Hopefully its little  more than open the hole up further.

 

It was just that...  and one of these.

Haven't decided what I'm going to do about organizing the drybox, and buffer's yet tho...

I did a modified LACK V1.  My MMU is mounted on the top of the LACK, on the side.  Makes it easy to get to.  I have (an old) post about it here:  https://forum.prusa3d.com/forum/postid/138334/.   Planning to do the same for my MK39/MMU3 which I am currently upgrading.

I've a paver stone under my printer & squash ball mods.      I'm definitely going to have to mod something.    The cutout on the underside of the lid is too small, and the un-cutout parts of it are in the way.

Hopefully its little  more than open the hole up further.

My vague/nebulous goal is to mount the buffer on the lid, under an unoriginal dry box.  I've a number of feet of 3.0mm ID PTFE tubing on order to do so.

I developed a fork that allows loading the buffer without having to remove a buffer segment. To do this, simply push the fork from the front into the buffer element to be loaded and the filament can be pushed directly from the spool to the MMU unit.

This loading option also allows for simpler setups that were not possible before. For example, attaching the buffer next to or even above the printer (depending on the space available) within the enclosure or in a compartment underneath.

You can download the MMU loading fork here

To place the buffer on the ceiling, Chris Hill has developed a good solution that fits into the original Prusa Enclosure. You can find this here. 

I'm also using the IKEA Lack setup with MK3S+ and MMU3.

Originally I wanted to buy the MMU2 and build it in, but then the new MMU3 arrived and I wanted the latest, improved version for the MK3S+.I also recognised the problem with the filament buffer.

Both openings are now on one side - very unfavourable, because the new buffer can no longer be attached to the top of the Lack table as with the MMU2. The spool holders have also been modified, so the filament housings can no longer be used.

This is how I have managed so far: Filament buffer of the MMU3 built into the Lack table, next to the MK3S+ as shown by Prusa on the MMU3 pictures in the manual. Ok, but how do I get the filaments? The only way is to use a trick with an IKEA Billy shelf behind it. Here is a picture. It works, I have drilled new holes in the back of the Lack housing.

Unfortunately, printing large objects that take more than 2 hours will lead to "temperature error" messages with the MK3S+ unit. Everything else is working, I will ask Prusa Support to get rid of these error messages. The printer was used for months and very long prints without any error messages, they started right with the MMU3 usage.
