• [x] Change cam follower from flat faced to roller
• [x] Design a way for the roller to attach (3D printed? bearing?)
• [x] Alter cam follower shaft to fit new parameters
• [x] Change mount from horizontal to vertical & merge pieced
• [x] Design top plate to be removable
• [x] Make plunger attach to super station
• [x] Create ~60mm tall housing for plunger module
• [x] Test print
• [x] Attach springs physically
• [x] Fine tune 3D printed attachments
• [x] Reprint

For 2/21 redesign:

• [x] switch from roller to flat faced follower (design + CAD)
• [x] adjust tolerances
• [x] redesign to be shorter
• [x] re-organize feature tree
• [x] Change mount holes to m4 tap
• [ ] change cam follower --> top plate attachment from press fit to a snap joint (if there's time)
• [x] move the main housing sketch plane closer to the cam
• [ ] Add thin housing to fully surround mechanism
• [ ] Attach full mechanism to the bottom of the science robot
• [ ] Double check tolerances & joints
• [ ] Print

Note: I'm worried that the spring will be compressed too far when the mechanism is fully extended, so keep an eye on that during assembly. If it is, lengthen the space between attachment extrusions & reprint housing + follower
