I knew I wanted to get rid of the wall clock which we had…. Simply because it’s plastic and not 3d printed.
When I took it down to change the battery and discovered the paper decoration has been peeling off obstructing the movements of the hour & min arms…. The clock never went back up on the wall.
I fired up Sketch-up… and wore my thinking cap, hours later I had the design completed.
To make one I used
• A clock engine with arms,
• Hot glue
• Pack of 12 pencils. In the Netherlands the pencil comes in pack of 18
• Print filaments
• And of course a well calibrated 3D printer " TeeBotMax" (https://www.thingiverse.com/thing:248654)
Material Cost :
Hot glue gun + stick : 3 Euro
Pencils: 1 Euro
Filament: I had two colors from previous project (Purple & Pink). (Yup... got kids..)
Print Time: Round Base & 0.4mm layer height (1 hour), the hours (1- 12): 0.4mm layer height (4 hours)
Clock engine: Free from an old clock. The design fits clock engine of 56mm x 56mm x 16mm. (2-3/16" x 2-3/16" x 5/8").
The STL files
The files are in two parts
• The Round base that holds the insert
• The hours (1-12)
Printing in two colors.
Printing the hour arms plastic in two colors makes it easy to see the numbers from far. Three ways I can think of to do this, if any one has any other option please share in the comment section
- Use your multicolored 3Dprinter
- Use a single color 3dprinter and change filament when it is about to start printing the number….(around 11mm).
- Print in one color and use a permanent marker to paint the number top.
Starting to think lots of cool 3D printed projects can be done using these Pencils…..Wall decorations.. Name tag… if you have more please share. Feel free to suggest modifications, as I will be printing a lot of these as gift in the future!!
