<p>First of all, thanks for the postings on Thingiverse of PLAY3Rone977, as well as the remixes by Crabe31350 and Spectra3D! This is a remix from all of them!</p><p>After looking at these models, I saw that they need quite a lot of space (y-axis). A relocation of the micro switch by about 15mm, is hardly possible without extending the two cables. I started the construction of my device with the aim to get a device that is as space-saving as possible, concerning the area of the y-axis and last but not least also the x-axis.</p><p>This laser lifter is only 4.2 mm thicker than the original laser mount. So the micro switch on the left side of the y-axis has to be moved backwards only accordingly! You have to test this. I recommend by about 5-7mm.</p><p>As for the rotating mechanism (crank or knob), different sizes of ball bearings were used in the existing models, among others. In principle, this makes sense! But since I prefer the crank variant and I had no idea for a practical and also visually appropriate implementation for a combination of a crank with a ball bearing, I decided to use a sleeve nut. This also works great!</p><p>Starting from 30mm distance from the edge of the heat sink to the surface of the base plate, the height can be adjusted upwards by approx. 80 mm.</p><p>A locking knob is integrated into the width of the lifter, so there is no restriction in terms of space on the x-axis!</p><p>Besides, it is not to be neglected that this model - in comparison to the others - needs less printing time and therefore less material. In addition, no supports are needed during printing.</p><p>Here you can find instructions on how to assemble it:<br>&nbsp;</p><figure class="media"><oembed url="https://youtu.be/Tr3SMDnANz0"></oembed></figure><p>&nbsp;</p><p>Material needed:</p><p>1x sleeve nut M6 (head Ø 19mm, hexagon socket SW 5, shaft Ø 9mm, shaft length 9mm)<br>1x Allen key SW 5 (optimal as crank)<br>1x threaded rod M6x120mm<br>2x nut M6<br>1x Phillips screw M4x25mm<br>2x nut M4</p><p>2x 2,6 x 9,5mm self-tapping screws<br>1x cable tie</p><p>Required stl. files:</p><p>LaserLifter_guiderail_left.stl<br>LaserLifter_guiderail_right.stl<br>LaserLifter_lasercarrier.stl<br>LaserLifter_liftertop.stl<br>LaserLifter_lockingknob.stl</p><p>Have fun with the LaserLifter!<br>Stay safe!</p><h3>Print instructions</h3><p>Printer brand:<br>Prusa</p><p>Printer:<br>Prusa Mini</p><p>Rafts:<br>No</p><p>Supports:<br>No</p><p>Resolution:<br>20</p><p>Infill:<br>20%</p><p>Filament brand:<br>Prusament</p><p>Filament color:<br>Galaxy Black</p><p>Filament material:<br>PLA</p>
