Large brick chest

prusaprinters

<p>This is a remix, I made several adjustments to the original model, I mention the main parts:</p><ul><li>Adjusted the scale to actually x10</li><li>detached the hinge part and the handles for less use of support material</li><li>modified the geometry slightly, mainly chamfers and fillets for better printability</li><li>adjusted the size of the studs (were slightly too large)</li></ul><p>Since I split it into parts, they obviously have to be joined somehow, I decided to use M5 countersunk bolts and threaded brass-inserts for that purpose. The holes are made for the ones I had on hand but it should fit for most heat-inserts (I used some cheap ones from amazon).&nbsp;<br>You additionally need:</p><ul><li>4x M5x25 for the handles</li><li>2x M5x40 and</li><li>2x M5x30 to attach the hinge part to the lid (35mm and 25mm also work)</li><li>2x M5x35 as hinge</li><li>2x M5 lock-nut to secure the hinge-bolts</li><li>8x M5 threaded brass heat inserts</li></ul><p>For the printing part, I used:<br>PLA (and PolySupport as dedicated support-material),&nbsp;<br>0.4mm line width,&nbsp;<br>0.3mm layer height,&nbsp;<br>2 wall perimeters,&nbsp;<br>3 top- and bottom-layers,&nbsp;<br>15% infill (with 1 gradual infill step, so 7.5% for most of the part),<br>since it is a pretty large part, I recommend using a brim for better adhesion, especially at the corners.<br>I used infill modifiers to print the area around the holes for the treaded inserts with 100% infill (I used a simple cube with 15mm edges as stencil and placed it at the holes). The mounting holes print fine without supports inside, but you'll have to rework them with a drill since they won't be very round at that layer height (the ones that get heat inserts are fine without rework).&nbsp;</p><p>It is pretty large (320x160mm) so it took about four days to print and used a little more than 1kg of PLA.</p><p>By the way, the floor of the crate fits regular brick-plates 16x36 studs wide, in case you want to build some “lego-ception” inside.</p><p>If you like it, there's also <a href="https://www.printables.com/model/231577-large-brick-barrel">a large barrel</a> :).</p>
