Printrbot Z-Spool+Stabilizer+Wobble

thingiverse

First-time SketchUp user here, creating a design for my custom Tall-Z Printrbot+. Seeking feedback on printability, particularly the wider top part that will be printed vertically. The second model features rounded edges. Input welcome! In theory, this is how it works: 1. Print 1 left and 1 right component (not yet uploaded). 2. Insert into 12mm smooth rods. 3. Also fit into 5mm threaded rod. 4. Attach a 5/16 threaded rod at the back, connecting the two smooth rods, and secure with nuts. 5. Add another 5/16 threaded rod at the top for spool holder, securing with nuts.
