I’m trying to design this printer stand that goes under a big desk wing. There’s a big photo printer up top and a regular ink jet printer in the middle. The remaining space below will house a drawer for various papers and ink storage. The whole thing is on fixed casters so it can be pulled out to use the big photo printer, and I want to make the center shelf on full extension slides so I can pull the regular ink jet printer out when I need to use that (the paper in feed sticks up out of the back).

I’m really getting stuck on the details. The cart is 3/4 plywood and I was intending to put a face frame on it that wraps around the sides for a nice standalone “cabinet” look. What’s getting me right now is the sliding shelf. I could use a regular side mount ball bearing full extension drawer slide, but the problem is those are ~1.5” tall and the shelf is only 3/4” thick so it would interfere with the drawer on the bottom. I could just hang the face frame lower on the sliding shelf, but that really makes my drawer pretty small, and I can’t make the top shelf any thicker to match or my printers won’t fit under the desk (and leaving it at only 3/4 tall while everything else is 1-1/2” would look off).

I saw some thin groove slides which looked good and still held probably enough weight (~20 lbs), but they aren’t full extension, which kind of defeats the purpose. I would prefer to leave it as a fixed shelf.

Any thoughts on this?

I thought about adding some 1.5” “runners” down the left and right side to sort of hide the slides. Maybe that’s the way I’ll have to go.

It’s kind of hard to put into words. But here’s what I came up with. Basically a box around the slide on the shelf.

Do you really need full extension, or can printer be sitting near front; so can use partial extension bottom mount drawer slides?
There are European bottom mount slide that claims to carry 100 lbs, and only require 3/4 inch panel thickness. Commonly found on cheap particle board furniture from Walmart, but they work pretty well as long as screws are in plywood and not wood dust pressed into board shape.
If need more extension to access the printer, make the shelf depth oversize for printer.
Can also make shelf smaller than cabinet depth, and offset the shelf to front of slide so that entire shelf extends.
Best Luck.

I think you found you solution with the boxed in edges.

Now you know as soon as you finish it and subsequently need to replace the printer the new printer won’t fit. LOL
That happened to me with a large TV cabinet I made and then the TVs changes shape and size.

Unfortunately the printer needs to be full extension because the paper load tray sticks vertically out the back. I’m using it in a crammed space right now and it’s fine, but if I could pull it out to use it, it would help a lot. If I can’t get the printer shelf to pull out all the way, I’d rather just not bother with all the details and just dado the shelf in place. The drawer, on the other hand, does not need to be full extension, but it’s not complicated and wouldn’t really solve anything making it 3/4 extension or similar.

I thought about a shorter shelf depth, that could work with something like this: http://www.leevalley.com/us/wood/page.aspx?p=40591&cat=3,43616&ap=1

Haha, yeah that crossed my mind… this printer is old too, but still kicking. I guess the silver lining is this one sits pretty tall at 10 inches with an auto document feeder/ scanner on top. I’m sure I could get a new cheap one smaller than that.

Hmm… Even with full extension it looks like it doesn’t come out far enough to expose the back of the printer. It might even need to be an over-extension slide, haha.

This printer does have a pretty big lip on the front of it though that could probably overhang a little. The box in the drawing above is just overall dimensions. If only I had just a few more inches in every direction…

(excuse the dust…)

Just had a thought – the printer cart is about 7-8” shallower than the depth of the desk top. I was planning to make a wire hanger hung from the desk top behind the cart, but I could still make it a couple inches deeper and use 20” slides instead of 18” slides. That would push the printer out a tad further with full extension slides. I don’t really want the thing to feel huge and clunky is all, but it could work.

Have your say...
