Making A Filament Dryer from A Food Dehydrator

I’ve occasionally seen posts and videos about how to dry 3D printing filament using a food dehydrator, but never felt the need for one… until recently. I had a failed print that looked like wet filament was to blame, so I decided it was time to make my filament dryer. This post is about my experience – mostly good – with that dryer.

Printing replacement parts for your Prusa 3D printer

I recently bought and assembled a Prusa i3 MK3 kit, and decided to prepare for printing emergencies by printing a full set of replacement parts as soon as the printer was working well.

I’d found, in using my other printer, that even high-quality printed parts do eventually delaminate under stress: after two years, that printer’s X and Y idler supports developed fractures. Because I couldn’t print the replacement parts (and because doing the replacement seemed daunting at the time), I wound up sending that printer to the factory for repairs.

I’ve also seen notes and videos from people recommending a set of replacement parts as a backup, in case you break a part while adjusting or doing maintenance on your printer. Having replacement parts on hand is also a good preparation for helping a 3D printing friend when their printer breaks.

Estimating Remaining 3D Printer Filament

An idea’s been forming in the back of my head for a while: that it should be possible to estimate the amount of 3D filament left on a reel by simply weighing the reel with its filament, and subtracting the reel weight. Sounds simple, no?

Today I realized that it may be possible to modify a printer to give a live estimate of filament left on the currently-mounted reel, by “live weighing” the reel, and knowing the reel weight and filament density.
