New: Now also for the Prusa MK4 (MK3.5 and MK3.9 too)! Let me introduce you to the Bulletproof Wide Body for the Prusa MK3 and MK4 series!A machine that runs and runs and runs gets a look that is equal to this.In December 2020 I released the Ultimate Prusa Casing, the response was tremendous. For me it was clear, there must be a successor and here it is.The body kit for the MK3 and MK4 series is a purely optical upgrade which is designed solely to ensure that you have even more fun with your printer! It is a solid model which, when mounted correctly, does not produce noise or increase the footprint of the printer.Important: The parts of the MK4 version are not compatible with those of the MK3 version (and vice versa)! Due to the new display cover, all parts had to get modified. I recommend to reprint the display cover from the same filament as the rest of the parts, you can find the cover here.As I don't own an MK4 yet, I haven't been able to validate the display button yet, it might sit a little too high. However, the other files were test-printed and tested on an MK4.Note: A little mistake has crept in which was fixed on 02/22/24. The traverses for the MK3 are not compatible with the parts for the MK4, as the MK4 traverse has become a bit slimmer.For the assembly you only need a few screws, a list is given below.I highly recommend printing this case out of a matte PLA, it will improve the visual quality immensely! A 750g roll of filament is sufficient for this, the entire model can be printed without supports.Print Instructions:I recommend a layer height of 0.2mm, the largest parts are the two side parts, to save time it is worthwhile to lower the infill to 15% and from a height of 10mm to 5%. I printed the case with 3 perimeters, but two should also work.You don't need any supports for the print.(MK3) There are four different traverses, three different logos and one without. Also two variations of the knob for the LCD cover, you can of course use any other knob.The SD card gets a handle that makes it much easier to use. Normally it's enough to just push the card in, but if it's too loose you can stick a piece of tape to the card to slightly increase the thickness.Display cover (MK3):I've uploaded the CoverV2_Improved-mounting. The LCD is mounted with 4 M3x10mm screws instead of the classic two screws, as this caused vibrations in some cases.You have the LDO OLED screen? Click here for the OLED version of the display cover!On top of that I recommend to mount this baseplate for the printer with the bodykit.And if you want to go even further you can also add this Einsy Case with this doors I designed for the body kit.Required parts:4x M3x10-20mm (side parts to mid parts)2x M3x8-15mm (mid parts to traverse)4x M3x12-14mm (T-nut to side parts)4x T-nut for M3 screws (To attach to 3030 extrusion of the printer)2x M3x10mm (For CoverV2. Improved mounting of the LCD by two extra screws)Assembly:You can find photos of the assembly above at the pictures or at the files as PDF.1. change the display cover. Follow the instructions given in the printer assembly manual.2. screw a middle part to the traverse.3. screw the just connected parts to a side part.4. screw the T-nuts with about 2 turns to the side parts5. place the connected parts on the printer, then attach the other center part, followed by the other side part.6. tighten the screws with the T-nuts in the 3030 extrusions of the printer. Make sure the T-nut has turned and is pulling the side parts to the frame. Also make sure the casing is lined up properly.7. post a Make of your printer in its new look. ;-)I would be very happy about a like or a rating if you like this project, also take a look at my other designs!Follow me on  Twitter for regular updates and more!Since people often ask about it: What other modifications are on the printer in the photos?MK3 Bear X-axis from GregsaunLED lightbar from In3DSpaceMK3 BaseplateMK4 Baseplate from Cal'sTechConceptOpenable Z-axis mountOLED Cover whith the LDO OLED screenDelta P-Fanduct for Bear X-axis from teookieOpenable Y-Rod mountExtruder visualizerYZ Case from Carter and this additional door designY-Axis Motor Mount Ultra from OurAngryBadgerNote: Since the question came up recently, the license states that you may not use this model commercially. For me it's ok if you show the photos or the model to your audience, even if you make money with it as long as you name me as the creator and link to this page. You are of course allowed to mount this model on your printers if you use them commercially in a print farm. You are not allowed to sell the files or the printed model itself.
