Alien3D UFO Sample Spool

Designed with the samples from the Alien3D UFO Boxes in mind. Outer core dimension is 102mm to match a masterspool outer core. Inner core is 50mm and the sides are 150mm. Only 1 file needed and printed twice as it is meant to be identical parts that snap together.

**Spool**
v1.22 - Snaps together, little bit hard to get back apart due to layer line grippage
v2.1 (WIP) - Has a slotted connector to twist in to, test prints in progress. 9/20/2018
v3 - Uses same friction connector as v2 but redesigned for faster printing/less material

**Clip**
v1 - Clip for clipping onto the side to hold loose filament end.
