Duet 2 Maestro case for Prusa Bear v2.0 and up

prusaprinters

<p>This is a complete redesign of my Prusa Duet enclosure (<a href="https://www.prusaprinters.org/prints/24757-duet-2-maestro-case-for-prusa-mk2-mk25-or-mk3">https://www.prusaprinters.org/prints/24757-duet-2-maestro-case-for-prusa-mk2-mk25-or-mk3</a>) made to fit a Bear frame.</p> <p>Features, improvements and other changes:<br/> 1 ) The cable management features were removed to make the encloure not stick out the back of the printer, decreasing it's overall footprint and thus making it easier to enclose.</p> <p>2 ) The door slides in from the top and does not need screws to be held in place, which makes it even easier to access the electronics inside.</p> <p>3 ) The door is again on the outside of the printer, which makes working on electronics much easier than the stock Prusa enclosure</p> <p>4 ) The enclosure is mounted to both the vertical and the horizontal parts of the Bear frame, which makes it quite a lot stiffer.</p> <p>5 ) The ammount of material used and the print time were reduced by about 40% compared to my old enclosure</p> <p>STLs, STEP files and original Solidworks files are all provided. main.SLDPRT has a bunch of build errors, but should work anyway. If anyone wants to correct these errors they are free to try, I have failed in that respect.</p> <h3>Print instructions</h3><p>0.4mm nozzle<br/> 0.2mm layer height<br/> 3 perimeters<br/> 5 solid layers on both top and bottom<br/> supports off<br/> The 3MF file should have the correct settings already.</p> <p>Material should not matter too much, I used PETG. Try to avoid using PLA for the main box, it will be mounted right next to the bed which can be very hot (up to 110C).</p> <p>Non-printed parts needed:</p> <p>To mount the case:<br/> 3 M5x8 screws (my Bear frame came with a few extras so I used those)<br/> 3 M5 tee-nuts - the srew holes were carefully placed to allow inserting the nuts without disassembling the frame.</p> <p>For the cable holders:<br/> 4 M3 square nuts<br/> 4 M3x12 srews (mine were extras from the Bear again, M3x10 should work too)</p> <p>To mount the Duet:<br/> 4 M4x10 screws<br/> 4 M4 nuts<br/> 4 plastic washers (they come with the Duet) to isolate the srews from the PCB</p> <p>NOTE:<br/> MOUNT THE CASE TO THE FRAME BEFORE YOU PUT THE DUET ISIDE.</p> <p>Remove the end plates as shown on one of the photos, insert two tee-nuts from the top of the z axis and one from the side of the printer. Locations should be obvious from the printed part.</p> <p>This has to come first, you might not have enough room for tighenting the screws once you mount your Duet.</p>
