Longer Ray5 mini S improvements

I did some small tweaks to my little laser engraver and made the parts for you to download:

1) Hose adapter
The stock fan is not enough for sucking air through an extraction hose.
I removed the fan and milled a 100mm hole in the back of the case with my CNC router.
A hose adapter for a 100mm hose was printed and it attaches through the 4 holes, already in the enclosure.
The stock fan screws can be used, but because they would extend a little too far in the casing for my liking, I printed four 8mm stand-offs. (Ideal length of the screws would be 12mm without the stand-offs)
If you plan to enlarge the stock vent hole, you can use the "Hose adapter center point jig" to align you cutter.

2) Feet
I removed the bottom of the casing as many of you will do I imagine.
With that you also remove the feet, so I made four identical feet which can be attached with the stock screws.
In the middle of the round feet there is a little hole for if you want to screw in a little rubber foot for example, but I did stick on some adhesive foam stickers.

3) Feet risers
The risers allow you to raise the machine up for engraving parts that are higher than a flat piece of stock.
The risers are 40mm are a friction fit onto the round feet listed above. They print without supports and if you did screw in some higher rubber feet, there is room for those in the hollow part of these risers.
The risers can be stacked, so 8 of 12 cm is also possible

4) Door bumpers
When the door of the cabinet is opened all the way, the hinges bare all the weight of it which could make the acrylic material crack. I made two simple bumpers to be mounted with the stoc screws so that the door rests on those bumpers when opened.

5) Focus block
I designed a little focus block to be used with or without the red protective shield attached to the head.
Standard focus height is 2mm with the shield attached, and 25mm without the shield.
There is one little step down (-1mm) for those cases you want to lower the focus a little.
A standard round 6x4mm magnet can be pressed in so you can attach it to the machine and never loose it.

Note: Photos show parts printed in ABS with 0.28mm and 0.6mm nozzle (focus block printed with 0.2mm layers)
