Kossel electronic Housing & display case

thingiverse

Human: A simple setup for RAMPS and Arduino, plus the Reprap discount smart controller display. Also added two straightforward holding brackets for an ATX power supply, so you can mount it out of the way under a table. I thought it would be a great project to design some parts to keep my 3D printer organized! Designed in FreeCAD, I'm happy to share the FCStd files if you want them, just send me a message. Both cases clip onto the base of the printer using the 'Chassis_clip' part. You'll need some M3 machine screws to attach them to the cases, and some M3 screws and plastic washers to attach the Reprap controller to the case. There's space for an on/off switch at the side of the display case, I use this to disable my ATX power supply so I can cut the power if something is going wrong! It normally stays on all the time and I turn the printer on/off with software. The display case works best printed with the 'top' face down on the print surface (I think). You'll need to print supports for the SD card slot and switch space. I used the default coarse support in KISSlicer and it worked well. The electronics case has space for two 40mm fans. I connected these to a fan extender and run them only when the motors are on, but you could run them all the time if you don't want to bother with a fan extender. I printed this with supports for the fan holes, again the default coarse supports on KISSlicer worked well. The ATX power supply brackets were designed for my CX430 power supply (pictured) but should work with others too. You'll need some tapered head screws to fasten the brackets to the underside of your table/bench. Before you print this, please keep in mind that there are a lot of slightly different versions of RAMPS and Reprap Discount Smart Controllers out there - I strongly recommend checking the STLs will fit the parts you have before printing, as some of the parts take a while to print! I hope someone else finds this useful - thanks for taking a look at my design! Print Settings Printer: Openbeam Kossel XL Rafts: No Supports: Yes Resolution: 0.2 (important for the electronics case lid) Infill: Not important - I used 25% Notes: The electronics case lid slides into place and is held in place by slotted rails. The rails need to be printed with a relatively fine resolution (I used 0.2mm, 0.3mm would probably be fine too). You may need to tidy these up a bit with a craft knife after printing to make the lid slide on.
