Improvements after Publication
Further design improvements were made after the RA-L publication. The above instructions are still valid, taking into account the new parts. The changes are listed in detail below. The new files are also available.
Version 2
Summary: joint-friction reduction, less plastic deformation of the frames, thicker bellows for higher pressures, larger tube diameters for improved pressure dynamics
- Updated files (.stl, .stp)
- Upper frame
- Shaft diameter decreased to reduce friction
- Reinforced shaft holders to prevent deformation
- Lower frame
- Bearing diameter decreased to reduce friction
- Reinforced bearing holders to prevent deformation
- Reinforced mounting platform to prevent deformation
- Bellows
- Wall thickness increased to 3.5mm to increase maximum working pressure to 0.7bar (molding parts also updated for this)
- Tubes
- Tube diameter increased to 3mm to improve pressure dynamics (tube openings in upper/lower frame, tube connector and cable guide also updated for this)
