RAMPS 3030 Extrusion Mounted box

thingiverse

This is a nearly screwless Ramps+Atmega 2560 box with a 3030 extrusion mount base. I built it to make printing easy since my custom-built printer is quite new and not yet reliable for longer prints. The snap-in walls also make installation easier - just prepare the cables through the cable guards and walls, then install them onto the base, and snap everything together. So far I've printed all but the lid, and realized there's not enough room for cabling inside when using my TMC2130 harness. To fix this, I'll use a higher lid that adds another 2 cm of space - so customizing the depth parameter in whole_case.scad to make it 2 cm deeper would be helpful for people with more cables inside. The snap-in teeth do work, but the bottom one is loose. If you're trying to improve this, I'd suggest adding a similar spring-loaded part onto the bottom of the side panels - that would lock the panel in place and make the box more sturdy. When printing, remember to re-measure the distance of the arduino holes - mine were about 1.5 mm too close (the pillars were too close for the arduino), but I managed to screw it together anyway. TLDR: * works okay, not enough room for cables in my case (will be using the higher lid) * can be used without the walls as well, as a naked mount for 3030 extrusions * install cables through cable guards and walls first, then snap the box together * for those with a lot of cables, add 2cm to the depth parameter and regenerate the stls * the snap teeth hold the front part well, but the teeth near base are friction mounted only, which forced me to use hot-glue to make it more sturdy * atmega holes are not correctly positioned - re-measuring them and moving them a bit would be a good idea.
