Zip Tie Raspberry Pi3 Case for fastener free mounting to side of Ikea Lack end table

thingiverse

This is a Raspberry Pi3 case designed to be assembled with Zip Ties (or string, or whatever) instead of screws. The legs have pockets to fit the zip tie heads for a clean look when properly assembled (see pics). It is 3 parts - case lid, case base, and case legs. The zip ties I used are roughly 15cm long (total length) have a buckle (head?) roughly 4.5mm x 4.5mm, and have a strap 2.5mm wide. I know these as "the little zip ties" - as I do not regularly see smaller zip ties (these are the smallest common zip ties is what I'm trying to say). Assembly works best if you take it one layer at a time. Start with the legs. Insert the zip tie from sides of the legs. When you get all four through the first layer, install second layer, then third. Then secure the zip ties and push the heads into the recessed in the legs and cinch the straps before cutting the excess strap length. Handy Tip: curl the ends of your zip ties before trying to put them through the slots. The radius of the curves is tight and it can be difficult to push the zip tie through them if the zip tie doesn't have a little curl at the end. The legs are designed to slide onto an Ikea Lack end table and be snug, but easily removable. The legs are about 25mm long. You will need to rotate the lid and legs in your slicer for support free printing. Has a few instances of bridging (the SD slot, the power connector, and one on each leg), but it printed fine for me with no supports with the logical rotation of the parts (top of the lid and bottom of the base flat on the printer bed). The shell is 2mm thick for a sturdy case. It is a tight fit on a Raspberry Pi3 with only about 1.5 mm of space around the PCB.You could not have a smaller and more robust case. It does not have dedicated slots for the GPIO, camera or screen ribbons, but I suspect the camera ribbon could be put through the cooling vents on the lid (don't hold me to that). Also included .STP files for easy remixing - if you want to add dedicated camera or screen slots, GPIO access, visible LEDs etc. I have models for a lid to use 3mm flush head screws, but 3mm screws seem to require a bit of enlarging of the holes in the Pi's PCB. I can upload those if anyone wants them, but I like the idea of using Zip Ties and am not going to recommend that anybody take a knife or drill to their Raspberry Pi's PCB. This is my first all original design for 3D printing. I've only been 3D printing for about a month, so let me know if there are any problems. I'm open to requests for alterations or variants.
