SAMLA Drybox for Filamentalist V3

SAMLA Drybox housing Filamentalist Rewinders:

Mounting for Filamentalist Rewinders inside of the SAMLA 22L Container as a Drybox.

Filamentalist V3 added! (Pictures Pending)
While testing V3 I found an issue that was always causing problems (even on the F1 version) that was amplified with my initial V3 design. Since SAMLA has feet on the bottom corners of the container it allows the bottom to flex and sag due to the weight. When fully loaded there was enough flex to allow the wheels to rub against each other and hinder proper rewinding.
This was less noticeable on F1 due to the rewinder feet being at the edges of the container but it was always present and would harm reliability. Due to this with my redesign for V3 I've decided on the following design constraints:

A) My main design will be limited to 3 units. This increases the distance between them so flexing is no longer an issue but this also allows for the wider spools.
B) I will keep the main body of Filamentalist unmodified as the new mount will use the 2020 center body.
C) Keeping it fully printable within a smaller bed and reusing as much of the Filamentalist BOM as possible.

4 units might be possible if using a 2020 extrusion as it should limit the flex between units, unfortunately I do not have any spare extrusions to test this myself. In the future I can upload mounts for 4 units but it will be untested by me.
 

Filamentalist F1 0.2v
This mod was removed from the Filamentalist Github as it was found to be problematic, not just with my use but in other situations as well. I am keeping the files here for preservation and archived similar to Version 1.0 in case anyone is currently using them but I will not be supporting issues with them in the future. If you're starting fresh you only need the newest version! I'd highly advise against using the F1 versions even if you want 4 units.

Sized for 68mm wide spools, fitment is tight, only 1mm between the wheels. Tested with Sunlu and Polymaker Spools.
 

Version 3 Desiccant Container
I would like to refine this in the future. I slapped something together quickly that was easy to print and used as little filament as possible while also containing the absolute maximum amount of desiccant I could fit. This works well enough but without a lid it is easy to spill it everywhere.

What to print:

Everything is sorted into folders as needed. The newest version is 3.1 and is all that is needed for a new build. Note the quantity in file names for when one part is needed multiple times.

Print everything in Version 3.1 Container for each container*.
(*you don't need multiple drill guides for more containers)

Print everything in Version 3.1 Original Refined for each rewinder*.
(*if you aren't reusing original parts)
(*based on the 608 bearing version)

If you are reusing your rewinders you will not require anything within the Version 3.1 Original Refined folder but there are some useful extras in there. Most of the parts were cleaned up in some way, adding chamfers, smoothing sharp edges and fixing sizing where I thought it was needed. I recommend using these over the original files if you're starting from scratch.
Chassis Beam Center Spacer is designed to work best with the printed center beam, though not required as the original 2020_Mnt_Center_Spacer_[option] and Chassis_Cntr_Spacer will work.
Standalone Center Mount - Front is to add some rigidity to the front of the assembly when using the center mounts and the REAR/BOTTOM LOAD CONFIGURATION.

Compatible Spools:

The maximum spool size is ~72mm x ~200mm. The official Filamentalist docs say 74mm but I found this might cause the sides of the spool to rub on a rim and slip out. You also might be able to go slightly over 200mm in diameter but you'll start rubbing on the lid, keep in mind your lid may sag.

Tested with SUNLU (old solid and new Reusable v3 spools) and Polymaker Cardboard spools.

Please feel free to give any feedback on spools from other manufacturers so other users will know ahead of time what will and won't work!

Assembly:

While many of the steps will match the original build manual there will be some differences outlined bellow if you are using the refined parts. Build according to the instruction for the 2020 mount on page 21 in the Rear Load Orientation.

Standalone Center Mount - Front will be added when assembling the two halves. It is not required but I wanted to increase the stability to the front when using a center mount option.

Idler Rollers were changed to fit M3 x 8mm FHCS as well as M3 x 12mm. The face of the wheel no longer requires breaking away bridge supports.

Shout-out:

I used the Center Roller by theminjus with the V1 and V2 files which lets you install the one-way bearing without tools. I found the original roller too tight and I worried about damaging my bearing. I slightly modified it to make it print better, similar to the “cleaned” F1 parts. I did not find this required anymore with V3.

I recently changed to a different hydrometer mount since this mod uses up pretty much all of the space at the base. I am now using the magnetic mount from thrutheframe and they fit great! If you need a hydrometer I highly recommend this mount.
