Executive Desk Toy

A simple executive desk toy designed to get attention.

As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 14.12.1, and 3D printed in PLA on Ultimaker S5s.

I acquired the following parts:

1. One bell: https://www.amazon.com/Service-Dinner-Counter-Trivia-Training/dp/B0DYDWRYZT

I 3D printed the following parts at .15mm layer height, 20% infill:

1. One "Axle, Lever.stl" (attaches the lever to the base, do not overtighen).
2. One "Base.stl".
3. One "Bell Mount Bolt.stl" (attaches the bell to the bell mount).
4. One "Bell Mount.stl".
5. Four "Bolt (M8 by 1.25 by 4).stl" (used as the four feet for the base).
6. One "Bolt (M8 by 1.25 by 8).stl" (attaches the bell mount to the base).
7. One "Bolt (M8 by 1.25 by 14).stl" (fixes the guide in the bell mount).
8. One "Guide.stl".
9. One "Lever.stl".
10. One "Shuttle.stl".

This mechanism is a medium precision print and assembly using at times very small precision 3D printed parts in confined spaces with highly precise alignment. Prior to assembly, I test fitted and trimmed, filed, drilled, sanded, etc. all parts as necessary for smooth movement of moving surfaces, and tight fit for non moving surfaces. Depending on your slicer, printer, printer settings and the colors you chose, more or less trimming, filing, drilling and/or sanding may be required to successfully recreate this model. I carefully filed all edges that contacted the build plate to make absolutely certain that all build plate "ooze" is removed and that all edges are smooth using small jewelers files and plenty of patience.

This mechanism also uses threaded assembly, so I used a tap and die set (M8 by 1.25) as required for thread cleaning.

I hope you enjoyed it!
