This is a stand to store the Sunlu S4 on. I wanted something to keep my filament vacuum bags and vacuum pump I use to store my “freshly dried” filament in, all within the footprint of the S4. It has a main compartment and a smaller compartment. 

The main compartment can be used to store vacuum bags. I have modeled a large drawer that will fit in the main compartments opening, however I haven't figured out a good way to cut the model in half. Since it is bigger than my build plate, it will need to be printed in two pieces similar to the stand. Once I have figured it out, I will update this model with the files.

There are two options for the smaller drawer. Option one is an empty drawer. Option two has cutouts for the vacuum pump as well as bag clips that come with the filament vacuum bag kit I like. I have used a few different brand filament vacuum bags and pumps and really like this kit. Here is a non-affiliate link to the kit on amazon: https://a.co/d/hIQW0PD

When printing, print the two body pieces at the same time, standing them up on their backs as shown below. I will also be uploading a default printing profile for this. Printing it this way will cause the least amount of support to be needed while producing the best quality print overall. Every time I tried to print it laid on its bottom (the way it would naturally sit when being used) the “roof” above the support never printed nicely. It would be nice to be able to print it this way, because the filleted edges would look MUCH smoother but I cannot figure it out.

I printed the stand on my P1P converted to S using the .16mm Optimal @BBL X1C profile. I turned my aux fan off and turned cooling off for the first three layers. I enabled support using “normal” for the type and “Default” for the style. I used 15% gyroid infill with 3 wall loops.

I have printed the stand twice.  The first was printed using white Hatchbox PLA. The second I printed using Bambu Lab Black PLA-CF. For the regular PLA, I used my dialed in Hatchbox filament profile. For the PLA-CF, I used the Bambu Lab PLA-CF profile. They turned out different enough that I thought it worth mentioning.

The Hatchbox PLA printed great. It was closer to the actual model when it came to the fit down the seam of the two bodies. The model had a .2mm clearance cut along the path that I drew, and the PLA print had almost exactly a .2mm gap between the two sides once assembled. Assembly was extremely easy as the two side just slid right together almost no resistance. The seams were loose enough that I feel that some super glue along the seam, top and bottom, is necessary.

The PLA-CF printed beautifully as well. The only real difference is that the seams are pretty tight when assembling the two halves. I had to be patient and not force it too hard. It didn't take very long nor was it difficult, it just requires some patience. I am going to guess that this difference between the two is due to me using the default Bambu Lab PLA-CF profile vs the dialed in Hatchbox profile. Either way, it was still easy to put together. It was tight enough that I didn't feel it necessary to add any glue. It wasn't going to budge. Also, the PLA-CF filament is very rough and I tried to dust it with a rag. Some of the pictures you can definitely see the rag particles 

If anyone wants to make changes to these models and wants the project files, then please reach out. I modeled them in fusion 360 and can provide the project files. This is the first time I've modeled something not using tinkercad so there may be better ways choices during modeling.

Edit: There was a concern around the stand restricting airflow and raising the temps of the dryer.  I used an IR thermometer to take temperature readings in and out of the stand.  To start with, I removed the dryer from the stand and turned it on, set for PLA (130f), and for 2 hours before taking the baseline readings. All temperature measurements were done to the outside. I measured on top and on bottom. I measured the top because that was the hottest part and the bottom since that is closest part to the stand. The top measured at 110.4 in the hottest part and the bottom measured at 109.6. I then put the dryer in the stand and left it for another 2 hours. I then took temps again. The top came in at 110.7, so an increase of .3f. However, the bottom measured at 116.2, so an increase of 6.6f.
