperature does not exceed 35°C inside the enclosure. I have a fan on the bottom table I can plug when needed and another for the air extraction. Even when printing ABS, the electronics doesn't get too hot.

Has anyone come up with a better way to secure the top table, when using the latest tall bottom plexi holders? I still want the top to be removable, but would like to have a little more security. With the original plexiholders the pyramid portion gave a little support to the sides of the top table which was nice.

Has anyone tried velcro?

I drilled a hole into the center bottom of each leg and installed a 3/8" dowel

No issues with the Rambo still in the enclosure and the heat?

with the air extraction outside, the temperature in the enclosure varies between 35°C in summer and 20°C (25°C with abs) in winter, and is quite stable. I have two fans : one for the air extraction outdoor and one on the bottom table I usually don't use, so there is no risk of overheating the rambo.

Hi, thanks for your effort and design. I happened to notice in the enclosure tour video you have vibration dampeners on the Z Axis frame. Can you link where you got them? thanks!

awesome, thanks!

Hi, I like the lcd enclosue is that a printable design too?

The Lcd enclosure is purse's. I didn't change a thing. I just customized a support to attach it with a hinge on the enclosure :

For the spool holder, did you print it standing up or on it's side? Any risk of it cracking/separating from the weight of the spool?

I printed it standing up. So far so good... It is quite resistant. I don't think the spool weight can break it : 2,5kg at most divided on the 2 holders. Not a big deal.

Well... I was thinking of using a longer rod and putting 4 spools on it. I wonder if it would hold up to that...


(Bonjour, il semble que vous soyez Français :) )
I saw a small error in the bunch of file. The Tall Bottom Left is the same than the Tall Bottom.

BTW, many thanks for this!!! Really appreciated.

Bonjour :)

Je ne suis pas sûr de voir l'erreur : Les 2 pieds de derrière sont identiques. Les deux pieds de devant sont spécifiques droite/gauche car il faut que la porte puisse se dégager. Il y a donc 3 fichiers qui à première vue m'ont l'air bons.
tall_support_plexi_lack_bottom_front_right / tall_support_plexi_lack_bottom_front_left et tall_support_plexi_lack_back_bottom_x2

looks good to me.

@wawaChief Well Done! This came out perfectly!

I'm using it with a Monoprice Maker Select. I appreciate the comments below, they were particularly helpful. For the next reader, here's some bits to know: this is a rundown from top to bottom of how my table is set up (I believe that's how wawaChief has it as well)

Top of Lack table
Double-sided screw
Top brackets
Lack Legs
(no screws or adhesive, the legs just rest on the tall parts)
"Tall" brackets
Bottom Table
(optional) Screw and Bottom Table Legs

Since the tools that came with my Monoprice Maker Select were different, I simply deleted the tool portions and added a flat area. I'll upload those shortly.

The only items I needed that weren't included by Ikea or printed were screws to attach the Tall Brackets to the lower table. I agree with wawaCheif's recommendation for a small screw if you have legs on the bottom table as well.

thnx for this review!

Just got my MK2. Printing your LACK table setup. What kind of light did you use? Also do you have the handle for the front of the plexiglass? Thanks

I found the handle here : http://www.thingiverse.com/thing:179261
For the light, it is a led ramp found in a local store. It is attached to the printer's frame with these :

awsome work, im looking for a enclosure for my prusa mk2 because im having insues with mantaining temperature for printing large abs with low warping. how does it hold the temperature ? could u show more images of all sides please

Here is a video showing the enclosure under every angle :

The room temperature is around 20°C and the enclosure is around 32°C with the air extractor fan running. I Don't plug the 12" fan on the bottom because I don't have to : the temperature seems fine to me with just the air extractor working.

I will post more photos and a video with the printer working tomorrow I think.

I don't print a lot of ABS so I can't really tell if it really helps for the warping issue. What I appreciate is the evacuation outdoor of the fumes. There is no more melted plastic smells in the room.

cool, im already printing the parts, will shape it as i see fit to help me with warping :), will be waiting for more pics.

Great. For the bottom feet, don't forget to print the tall ones, so that you have enough height between the tables.

hi again, how do u keep ur printer in place? or is it loose? what do u thing of this http://www.thingiverse.com/thing:237262

The printer is loose, but it doesn't move. I use dampers to reduce the noise :
You could glue or screw these dampers on the table.

I am a little confused on the tall sections.
is the table suppose to just be sitting on top of those?
am i maybe missing something? does the plexiglass stablize it enough? thanks!

The tall sections you see are something I add on my own enclosure because when I built it, I saw that it was not tall enough so I had to make that little hack to avoid buying new acrylic sheets. The top table is just sitting on this section and can be easily removed to access the printer.

If you build your enclosure I suggest you use the big feet to add 5 cm of height to the IKEA feet so that you have enough space in Z. In this case, you mesure the good height for your acrylic sheet and have no need of this additional section.

Although I appreciate your tall parts, why not adding cutted legs of your bottom LACK table? Is +5 cm enough? The usable LACK height is 40 cm, then you added anti-vibration feet... Wondering about correct filament path with high Z.
Which material did you use fort these parts? PLA?

I couldn't find it, what is that green piece added onto your webcam there?
Thanks for this build, my gf hates all the moving parts out in the open, is afraid the dog will one day get onto the workbench and get caught in it or something strange like that. I've seen other enclosures, some like this one, but this is the best implementation of it in my opinion.

Thank you. The webcam is a logitech C270. With this cam, it is impossible by default to adjust focus so I printed this http://www.thingiverse.com/thing:1406879 to allow focus adjustment.
In the pictures, the cam is inside the enclosure, maintained with this : http://www.thingiverse.com/thing:1334020, but I changed this setup : it was too close and I couldn't have a good focus. Now, the cam is outside the enclosure and I have a better view and focus. I have something like this http://www.thingiverse.com/thing:1199083, attached to the lower table to maintain the cam in place.

What did you use to hold bottom supports plexi to table? Glue, screws..?

Screws. There are holes in the center of the supports for the screws. Don't choose too long screws, you don't want them to mess with the screws on the other side for the lower table.

Thank you !!! ;-)

What size (lenght and high) are the acrylic sheets and did you get it airtight for printing ABS

I printed the eight pieces at the two sides of the 4 feet and assembled the tables. Then I measured the exact length and had the acrylic sheets cut to the exact dimension in the store. Doing so, the acrylic sheets fit perfectly into the frame and there is no gap. On the sides, I put some tape to improve tightness.

It is probably not perfectly airtight but I think it is quite enough, especially with the air evacuation outdoor. I can't smell anything when printing, specially with ABS.

Thank you, good idea :-)

What is the thickness of the acrylic sheets? Thank you!

It is 5mm thick.

Could you post a link to the Ikea table you are using, I can't seem to find it and would love to try this out.

This is just awesome !

Could you add some more pictures of it please ?

Thank you. I have added some pictures. Is there any other parts you want to see ?

HI wawaChief, i am impressed of your work. I ordered my MK2 3 Weeks ago and awaiting it any day. Right now i am plan my Enclosure for this printer. Then i'll print the most time with ABS.
Could you make a Video of your Enclosure when the printer is working? I mean a complete 360° View of this enclosure.
The most i am interested in is the Airsytem.

Thank you. Next object I print, I will make a video of the whole thing. You will have to wait a few days.
