Box for MKS 1.4 Ramps Upgrade ANET A8 w/ Pi 3

thingiverse

I am actively working on a significant project to fully upgrade my Anet A8 with the MKS RAMPS 1.4 Board and all other features that can be incorporated into it. This box has not been printed yet, so I am unsure about everything being perfect; there are a few things like clips, hinges, and light bars that seem to work on paper but may not function in real life. Features: - Mounting position for the MKS RAMPS 1.4 main board - Various access holes for related wires - Plenty of room for stepper drivers, including smoother boards when used between the stepper driver and the main board - Removable cable management clips along the back to help keep things tidy; there are nine positions available, with four overlapping the buck-boost and cannot be used together - Three 40mm fans located directly over the stepper drivers - Two positions for hotbed/hotend mosfets - One position for a DC-DC buck converter (Yeeco XY-014: http://a.co/3vdBNvL) (I will probably use this for illumination things) **PS. Do not use this buck for 24 to 12vdc and USB power for the Pi 3 at the same time; smoke will happen** - One mounting position for a Raspberry Pi 3 - One ribbon cable pass-through for Pi 3 Camera - Side panel is hinged to allow easy access to all inside boards without disconnecting the Pi or mosfets; this will use a 3mm peg - Case edge ridges to help with cover alignments and add rigidity when closed - One light bar at cable management; I am not sure if I will use this or not, but I wanted to make the mounting position and parts into the box in case I decide to use it --My hopes were that this would support some LED strip tape as well as support some of the 'mid board' cables like thermometers and end stop switch wires - All screw/mounting holes are made small so that they can be pre-drilled to size; this should make it easy to use different hardware and maintain "thread-bite" 04-27-18 Update: I started printing on this. Made some tweaks that have not been posted yet, including some clearance in the hinge (fillet) and adding supports for 125mm and 135mm board lengths. Not sure if 125 will be useful for some, but left it there; these can be cut off for those who need 135. 04-30-18 Update: Successfully printed the main box and side cover; holes lined up for the main cover properly. I will likely remove the 125mm holes as I do not think there is a 125mm MKS GEN version. The side cover is a bit tricky to print as there are hinges; I chose to print the hinges down and use a raft. Currently printing the top and clips. 05-09-18 Update: Major update. Printed out the first version and learned a lot of things; top cover didn't quite fit due to shrinking plastic. --Removed the parts that catch so this shouldn't matter. There are still some warp issues that are unavoidable, which should be handled by the screw points that hold the cover shells together. --Added lots more cable management. --Added a side cover to support two buck converters with easy access to displays and buttons; my thought here is that one could provide a step down from 24v to 5v for the pi, while the other could provide a step down from 24v to 12v for lights and cooling fans. -------Added a standoff file if these buck converters are used. -------If they are not used, the holes are there for future upgrades but will be smooth with no standoffs hanging off the side. -------Added wire pass-through for this area into the case. -------Left the inside posts in case this is desired by someone. --Removed the 125mm holes as I figure these are mistakes and will not be a real thing. --Reinforced the hinges on both parts; I did not intend these to be heavy-duty hinges, so they may break off after 15-20 openings if you are not careful. --Combined the top cover and door into one part which made everything much simpler. --Opened up the fan holes by 3mm due to a bad measurement. --Added two clip versions: v1 is oversized (0.5mm) long-wise to give extra clip force, while v2 is right-sized. 05-31-18 Update: Added Pictures
