Dehydrator Spool Holder Bottom Remix
Description
USE AT YOUR OWN RISK ===================== This started as a remix of 3dMakernoob's bottom piece of his [Dehydrator Dual Spool Holder](https://www.thingiverse.com/thing:3293081) to not require bridging (FilaGuideBot.stl). After printing, I found that it sat fairly loose in [my Dehydrator](https://smile.amazon.com/gp/product/B018UR4XJI), so I redesigned it to screw directly onto the dehydrator itself in place of the original white plastic cover over the fan and heating element (see pictures). I left the metal cover in place, so I **think** this is safe, but this is an electric heating device and I am no expert, so use at your own risk. UPDATE (22 MAR 2020) === I had trouble drilling the passthrough hole for the tube fitting in the wall of trays the without breaking it, so I decided to simply print my own walls in 6 pieces. They press fit onto the dehydrator base and then I secured them to each other with cable ties. After that it *still* wasn't working. I noticed that the filament was always taut and that the spool made a loud screeching sound, so I redesigned using 6 [bearings](https://smile.amazon.com/gp/product/B07211VH78/) and now it's smooth sailing. UPDATE (29 JAN 2021) =================== Snapped the central column off my **SpoolHolderB2** so I printed a new one with 100% infill. Bearing wouldn't fit, so I made the central column a little bit thinner. While I was at it, I changed from a 3-leg design to a 5-leg design. UPDATE (21 OCT 2021) =================== * I've been having some problems with the filament occasionally falling under the spool and under the holder and getting wrapped around the column. To remedy this, I made the hole in the wall smaller so that the filament always has to travel up a little before exiting. * I didn't like that hot air was blowing out of the wall holes not used to pass filament, so I taped them over (as seen in the picture for my [Minimal Master Spool](https://www.thingiverse.com/thing:4513479)). It's not worth re-printing the walls for that, but I've added a wall section with no hole to solve this more elegantly for those making new walls. #Tip Running the dryer all the time makes my makerspace the warmest room in the house. The dryer actually uses twice as much power as my [Prusa Mini](https://shop.prusa3d.com/en/3d-printers/994-original-prusa-mini.html). So my primary electricity cost has been running my central A/C to make the rest of my house freezing-cold so that room will be livable. I recently picked up a [small appliance timer](https://smile.amazon.com/gp/product/B00P76URH8/) and use it to run my dehydrator on a 50% duty cycle, which has greatly mitigated the situation.
