Pencil Holder Jig

thingiverse

My daughter received an impressive set of 70 vibrant colored pencils on her birthday, which looked pretty cool in their clear plastic storage case. However, it was too flimsy to keep around, so I thought about creating a sturdy wooden pencil holder instead. Unfortunately, I knew that hand-drilling the holes would result in noticeable variations in placement, so I came up with this hole guide as a solution. The holes are 8mm in diameter and spaced 13mm apart, and I used a 19/64" index drill to create them. Print Settings Printer: Flash Forge Creator Pro Rafts: Yes Supports: No Resolution: .3 Infill: 20% Notes: Included solid diaphragm every 20 layers (so ~ 3 solid layers) to provide additional rigidity. Post-Printing Mount the piece to a wood block and drill it. I did two small pilot holes in two random holes, then screwed the plastic piece down to the wood. Next, I set the drill depth stop on the drill press. Then came the tedious task of drilling hole after hole, carefully centering each one by leaving the drill spinning, letting it self-center on the beveled holes, and finally clamping the piece before drilling. If you have a "little helper" on hand, they can be incredibly helpful in holding a vacuum up to the piece to remove any excess wood. Once all but two holes are drilled, insert a dowel into two of them, remove the screws, and drill the remaining two holes. How I Designed This I designed the block using Free Cad, employing the part designer tool and sketcher tool rectangular array to create all the holes precisely.
