The choice of Prusament is because of is consistency between batches and different colors.</p><p>I used Prusa Slicer and an original Prusa MK3S with the powder coated bed for the 3d printed parts.</p><p>All the stls are in the right orientation.</p><p>The front and back plate is intended to be laser cutted on 3mm acrylic (files included), but can be 3d printed as well, so I’ve included a stl file for them. Prints the following parts:</p><ul><li>1x nixieLDL_v2_Body_3mm: Prusament PETG, Preset 0.2mm SPEED, no supports, 3 wall</li><li>1x nixieLDL_v2_Buttons: Prusament PETG, Preset 0.2mm SPEED, supports on build plate only</li><li>1x nixieLDL_v2_BackPanel_3mm (if not laser cutted): Prusament PETG, Preset 0.3mm DRAFT, no supports</li><li>1x nixieLDL_v2_FrontPanel_3mm (if not laser cutted): Prusament PETG, Preset 0.3mm DRAFT, no supports</li></ul><h3>&nbsp;</h3><h3><strong>Part List</strong></h3><ul><li>Printed parts</li><li>Laser cutted parts (not necessary)</li><li>1x PCB kit (with the included screw and stand-offs).</li><li>4x IN-12 Nixie tubes</li><li>…x Haribo bears (not necessary but highly recommended)</li></ul><figure class="image"><img src="https://github.com/lorenzo-dl/NIXIE_LDL_CLOCK/raw/main/images/img7.jpg" alt=""></figure><h3>&nbsp;</h3><h3><strong>Assembly instruction</strong></h3><p>With a soldering iron solder the tube socket pins and the digit separator bulbs (included in the kit).</p><p>Insert the front panel on the body and make sure it is well secured by the clips on the printed part. (See them on the image below)</p><figure class="image"><img src="https://github.com/lorenzo-dl/NIXIE_LDL_CLOCK/raw/main/images/panels_clips.PNG" alt=""></figure><p>Now get the back panel, insert in every 4 hole a screw and secure them in the back with the smaller type of stand-offs that are included in the kit, insert the pcb now and pay attention that the buttons and the usb port are on the right side.</p><p>Connect now the bigger stand-offs and on top the medium ones like in the photo below.</p><p>Place now the buttons in the holes presents in the main body, and snap in place the front plate.</p><p>Insert very carefully the previously assembled block with the pcb, the back plate and all the stand-offs in the main body, the usb/button side need to be in the right orientation.</p><p>Secure now the whole assembly with 4 screws on the front plate and you’re done.</p><p>Happy printing and enjoy your new clock.</p><figure class="image"><img src="https://github.com/lorenzo-dl/NIXIE_LDL_CLOCK/raw/main/images/render_lines.png" alt=""></figure><h3><strong>licensing and contacts</strong></h3><p>Thank you for reading and your interest, if you want more details feel free to visit the project <a href="https://github.com/lorenzo-dl/Pixie_6digit_clock">GitHub page</a> or contact me on Instagram <a href="https://www.instagram.com/delucalabs/">@delucalabs</a>.</p><p>This design is free for personal use, please don’t sell an exact copy of this.</p><p>I sell some assembled clocks, if you want to know more contact me on Instagram.</p><p>This design is licensed under a :<a href="https://creativecommons.org/licenses/by-nc/4.0/">Creative Commons (4.0 International License) Attribution-NonCommercial</a>.</p><p>If you find this design useful, please consider a donation for supporting new designs and further development.
