Description

Update 26.01.2025: 

 

  1. Added two hooks for elastic bands, to allow return to initial position.  You will need to glue them with strong adhesive to the top of the cap and the back of the tool holder.

  2. Added TPU ring for the handle/wheel for better grip. You will need to print it and slide it over the wheel.

Those part are not mandatory, but make handling the jig more coonvenient. I'll add them as STLs and separate print profiles.

A rack gear heat inserts jig, which I've made for my cheap soldering iron.

Parts list:
1. Base - 1 pc;
2. Rail - 1 pc;
3. Rack – 1 pc;
4. Spur gear – 1 pc;
5. Spur gear shaft – 1 pc;
6. Spur gear shaft cap – 1 pc;
3.  Slider (tool holder) - 1 pc, it has holes for M6 screws, but they were not needed with my soldering iron;
4. Rotary handle – 1 pc;
4. Cap - 1 pc;
6. Box (bottom) -1 pc, optional;
7. Box tray - 1 pc, optional, can be used for storing heat inserts and soldering iron adapters;
8. TPU feet for the bottom - 4 pcs, optional;

You can use the jig perfectly fine without the optional parts. Nevertheless I think it will be more functional and good looking with all of them.

Notes: 
1.    Using some kind of grease or oil on the rail and spur gear shaft is recommended, but not mandatory. 
2.    The moving parts are designed with medium tolerances, but not the smallest. This is to ensure that even if your filament is not properly calibrated, the assembly should still work. 

3. The connection between the spur gear and the gear shaft was intentionally made tighter. If it's too tight you might wanna grind a bit only the inner surfaces of the spur gear. The wheel, spur gear and shaft can be aligned for use with left or right hand.

I'll be happy if you give me some feedback and show me your prints.

Great design. Nice project to work out tolerance, mechanical function, color sequencing, multi part printing and sequencing, fit, and finish. I enjoyed working this project immensely and really appreciate that it is a functional part of my tool kit now! Thanks!

Thank you so much! I encourage you to try the upgrades - rubber band hooks and TPU wheel ring. Those make it even better. Looks so good in red nad black.

The device is exceptionally stable My soldering iron could be firmly clamped in it with two screws The height adjustment wheel turns smoothly and the dial engages perfectly with the rack Everything including the TPU feet printed flawlessly I secured the feet to the well-fitting recesses in the base plate with super glue Thank you for this remarkably well-conceived and superb design

Printed great, looked great, but the tolerances were way too tight and could not assemble (Bambu PLA Basic) Shaft snapped as well as the cap. Could not get tower to insert into base without lots of sanding once inserted the holder for the iron would not slide up and down.. Might try again another time after tweaking the settings.

I'm sorry to hear that! It shouldn't be so tight. I thought it might be filament calibration issue, but since you're using Bambu filament, that shouldn't be the issue. If you need some of the parts with bigger tolerances, I'll be happy to provide them to you. Just inform me which parts you need.

Nice looking peace of equipment. Could be a drill press. Three more plates and it will be all mine, oops, I mean all done.

Thanks! Dont't use it as a drill press though, because it is calculated for small loads. It won't be strong enough for other than what it is intended for.

great tool. Wish it showed how long of bolts are needed. the only problem I had, which are my issues, are 1 corner lifted during printing and the vertical arm didn't like to print at the back and I had to move it to the middle of a new plate.

I haven't had ussues with lifting, but if you do, you may try to use brim on that component. I have a P1s and printing the arm at the back of the plate went fine. Still I don't know how it will go with other models. Considering the length of bolts needed - I have missed to add it to the description, but I'll add that info later. Thanks for the feedback!
