I could not find a print bed drip support bracket for the Creality Halot One Pro, so I tried to make one. This is my attempt. The pictures show Ver 1 holding the Print bed that freshly printed Ver 2 is attached to. If you use the:
Creality_Drip_Support_V3.cxdlp just print it direct to your Halot One Pro.
Creality_Drip_Support_V3.fw3d file you will the the Formware Slicer.
Halot_One_Pro_Drip_Support_V2.FCStd you will need FreeCAD to edit and view it.
Halot_One_Pro_Drip Support_V2.stl you will need to tilt, hollow and support it. Use a wall thickness of 2mm, Internal supports and plenty drainage and a raft with 2mm supports. The resin is tough but also quite pliable so good solid supports are necessary

built in

Sunlu Toughness Resin (White)
4 Bottom Layers at 20 Sec/Layer, Rest time 1 Sec, Lift 6mm at 2mm/Sec
Normal layers at 1.5 Sec/Layer, same rest, lift dist and speed
The Halot printable file has all internal supports and drainage holes already built in. Just print.
If you fiddle with the .Stl, you should add internal support and Drainage

After printing I drained the part, and washed in Creality Wash and Cure station (UW-01) in Isopropyl

I used Freecad Ver 018 to design it, printed the first version and then updated it and fixed some issues. It does worry me that the build plate does stick out a bit in front of the Printer but moving it closer in also moved it lower and closer to the Vat, limiting the size of printable things. Im also not sure if it will be universally applicable to ALL printable items, depending on how they might have parts sticking out that may drip outside of the Vat. I keep a paper towel over the front of the printer for such cases. My sense its not perfect but suites some of my needs.
