Pull Handle

This pull handle has been designed to be printed as a single piece/component without supports. The original intent of the component is to mount to either a Creality Halot Lite resin printer, or a Creality UW 02 Cure and Wash station; Take note of the overall handle width when considering use cases other than the machines listed.  The pull handle mounts to the top of the UV/dust cover to provide a convenient way to remove the cover without the risk of transferring resin to the cover.

Several features of this handle include:

• Fasteners - The handle accepts ¼ inch diameter by 1 inch long shoulder bolts or button head screws; M6 x 25/26 mm long fasteners may also work. 
• Overhang - When printed upside-down, the greatest overhang will be 32 DEG to the build plate
• Bridging surfaces - The counterbore has been modified to support 3D printing, and incorporates 2x orthogonal surfaces that are .15 mm thick.  Feature thickness is intended to support a .15mm layer thickness, with linear travel when extruding the bridge.
• Ergonomics - With a gap width of 5.1 in (12.95 cm) and height of 1.5 in (3.81 cm), the handle is quite large.  The intent behind being so large is that the handle may be easier to grab with gloved hands, or when juggling multiple post UV printing tasks.

Suggested printing parameters, assuming PETg filament:

• Base filament settings - Prusament PETg profile
• Nozzle - 0.4 mm
• Layer height - 0.15 mm (note that this supports the 2x overhangs within the counterbore features)
• Supports - Off
• Perimeters - 3 (if modifying extrusion width, otherwise 2 is suggested)
• Extrusion width, Perimeters - 0.6
• Extrusion width, Infill - 0.6
• Extrusion width, Solid Infill - 0.6
• Cooling, Bridges fan speed - 100%
• Cooling, Disable fan for the first - 5 layers

Total print time for the modified Prusament PETg profile settings is 7.25 hours for a single handle.
