Missile Turret Pen Holder (UPDATED) - Gridfinity Compatible

I wanted a compact Missile Turret style pencil holder that fit in a 2x2 Gridfinity space. I ended up creating this model in 3 pieces. Holds 12 pens/pencils. **Due to the advancements in accuracy of 3d printers I have found that the existing slides are too small. I am leaving them up for the older printers. I have added two new slides. 5.25 and 5.5. The 5.5 fits nice and tight printed at 0.2mm layer height from my Kobra 3.** *I have added a couple options for larger slides. The 4.25 option is the original. The 4.66 option has a lot less play. The 5 option should have little to no play, but on some printers may not fit at all. Please print out the Test_Slides first to determine which works best for you before printing the full models.* Base: 78.71mm long, 78.71mm wide, 61.5mm tall Turrets: 54.55mm long, 32mm wide, 61.67mm tall Overall Assembled: 78.71mm long, 78.71mm wide, 95.96mm tall Pen holes: 12mm wide (holds standard Sharpies)
