Shortly after creating my first filament dehydrator https://www.thingiverse.com/thing:2520281, I found CreativeTools' Filament Spool Holder. My first version worked fine, but I found some shavings on the spool holder when changing filaments, caused by the friction between the holder and the spool. Also, my original holder was only sized for certain spools, not as universal as I had expected. Not a big deal, but I'm a big fan of maximum efficiency...so here you go, a slightly better version than the first.
Here are the links I had in my first version: Dehydrator: https://www.amazon.com/Flexzion-Dehydrator-Food-Fruit-Dehydration/dp/B01J51JLCC/ref=sr_1_23?s=kitchen&ie=UTF8&qid=1499306986&sr=1-23&keywords=dehydrator+machine
and Wilton's cake caddy, which I got from Joann http://www.joann.com/cake-caddy/5717806.html#q=cake%2Bcaddy&start=1, for about $10 (don't forget to use your coupons!)
- Sometimes Amazon is out of stock, they do seem to have it in at this time. I know for sure that the nutrichef PKFD14 (and 14BK) are not the right size for the caddy, but perhaps it will work with Westinghouse http://amzn.to/2Bsxth4 or Rosewill http://amzn.to/2HdMbJj.
- You could use Dr. Boo's Filament Dryer Spacers https://www.thingiverse.com/thing:2797196 with a 5-star Chef Food Dehydrator, but since the walls are not clear, you won't be able to see how much filament you have left.
- I also found out Taulman has a dehydrator design similar to this, you might want to check it out if you don't want to go through the trouble of DIY.
The only other thing you need is 2 #4 x 5/8" pan head screws, maybe spare thermal fuses and 1/2" rubber stoppers (see below in Tips). If you want suggestions for other dehydrators and tops, look on Tinkerman's original dehydrator page: https://www.thingiverse.com/thing:1618037
I didn't mess with CreativeTools' duster, the filament is in an enclosed space, not likely to gather dust. My snoot is intended for a PC4-M6 Male Straight Pneumatic Connector. The PTFE tube keeps the air from reaching the filament before it reaches the printer and keeps the filament from crimping.
Special thanks goes to CreativeTools and Tinkerman for sharing their original ideas!
*See my extra tips below!
.25 for large objects, .1 for small
Printed the snoot .1, only with base supports. The threads printed a little warped without full supports, but it still worked for me.
The base and spool will need to fit into each other, I recommend testing your printer with https://www.thingiverse.com/thing:2648645 to make sure your calibration is good.
Tips and Tricks!
I threw some dessicant in the dehydrator under the spool, it helps to keep the humidity down when it's off.
I also got a timer to turn on the dehydrator 2 or 3 times a day, 2 hours each, to keep any moisture from coming in. I recommend an electrical, the mechanical ones can be pretty noisy.
*Tip: Be sure to have the dehydrator sitting on a flat surface with no holes. If there's too much air flow from underneath, it won't get hot and can eventually burn out the heating unit (a resistor I think?).
**Note 6/3/18: After using this for half a year, I figured out some things that might help you:
If you're running your dehydrator as much as I am, then the thermal fuse inside will eventually break down. Instead of buying a whole new one, buy some extra fuses 142deg C (https://www.amazon.com/Microtemp-Thermal-Fuse-Cutoff-SF139E/dp/B0127L0PKO), and replace them, very easy if you use crimp connectors. I have blue dessicant indicators sitting inside to signal when the dehydrator is no longer dry, hence the dehydrator is not getting hot and the fuse is blown.
One of my dehydrators would rattle when starting up. At first I thought it was the dessicant beads falling in, but I figured out it was the pressure building up inside the container, messing with the fan. I drilled 3 holes 13/32" dia on the top (2 top-front, 1 back) and got (3) 1/2"-top rubber stoppers. I remove the stoppers when I run the dehydrator, and replace them when it's off. Haven't figured out how to make it work in conjunction with my timer yet, maybe just make sure to be around to remove/replace the stoppers.
