MKS Gen-L Case

thingiverse

Version 1.2 Update. After printing the case several times, I found a couple of areas that could use improvement. Here's the list of changes: * Case has a 15 degree slant for the screen mounted in the cover. Identified a number of interference points in the cover that made the fit a bit *tricky*. Re-designed cover to match the slanted case opening and remove all interference points. * Redesigned all posts located on the walls inside the case to have a gradual build. This removes all the need for *bridging* by the printer. This should make this case print better on the less expensive printers that tent to have trouble with bridging. * Regenerated STL files to simplify the geometry and decrease file size. As a result, slicers take less time to process the files without precision. * This is a bit of a vanity change. The name of the box(Sammy Box...) is now only one layer deep(0.2). This drastically improved the quality of the print around the text Version 1.1 Update. The following improvements have been made: * General changes have been made to lower print time and amount of filament used. This version uses half as much material as version 1.0 * Increased hole tolerances in case printer wobbles between layers. * Added missing cover mounting screw location. Yep, version 1.0 was not fastened to the case. My bad. * Lowered fan location to allow some cooling under the MKS board and to shrink the height of the box. * Moved MOFSET mount on the opposite wall so it's now closer to heating bed wires. * Moved location of TL-Smoothers to be more aligned with X and Y axis plugs. Other exis holes(extruder and z axis) have been moved as well to improve cable management. Version 1.0 of a case designed for FLSUN iPrusa printer but will work with any printer that uses 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-Smoother modules * 1x RepRap Discount LCD When designing the case, I had a few design requirements: * case should be mountable on a 2020 rails * all parts should be printable on a small, 200x200 printer bed * components should be mounted with nuts instead of screwing into plastic. * case should have no protrusions like bolt heads * use larger fans running at lower speeds to keep things quiet while maintain adequate cooling * avoid air cooling direction change(no top fan with side exhausts) to maintain effective cooling * case should be able to hold all printer components For this project I chose to use 60mm fan. This was 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. They only way to address this is to run two 40mm fans at max speed which makes things rather loud. 60mm moves 3x amount of air of a 40mm fan which means I can run it at 60% its speed and still push as much air as a 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. Bonus! 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 such that case openning is facing up.
