Summary

I had a special need for my laser setup to include a fixed metal table and the ability to permanently mount my rotary chuck. I didn't plan this in advance, but it worked out quite well. I thought I'd share back to the community that's helped me.

I found this inexpensive metal bed at home depot for $10. metal peg board. I needed a few brackets to mount it raised on the ortur x-frame rails. First attempt was the back brackets, which are custom to hold "this" peg board.

Unfortunately they didn't work on the side rails, so I created some new brackets for the side rails. The side brackets needed clearance for the y-axis travel. They also needed t-nuts inside the rail to attach stabilized. Turns out you could use these "side" brackets anywhere on the frame to mount any other kind/size bed.

I needed a cross brace between the sides to hold up one side of the bed. I just used some 1/2 aluminum angle.

On a complete tangent. I repurposed an old furnace as my engraving box. Worked out perfect. Even has a perfect (strong and quiet) extraction fan (pillaged from the furnace, - not the blower fan, but the exhaust starter fan).

How I Designed This

I used Freecad 0.21 on linux
Created a sketch (properly constrained the lines and points - the hardest part)
Turned it into a pad

Exported it as an STL file

Sliced it on Ultimaker Cura 5.5

Printed it on an AnyCubic Kobra 2 with SUNLU PLA+

Purchased some t-nuts from Amazon (https://www.amazon.com/gp/product/B086MKNYDS/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1)

I had to custom size (cut) a few m5 screws to properly fit the nuts, x-frame to the proper depth. (metric screws selection and options are limited in the US at most box stores)
