MKS Gen-L Case

thingiverse

Version 2.0 Update. After multiple prints of the design, I identified areas in need of improvement. Here's the list of changes: * The screen mounted in the cover has a 15-degree slant. Several interference points were found in the cover that made the fit challenging. The cover was re-designed to match the slanted case opening and eliminate all interference points. * All posts on the walls inside the case have been redesigned with a gradual build, eliminating the need for bridging by the printer. This should improve printing quality on less expensive printers prone to bridging issues. * STL files were regenerated to simplify geometry and decrease file size, resulting in faster slicer processing times without compromising precision. * A vanity change was made: the box's name (Sammy Box) is now only one layer deep (0.2), significantly improving print quality around the text. Version 1.3 Update: * General changes were made to reduce print time and filament usage, resulting in this version using half as much material as Version 1.0. * Increased hole tolerances to account for printer wobbling between layers. * Added missing cover mounting screw location, rectifying a mistake from Version 1.0 where the case was not fastened properly. * Lowered fan location to allow cooling under the MKS board and reduce box height. * Moved MOFSET mount closer to heating bed wires on the opposite wall. * Adjusted TL-Smoothers location for better alignment with X and Y axis plugs, moving extruder and Z-axis holes as well to enhance cable management. Version 1.0 of a case designed for FLSUN iPrusa printer but adaptable to any printer using 2020 rails (or 2040, 4040, etc). The case houses the following components: * MKS Gen-L controller board. * 1x 60x20mm fan. * 1x 60x10mm fan (optional). * 2x DC-DC adjustable PSU's (LM2596). * 1x Heated bed power module. * 2x TL-Smoothers modules. * 1x RepRap Discount LCD. When designing the case, I had several requirements: * The case should be mountable on a 2020 rail system. * All parts should be printable on a small 200x200 printer bed. * Components should be mounted with nuts instead of screwing into plastic. * The case should have no protrusions like bolt heads. * Larger fans running at lower speeds should maintain quiet operation while providing adequate cooling. * Air cooling direction change should be avoided to maintain effective cooling (no top fan with side exhausts). * The case should be able to hold all printer components. For this project, I chose a 60mm fan for two reasons: * A single 40mm fan does not move enough air to cool all equipment, especially when running stepper drivers like 2208 that generate a lot of heat. Running two 40mm fans at max speed makes things loud, but a 60mm fan moves three times the air of a 40mm fan and can be run at 60% its speed while still pushing as much air as two 40mm fans. * With all components mounted in the case, there was no way to maintain clearance without making the case deep. After all components fit into the case, I realized that there would be room for a 60mm fan. Here's the list of components bought to fit into the case: * MKS Gen L 1.0 controller: https://www.amazon.com/dp/B07BFSMTPS * DC-DC voltage regulators: https://www.amazon.com/dp/B01GJ0SC2C * Printer bed controller: https://www.amazon.com/dp/B01HEQVQAK * TL-Smoothers: https://www.amazon.com/dp/B071WG3SZQ * 60x20mm Fan: https://www.amazon.com/dp/B00ZS9P9IG Keep in mind, the fan listed is 24V since I'm using a 24V power supply. When ordering, you can use any voltage fan since you will have a DC-DC regulator next to the fan. Also, before printing, make sure to rotate the part so that the case opening faces up.
