3D Mechanical Engineer to design a Precision Device

The Device is designated to get the powder out of a standard gelatin hard capsule.

I need an experienced 3D mechanical engineer to design a precision mechanical assembly for me. This assembly must be able to clamp a powder containing standard size (#000, #00, #0, #1, #2, #3, #4 & #5) gelatin capsule and break it into two halves by applying a controlled force.

Key Requirements:
- The device must be small, less than 10 cm in size.
- The primary material for 3D printing will be PLA (Polylactic Acid) (or any other filment).
- The level of precision required for the capsule clamping mechanism is low, greater than 0.5 mm.
- Device should be simple, not more than 15 parts (the less the better)

Ideal Skills and Experience:
- Proven experience in 3D mechanical engineering, particularly in designing precision devices.
- Strong knowledge of 3D , abilety to produce set of STL files for printing.
- Familiarity with designing assemblies that involve applying controlled forces.

Please provide previous work samples and references when applying. Your ability to meet the specifications, and deliver on time and within budget, is crucial.

Payment will be done in milestones
a - agreed on design concept and simple draw - 20%
b - STL files for the agreed design - 60%
c - Physical QA (we will print the STL and see if device works) - 20%

Please Bid ONLY if you have expirience in Design devices and make STL for it
Please send me a sample of STL you made for mechanical devices.
