Quick-swap filament mount

Recommended Posts

Long story short, I ordered some filament from a local supplier, and it came on spools that wouldn't fit on the stock UM2 filament mount. Keeping in mind that I might encounter subsequent iterations of the same issue in the future, here's my solution to the problem:


The modified backplate design allows spindles of any diameter to be quickly attached/detached (provided one has been designed and printed in the desired diameter), and there are designs attached that will suit 31mm, 38mm, and 49mm spools.

That last diameter will work with the stock UM2 filament spools, albeit with a slightly loose fit. I've been printing for a few days using this setup, and have had no issues so far. Swapping between spools is very easy, even when incompatible dimensions are in play.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
