Introduction: Spring Loaded CNC Pen Holder
Hello! This instructables will show how to make an inexpensive yet very effective pen holder which will help maintain even pressure across the printing/machining surface of a CNC machine. I was inspired by this instructable by ähöüokul :
However, I couldn't find the required bits at the time. And so, instead, I searched for an alternative. What I have come up with is an unintentionally steampunk looking, pen holder made from widely available plumbing supplies.
Step 1: Tools & Materials
You'll require only a few fairly basic tools:
- Pipe cutter link or you could use a hacksaw
- Glue gun
And the materials:
- 15mm Ø copper pipe
- 1/2" Brass hex nipple link x 4
- 1/2" Flanged brass end cap link x 1
- 1/2" Brass socket link x 4
- Duct tape
- Two part epoxy
- Fine liner pen of your choosing
- Spring from a disposable biro
These bits should cost you around £10 and are available from most hardware stores.
Step 2: Assemble
I have made a short video going through the steps I took to build this holder. If you have any questions please leave me a comment and I'll do my best to answer them.
