RB3 Tilted LCD Face Plates

thingiverse

This is a versatile LCD mounting system for RB1's and RB3's that can adapt to both Regular and Big versions of these printers. The system also allows the original RB1 LCD to be retrofitted with new buttons and cables, while enabling the transfer of all RB2 components into the RB3 frame. Additionally, the LCD case will fit seamlessly into the aluminum face plate version for both printer sizes. The part files included in this system cover a wide range of components such as the LCD case, the LCD mounting panel, the RB3 Logo panel, the center expansion panel specifically designed for the Big version, and bracket braces. These parts are precision-designed to be printed on an RB2 or RB1 10 x 10 bed. The bracket braces serve a dual purpose, providing support for both the printed front plates and the aluminum versions. A single brace is required for the Regular size, while two are needed for the Big version. They are attached to the bottom rail where the connection seams are located on the panels. A crucial step in assembling these parts is joining the panels using M3 (8mm long) bolts that are commonly found in printer kits. Pre-threading these bolts into small holes will significantly simplify the assembly process. Before mounting the LCD screen in the case, ensure that the panels are securely joined together. Additionally, place the buttons in their designated positions before attaching the LCD screen. All parts included in this system have been carefully scaled and oriented for printing using Cura. The LCD case tabs are designed to be printed at an angle, providing enhanced strength by avoiding flexing across layer joints. Given that these precision-fit parts require precise assembly, it is highly recommended to use calibrated filament found on the website http://www.thingiverse.com/thing:1037301. Print Settings: Printer: Rigidbot 2 Rafts: No Supports: No Resolution: 0.1 mm Infill: 22% Notes: I utilize Blue painters tape applied to an aluminum bed, washed with Windex, to achieve a strong bond and produce flat parts without warping or tape lifting. Initially set the bed temperature at 60C for PLA and reduce it to 45C once reaching a layer height of 0.5mm. This ensures that the upper layers do not warp the base. Run the first layer at approximately 15mm/sec to capture fine outline details in the logo letters, while maintaining a speed of 40 - 60mm/sec for the remainder of the print. Post-Printing: Removal from the printer bed: For part removal, allow the bed to cool completely (22C) and use a 3/4" chisel with the beveled side facing down to gently pry up at the edges. The parts will detach once you reach about halfway around the bed. I have successfully printed multiple sets without needing to replace the tape or re-level the bed.
