Introduction: Floor to Ceiling Clamp

This is an Instructable about how to make your own lightweight Floor to Ceiling Clamp.

A Floor to Ceiling Clamp is basically two poles which are being pushed apart by the force of a mechanism. This pushing force locks the upright poles between the floor and ceiling allowing you to easily mount almost anything anywhere in a room!

Here a few ideas I had for mine:

  • Shelving
  • Coat Rack
  • Room Divider
  • Clothes Line

I'm sure there are heaps of other uses, so now that you've seen how awesome these could be, let's build one!



  • Wood Saw
  • Metal Saw
  • Spanner
  • Power Drill
  • Drill Bits


  • 2x Sturdy Broom Handles, 25mm(1inch) Diameter, or similar
  • Threaded Rod and a Nut, I recommend M10, but other sizes could be used
  • Small amount of EVA Foam, 10mm thick

Also other household items like tape, scissors pens etc


Here's a link to the parts you will need to print out for this project:

They are designed so that any 3d printer can easily print them fast and with no support.

(Full printing instructions through link)


At this point you should have all your parts printed out so it's a good idea to double check their fit before we go any further. They should be a tight press fit. But if they are too tight give the broom handle end a bit a sand, too loose and you could wrap a bit of tape around the end.


Now things start to get tougher.

The two Coupling 3d prints should be attached to the ends of each broom handle, these are your drilling guides.

Like in the photo drill into one broom handle using a 9.5mm bit.

(This is so when the M10 Threaded Rod is placed in, it can be screwed in tightly).

Once the bit is as deep as it will go, take off the Coupling and drill deeper still (like in the second photo). replace the Coupling on the end when finished.

Repeat this process with the second broom handle and Coupling using a slightly larger 10mm bit.

(This end needs to firmly slide over the M10 Threaded Rod rather than bite it)

It is important to try drill these holes as straight as possible.


Time to attached the EVA foam to the bottom of the two Foot 3d prints.

This is necessary to give the push clamp some spring, which will hold it tighter and will stop it from damaging your ceiling and floor when setup.

Trace around the outside of the Foot on a piece of EVA foam, cut out the foam with scissors or knife, use double sided tape to stick it onto the Foot so it looks like the second photo.

Done? nice one.


Now you'll want to crack out the measuring tape for this bit.

My ceiling is 2.4(2400mm) high. So I need to cut down the length on my broom handles in order for it to fit.

I laid the two handles out end to end on the floor, leaving a small gap in the middle of about 30mm (this is where the threaded rod and nut will be later) by laying the measuring tape down beside it I could see I needed to trim one handle down by about 400mm.

Your ceiling height is probably different to mine, so do what you gotta do to get the right overall length.


First off you'll what to measure the depth of both of the holes. Then figure out what half the distance of that little gap you left between the broom handles was in the previous step. Add those numbers together and you've got the length your threaded rod needs to be.

For example my hole depths where 138mm and 110mm, and half the distance of the gap was 15mm.

So 138+110+15 = 263mm length

I used a hacksaw to cut mine with but a Dremel cutting bit is equally effective.


Take the threaded rod you just cut and screw it into the 9.5mm hole that you drilled earlier. Make sure you tighten it all the way to the bottom of the hole.

I held the threaded rod in some pliers to do this.

Screw on the nut and slide on the second broom handle so it looks like the second photo. Also attach those feet if you haven't already.

Step 9: SETUP!

Final step.

Bring the Floor to Ceiling Clamp upright in the position of choice by placing the a foot down on the floor and rotating it upwards. It should be able to go vertical without touching the ceiling yet, if yours does not and it's too long, no worries just cut a bit off one of the ends.

Now it's standing just below ceiling height go ahead and turn the nut counter-clockwise to push the upper pole in tight against that ceiling.

Remember don't over tighten it, as you could bust up the ceiling. Just tighten it till it's firm, the poles will probably still have some flex in them but this doesn't effect the overall sturdiness.

Ok cool. looks like you've now got a Floor to Ceiling Clamp.

Nice Job!

Thanks for the kind words D_mon and Seamster! You are right, this design can be easily made with a number of different methods and materials. In fact my early prototypes were built without 3d printed parts (see photos), but I used tools like clamps, a drill press and extra pieces of wood which may not be available to some people.

The aim of the 3d printed parts was simply to cut down hands-on build time and the amount of other tools and materials required (as well as provide additional structual support)

the 3d printed bits help to stop the wood from splitting too i assume, but its true, there are other ways it could be done too.
either way i love it, really nice idea! thank you!

This is brilliant! For anyone not wanting to go the 3D printed route, this looks like a design that could be cobbled together with pretty common tools.. Nice!

Very cool idea, thank you for sharing this.
