Yet another Ramps+Arduino Mega 2560+LCD 12864 + tinyfan enclosure

thingiverse

This kit has been designed to be printed in several parts then glued together. In view of commissioning the second extruder I needed a fan extender. This small device hangs out from the Ramps board, and I had to design a larger enclosure. In the prototype, I designed the slots for two fans, but after printing I found out that one is noisy enough and in any case I don't have enough space for both of them. I originally designed all the slots using several 3D models of Ramps+Arduino and LCD12864 found on the Internet. Then, I realized that my hardware didn't match 100% with 3D models. It was slightly different, especially in connector size and position. For the same reason I preferred to design the front board separately from the rest of the LCD shell. I left some clearance around the slots, so I don't expect that you will have too much trouble. If you really need some adjustments ask me and I'll make a dedicated STL file for you. I also put my name on the top lid and on the LCD shell. If you want your own, ask me and I'll prepare a dedicated STL file for you. Edit 25/05/2019: I added a front file with two holes for fans. The file name is ramps_encl - front_side-2fans.stl. Print Settings: Printer: D-bot Core-XY Rafts: No Supports: No Resolution: 0.1 mm but 0.15 should also be okay Infill: 50% Notes: Supports needed only for LCD enclosure supports Post-Printing: Hardware Needed: Some drops of CA glue Some M3 screws Some M3 nuts One fan 40x40x10 mm Instructions for Ramps Enclosure: Put the M3 nuts inside their pockets. Glue the right rail and the front rail (green) on the bottom baseplate (black). Glue the right side (red), the front side (green) and the rear side (orange) on the baseplate. Slide the board inside. Connect the left side (blue) with the previous assembly using two screws. Connect the top lid (yellow) using four screws. Instructions for LCD 12864 Enclosure: Put the M3 nuts inside their pockets. Glue the button rail (red) to the front board (white). Glue this assembly to the LCD shell (dark grey). Turn the assembly upside down. Slide the reset button (bronze) into the button rail. Put the LCD 12864 into the shell. Connect the bottom lid (orange) using four screws. Glue or simply connect by pressure the two blue supports using the four slots into the bottom lid. Finally, you can attach the LCD to the board enclosure by sliding the blue supports in the rails on the yellow top lid.
