IKEA Lack Enclosure

thingiverse

This is my IKEA LACK 3D printer enclosure, built from two tables and designed to handle printing materials that would otherwise be difficult to print due to their size or weight. I created this enclosure because most others I found lacked sufficient height for placing a concrete paver without causing the filament to bend or snap when printing tall objects. I chose to make my own enclosure since it needed more height than those available online, and I wanted a printer that could handle large prints without problems. The stl files are designed with precision in mind, taking into account any tolerances that may be present during 3D printing. One thing to keep in mind is that the IKEA LACK legs aren't as square as they should be, so even if you achieve absolute dimensional accuracy, there's still a possibility of parts not fitting perfectly. However, this isn't usually a problem since most people are close enough and don't need perfect alignment. I've made some changes to the design over time based on user feedback and my own testing. On March 11, I was able to print out the modified stl files and check if they worked as expected, which they did. The fix introduced into the Middle Spacers was successful, resulting in a square enclosure (444mmx585mm). Now it's time to order polycarbonate panels. In my previous update on March 8, I discovered another tolerance issue when printing the Middle Spacers. This resulted in a difference of 2mm between the legs on the lower and upper side, which would cause the sides/door to be trapezoid-shaped. I also made the holes for the brass inserts wider and deeper as suggested by SuperRoach. On March 7, I changed the way the leg extensions are mounted to the top LACK legs. The BOM (Bill of Materials) and assembly manual were updated accordingly. I found that the pressboard material on the LACK's legs gets damaged quickly if you unscrew the leg extensions later on. Finally, on March 5, I fixed a small missalignment issue with the holes in all "Middle Spacer" parts. The hole for the woodscrew that connects the leg to the table was not centered.
