DNA Helix Pencil Holder

thingiverse

This is a "two parts in one print" design that eliminates the need for rafts or supports.Print the "DNA_Helix_Pencil_Holder_Full_06.stl" STL fileAfter printing, remove two distinct parts from the print bed.a. The outer print serves as the bottom of the helix.b. The inner print is the top of the helix.(Optional) Use "DNA_Helix_Pencil_Holder_Optional_U_Snaps.stl" x 2 on the outside of the helix to secure the top and bottom parts together. These are pressure-fit snaps that fit snugly on the outside of the Helix, requiring a screwdriver to gently lever out if removal is needed.Assemble with adhesive or your preferred bonding method to make the connection permanent. (Super glue was used.) With the snaps in place, gluing may become optional.Insert pencils and display the finished product.Take a picture and share it on Thingiverse :).I also have a Sharpie version available: http://www.thingiverse.com/thing:1924310,I've received requests for a smoother version: https://www.thingiverse.com/thing:2789838,Printer SettingsPrinter: Maker Select i3Rafts: NoSupports: NoResolution: 0.15Infill: 20%Notes:Update Notes:10/27 Added tongue and groove design Added U-snaps and holes for an optional "Glueless" fit Added separate files for dual printers and customizations:a.

Supports may be needed for the top design. If a successful print is achieved with the tall STL file, please share settings used so they can be posted here.For users with standard-sized printers, use the "DNA_Helix_Pencil_Holder_Full_06.stl" file and follow the provided instructions.Post-PrintingSecure the bottom of the helix to the top of the helix using snaps or super glue.
