Some super cheap soldering iron stand is very faulty and dangerous to use. Mine happened to be that one, and it came with beginner's soldering package. (This one from Walmart seems very much identical.) Spring part on this model is angled at 30 degrees. (I should've made this parametric but I didn't have enough plan/skill, but I can share Fusion 360 data if anyone wants them.) Cap (socket) has inner diameters of 20.0mm and 15.5mm respectively.
Warning: While this marginally increases safety by avoiding the soldering iron to swing around, this upgrade does NOT ensure the safety hazard risk in any ways. Effectivity varies by the choice of material (recommended to be printed in highly heat resistant materials) and secure adhesion, etc. And this model does NOT guarantee the safety and I will not be responsible for any hazards and damage it may cause to you. Please use this with caution!
The problem I'm solving with this are:
- Stabilize the soldering iron holder part from swinging around
- Add insert cap that holds the soldering iron at the center of the springy part, so that hot part of the soldering iron would not add heat to the stand through metal parts (to prevent printed parts from melting)
What you need other than printer
- Adhesive materials
- [Stabilizer] I used foamy double-sided tape (It has rectangle recess for the tape beneath the stabilizer. Rectangular parts demension is 17.0 x 22.5 x 0.8. But you may use other material of your liking.
- [Cap] Print itself likely may not produce enough friction for the part to stick to the springy part, so I recommend using glue gun or something. (Doesn't look pretty but it's far better than nothing!
- Something to tighten nuts
Assembly Instruction
- Print parts and disassembly the whole stand
- Add one nut to the spring's screw, and find the desired depth by testing the fitment with stabilizer. The base of spring should sink into stabilizer's groove so it won't swing to the sides.
- Adhere the stabilizer to the base plate
- Tighten the nut from beneath the base plate
- Add cap to the spring (and add adhesive material if you want)
