SmartRap modified Base Plate variations

thingiverse

This user faced difficulties while printing the 0.5 version of the base plate and encountered issues related to wall thickness at the bearing pole and the filament feed blocks. They attempted a fix by adjusting the holes for the filament and bearing pole, but these required manual drilling as they were unsure about screw sizes. The user also removed the top T-Slot of the larger filament guide block, wondering about its functionality. They suggest an improvement with a movable and spring-loaded bearing to adjust compression on passing filament. The design is compatible with 3mm filament when required in the future. The user encourages input and mentions that it printed without issues on their Solidoodle with .3mm resolution. The user has updated the design, adding a version with embedded bearing supports and reducing parts count to 11. They have also reintroduced T-Slot as per Serge's design while keeping other versions for users' customization preferences. In another update, they fixed the bearing mount issue by making it a separate part, suggesting inserting a small spring between the new bearing mount and LM8UU bearing mount, secured with an M2.5 or M3 screw. Users can also consider putting springs on both sides of the bearing mount for better support. Printing note includes corrections for two missing holes in some versions and adjustment to the protrusion for the filament with T-slot. To ensure tensile forces are withstood, users can apply liquid superglue as a tough shell over the surface. The user shares a photo of assembled base and base plate along with Y plate. Lastly, they have readded two missing holes in response to a request, drilling them out if necessary. They suggest using 4mm holes for wider spaces that can be manually widened with a drill.
