Round face project box

thingiverse

It's a custom project box, a tub with a lid and specific mounting holes and bosses designed to hold parts securely in place. This box fits snugly on the build-plate, barely, requiring about 24 hours for the box itself and around 8 hours for the lid. OpenSCAD designers should be able to modify parts from this design for their own projects. I think the honeycomb texture is helping with shrinkage issues and making removal of the big flat plates easier at the end of the build, though it was still pretty hard for me to remove the box from the plate. Compared to a 4"x4" flat bottomed build I just did, this hex pattern is indeed easier to get off the plate, but I discovered a new technique that makes even flat bottom prints easy to remove: heat the build plate to 130C and slide the spatula in under the soft ABS... it seems to work every time. The texture and torus shapes seem to be too much for the Customizer, causing script timeouts. Try opening the .scad file with OpenSCAD on your own computer, and have a little patience with the rendering times. Print Settings: Printer: FlashForge Dreamer Resolution: 0.18 Infill: 15% Notes: 3 shells, otherwise standard settings (3 top and bottom layers, all standard temps and speeds). If I print it again, I might go for higher extruder temp on the box - there was a little bit of layer separation, probably because of the size and cooling between layers. Hairspray on the build plate, check and recheck level before walking away. The first layer of print should give you a very good idea if you are at correct level. You might get away with printing it in PLA, but I would definitely recommend ABS for the lid. I printed both in ABS, they snap together very securely, I doubt that PLA would flex enough to go together with the current dimensions. How I Designed This I wanted a box... At first I was trying to make a custom sized box to just hold the components I'm planning, but that size was within an inch or so of my build platform limits anyway, so I expanded the footprint to near the build plate's limits and just give a little extra space inside to make wire packing easier. The round face corners are primarily to give a little style to the box, and also reflect the fact that I have big power supply bricks to go in the back and a Raspberry Pi that's not so big to go in the front. The honeycomb texture is an experimental idea to help with shrinkage problems and also make the big flat plates easier to remove at the end of the build. I might try changing the zip-tie bosses to cutouts from the walls in the future, but for now I thought that they would work better/easier being a straight pass through instead of trying to get the zip-tie to flex and push through a potentially "stringy" curved hole. The overhangs are all sloped to eliminate the need for any support material.
