To make the images more viewable, I did not show a stop plate.
You should use a stop plate to protect your bottom surface.
4 component mounting shoes:
I like to use a standoff that is a bit longer than the material is thick.

DCM?
I guess it's a solvent for welding plastic.
DCM, or ‘Methylene Chloride’, or Dichloromethane (takes 15 seconds to weld acrylic).
If ABS plastic is used Acetone works.
MEK works but smells bbbaadd.
You could use 5 minute Epoxy glue.
You can try PVC and ABS glues from the hardware store.
Or double sided foam tape if the plastic nut is sufficiently large.

Methylene Dichloride is sold here, in the UK, under the trade name "Plastic Weld".
I keep mine in the fridge, to stop it evaporating.
MEK = Methyl Ethyl Ketone. I don't mind the smell. It's not as bad as Acetone.
Some of the higher Ketones have quite pleasant smells, one has a distinctive 'pear drops' smell.

What bottles do you use to store your DCM?
Would you show an image of the inside of the cap.
What do you tell your spouse when you put the solvent in the fridge? 
I think Weld-On 4 is DCM in the USA.
DCM in Canada can be bought under the name ‘Fast Bond’.
I do a lot of plastic construction with DCM.
Hobbyists often use this applicator to weld with DCM.

I think Weld-On 4 is DCM in the USA.
I store it, upright, in the bottle it came in. 57ml (2 imperial fl oz) in a brown glass bottle with a 'childproof' cap, the type used on medicine bottles. I bought it from a model shop.
I've seen 500ml cans of it, but I don't know where to buy them and don't use it often enough to justify buying that much.
As it has minimal smell and doesn't evaporate in the fridge*, my wife hasn't complained about it in the year or so it's been there. 
- I suspect that there is a slight negative pressure in the bottle when it's at 5oC.
If it was causing a nuisance, I could try putting it in the freezer, but don't know if the bottle would withstand freezing.
I usually apply it with a modelling paintbrush, the type with only a few hairs. Only a very small amount is needed, as it has low surface tension and capillary action flows it along the join.
Do the caps on the bottle have a polyproplyene or aluminum tape seal?
DCM freezes at -97°C so the freezer should work.

Inside the cap is an aluminium foil disk on a slightly compressible substrate. It appears to give a perfect seal against the glass bottle.

My freezer only gets down to about -20oC, so no chance of it going solid.
DCM is the basis of many commercial paint strippers, so be careful!

Agreed.
However, using DCM in these kind of applications, we are talking about 4 drops at a time.
I do highly recommend a bit of protection

3D work platform.
Make an adjustable work surface for your work bench.
Aim the platform by adjusting pitch and yaw.
Two C clamps hold the tool’s base to a bench pin or use the 4 holes in the swivel base to attach to a wooden board.
Attach cameras, sensors or other equipment.
Also great as a soldering platform with adjustable positions.
Use it for holding a powered PCB while measurements are taken.
The board can be turned to a desired position to get to test points.
You need:
- 4” X 1 3/8” Locking swivel caster wheel. ~$20.00. Source Or Home Depot
- Two aluminum 1” X 1” angle brackets.
- Four M2 nuts, screws. standoffs and washers.
- Four #6 self-tapping screws.
- 1/8” aluminum ‘first story’ with corner holes to attach other surfaces.
- FR4 PCB ‘second story’ surface to allow clamping
The wheel lock, locks the ‘pitch’ axis.
A bottom front screw locks the ‘yaw’ axis. Screw pushes a pressure plate against the swivel base bearing bell, locking it.
Leaving the two locking controls a bit loose, allows for tuning, or you can lock the controls completely.
Two angle brackets are spaced so the wheel can fit in between.
Four self-tapping screws attach the brackets to the wheel’s sides.
You can effectively use your drill press to cut straight strips of material.
A carbide CNC routing bit, a jointed routing fence and a sled to hold the work is all that’s necessary.
The 'work' is stuck to the sled with double stick tape.
The overhang minus the diameter of the bit will be the final width of your strips.
Let's say you want a 1 inch strip of material.
If the cutting bit is 1/8" you must have an overhang of 1.125"
This method is faster and gives a neater edge than using a saw.
Always use eye protection and wear a dust mask when cutting materials.
Every workshop should have a have a pair of digital calipers.
They are very inexpensive nowadays ~$25.00.
Even the cheap ones are good as they give repeatable results.
My old vernier calipers were thrown away years back.
If, however, you need to send measurements to others, consider using a micrometer.
You might want to carry a pair in a holster like they did in the 60s with slide rules .
If you haven’t used a pair of calipers, these images might be of interest.
