DJ Control Mix Adjustable Stand with Foldable Handle

Description

My goal here was to create a useful stand with a minimal form factor. This stand features adjustable angled legs and a foldable handle, all of which can be tucked within the 10mm form factor of the stand and secured with simple wheels to prevent them from flailing. The top grip easily removable, allowing for a secure fit without compromising ease of inserting and removing the DJ Control Mix from the stand.

Print Instructions

I went through several iterations to make it print as smoothy as possible while retaining function, but it can still be a somewhat tricky print. You will need good bridging for the wheel stopper. I provided test files to make sure the wheels and joints print correctly and fit together as those are the most difficult parts. After tweaking the tolerances, I got them to be consistent on my machine, but they are giving you trouble, I also provided files with the tolerances for those parts increased by 50%. If you want to do some fine-tuning, STEP and Fusion files are provided. If you use Fusion, all tolerances were set as model parameters so it will be easy to change.

I printed everything in PLA with 0.2mm layer height, but it should work with other hard materials and lower layer heights.

Additional needed materials:

Super glue or similar to secure side and middle components.

Test File:

Print the main section lying flat with the wheel touching the bed. Use manual supports on the joint. Print the side section laying on the same orientation, with manual support on the joint. Make sure the wheel can easily rotate and the joints fit somewhat smoothly. The joint tolerance is applied to the main section, so you don't need to reprint the side section if you end up changing it.

Side Sections:

Print them lying flat with the wheel touching the bed. You will need to enable manual supports and pain the underside of the joint that connects to the middle sections, as well as a small portion of the legs with the wheel cutout. Notably, one of the legs will feature a floating cantilever due to the wheel cutout, so make sure to support that.

Middle Section:

Similarly, print laying flat on its back, with the wheel touching the bed. You will need support for the joints that connect with the side sections, as well as the upper portion of the grip. I found that tree supports work really well here, as they can come from the sides and the small gaps between the handle and the main body, minimizing support material anchored to the part.

Top section:

Print lying flat on its top, no supports needed

Nuts:

Print lying flat, no supports needed.

Assembly

Make sure the joints between the middle and side sections are working smoothly, take them apart again, and apply a fair amount of super glue before putting it back together.

For the top sections, simply put it after the controller and secure it with the nuts.

Troubleshooting/Post-processing

Before I dialed in all the tolerances, sometimes the wheels would get stuck to the part and not move. I managed to salvage some of those by prying them from the part with a butter knife. I've since thickened the middle section of the wheel, but do still be careful not to break it off.

Depending on how well the supports come off, you may have difficulty connecting the middle and side sections, as well as screwing the threads. These should be easy to fix by filing down those parts

On the angled legs, there is still a small amount of give on the wheel. If a more snug fit is desired, what I did was soften the wheel with a hair dryer and bend it slightly downward, making it concave. This led to very snug fit with the legs sitting perfectly within the profile of the stand. Alternatively, you can decrease the tolerance for the top surface of the wheel from the current 0.6mm if you trust your bridging (around 30mm at the longest section).

The one thing I wasn't able to test was the fit to the DJ Control Mix as I don't own one, so I went with pretty tight tolerances to be sure it wouldn't be too loose, at the risk of it being too tight, as you can always file it down for a perfect fit.
