This is a mounting system for a 40/50w 50mm diameter CO2 Glass Laser Tube to fit a China Blue/White Ebay 50w (really 40w) Laser CNC Engraving cutting machine.
I designed this from scratch, however I took cues from the following things so I wanted to give source idea credit:
Neither seemed logical. Both mounted facing in which means removing the whole bracket to remove the tube.
My goals with this design:
- Fit my machine and tube
- Solidly support tube
- Can be installed without modifying the machine
- Can be installed without being an octopus
- Tube easily installed and removed
- Easy to adjust tube position at any time
- Use mostly common materials (preferably what I have on hand)
- Easy to reproduce
- Can be adapted for additional tube sizes (upgrades later)
I started out with notches for some plastic tubing, however the tubing I had was too stiff and I was afraid it would put too much pressure on the glass tube so I used some open cell foam instead which worked just as well. I left the notches in the ring for those who may have better tubing on hand.
The inner ring has a 54mm opening which allows for 2mm room on all sides of a 50mm tube for whatever padding/tubing you choose to employ.
You will need 6 4mm x 4.6mm heat sets: https://www.mcmaster.com/#94180a351/=17jj3tx
The rest of the hardware is all cap head 4mm screws and nuts commonly available at local hardware stores.
Here is a video of the 3D:
I rendered the video with transparent materials of different colors to show how the pieces fit together.
This was designed to fit in my Blue/White China laser. I do not know if it will fit other laser machines. If you do print it and it does fit your machine, let me know so I can add the info to this description and keyword tags for others to find.
I printed mine in PETG using 3mm layer heights. However I feel ABS and PLA are also just as suitable for this print.
