Laser Lifter - Ortur Laser Master 2 (20W) - 3D Printed
Introduction: Laser Lifter - Ortur Laser Master 2 (20W) - 3D Printed
After having the "Ortur Laser Master 2" for half a year now, it always bothered me that I had to raise the complete rack if the laser object was higher than 30-40 mm. Therefore, I looked around for a practical solution to quickly and easily make a height adjustment. Then I came across one or the other height adjustment, but they didn't seem optimal to me. So I started to design something myself and make optimizations.
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!
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.
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. 215
I recommend by about 5-7mm.
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!
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. A locking knob is integrated into the width of the lifter, so there is no restriction in terms of space on the x-axis!
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.

Remark: As all parts are designed to fit very precisely, it may happen that you have to rework one or the other part a bit with sandpaper and/or cutter due to different dimensional accuracy of the printers and the different behavior of the filaments.
