I have spent a lot of money and time building the scrap waste extruder from Extrudex on Kickstarter. I have yet to product any new filament, but I blew out the power supply and had to wait to get a new one, totally my fault. Anyways, I made these to help sift the scrap plastic after I ground it in a blender.

This came about when my mother-in-law needed new clips for her wall lamps to hold the cord covers in place. Turns out that the extra ones I made were perfect for holding my needle-nose pliers

I have put together a DIY dehumidification cabinet for my filament. I have a small dehumidifier with a drainage tube going to my sump and I used rubber grommets from Amazon to run the plugs through out to the humidification controller, also purchased on Amazon. So far, I'm able to get it down to about 40%RH, but I'm experimenting with removing the lid from my filament dryer to help warm the air inside and help the dehumidifier pull out more moisture.
