U.F.O Mystery boxes generally ship out the 10th of every month. A timer will display on the website to display the last day to sign up to receive the current month box which will generally be 10 days before shipping.

Monthly UFO Box

Each Full U.F.O. Mystery Box will contain a minimum of 4 filaments at approximately 20 meters in length. Currently only 1.75 diameter filaments are available. At least 1 additional item will be included in each box as an accessory that is related to 3D Printing technology. Examples being: PFTE Tube Cutters, Build Surface Applicators, BuildTak Spatulas, Boron Nitride Paste etc. Electronics components will be provided for a project to go along with 3D printed parts that you will need to print yourself to build the final project.

Additional items may be included in each box depending on what we can acquire for any given month. Example items may include coupon codes for discounts on participating websites, gift cards, software license codes or free samples.

1 subscriber each month will receive a MOTHERSHIP UFO BOX! This box will include everything from the normal subscription box*, as well as 1 or multiple products provided by partners or sponsors. Examples of items: BuildTak Flexplates, BLTouch Bed Leveling Probes, Mosquito Hotends, Captubes Bowden Mega Pack etc. Subscriber will be picked at random by a computer by feeding it the names of each subscriber and seeing which subscriber name it spits out.

* Items may be substituted, for example if the UFO comes with a small item the Mothership may instead come with a large version of the same item.
