Fan powered bottle dryer that uses a single 5015 fan to speed drying times. Sized for a minimum ID of 16mm for the bottle mouth.
We reuse bottles from a particular Italian soda and that means washing them out. They have a small mouth, only a little over 16mm ID - so I found alexthurlow's powered bottle dryer and was all set to print it until I realized the OD of the nozzle was 25mm - too large to fit inside the bottle. I enjoy designing parts in Fusion 360, so I used his design as an inspiration for my from-scratch design. I noticed that with the smooth outside of the nozzle, if it matched the ID of the bottle, the air wouldn't have a route to escape, so I changed my design to have a path for air to leave. I also realized that having the fan farther out resulted in a longer area that would require either bridging or support material, so redesigned it with the fan tucked in closer to minimize this area. I also made the transition from the blower exit to the round nozzle as a loft to hopefully decrease flow losses. As it is, with an 8.5V power supply on the fan (thought I had grabbed a 12V) the air jet is surprisingly strong. In a test with a larger mouth bottle (around 40mm ID) the bottle was nice and dry in maybe 15-20 minutes.
The bottles we use with a 16mm ID are quite tall, nearly 300mm (12") tall - standing them up on the mouth isn't exactly the most stable setup. In my testing they don't tend to fall over, but it would be good to make sure the bottle and blower are on a flat, stable surface before letting it sit to try.
With a larger diameter bottle, it's possible to put the bottle off-center so it isn't partially covering the fan inlet. I could make the support fin opposite the fan longer so a larger bottle could be handled off-center. I'm also curious if blowing in air from the side might help circulation which would result in even faster drying times. The current design works for most of our applications which range up to standard bicycle water bottles.
Note: I wanted to try Cults3D as a possible alternative to Thingiverse, but after giving it a bit of a look, I'm not super impressed. Feel free to visit my Thingiverse page if they can manage to keep that site running:
I went to school as a mechanical engineer, and got interested in 3D modeling, specifically the SDRC I-DEAS CAD/CAM software system. This interest got me my first job working for a CAD/CAM reseller doing pre and post-sales support. I was lucky to be involved in 3D printing in the early 90s - for a demo of rapid prototyping, I modeled the mouse from my HP-UX CAD workstation and it was rendered via stereolithography. I still have that model, but across the years I stopped using CAD and moved to systems administration. Now that 3D printing is affordable and mostly reliable, I've gotten into it and am having a blast. I printed all the usual cute little trinkets and tchotchkes, but quickly got bored of that. What I find most interesting is needing something, then spending a little bit of time in a CAD program and soon after that having a real, functional version of the part in my hand.
I'm a cyclist and bike mechanic as a hobby and a side job, and have found endless applications of 3D printing to both bikes and bike maintenance. Coworkers have also come to me with many varied requests, each of which has been an interesting challenge and an opportunity to learn.
I am constantly learning, constantly trying to challenge myself to learn new things and technologies, so hopefully as I progress my designs will continue to improve.
