mini/-malistic heat-set insert press

This is a minimalistic heat set insert press. Most versions of that are to big for my prusa mini or use lots of hardware or have lots of stuff to print.

Inspired by existing models I created my own version. It has 2 clamp versions.

1. a clamp for tools with ~21mm OD like Proxxon Micromot drill or TOOLCRAFT ST-50D soldering station. (that's what I use)
2. an adapter for clamps from the Stealth Press 1S - select desired soldering_iron_mount*.stl (currently not tested)

You can attach the whole assembly to a wooden board or use a table clamp with 8mm shaft (e.g. from bessy, see picture) to clamp it to a table.

The spring mechanism is inspired by this Heat Insert Press but I redraw it in FreeCAD to match my needs

Additional Hardware

• linear rail MGN7H with 150mm to 200mm length.
• 4x M3 10-12mm Allen screws
• 6x M2 10-12mm Allen screws
• 1x M2 8-10mm Allen screw
• 1x M2 nut
• 2x M2 washer
• 2-4 wood countersunk screws, when table clamp not used
• wooden board something like 130x130x13 mm, when table clamp not used
• table clamp with 8mm shaft, when not mounted to a board

when using Stealth Press 1S adapter you need additionally:

• 2x M3 10-12mm Allen screws
• 2x M3 heat set inserts

If you want to build this your intention is to use heat set inserts and screws, so except the linear rail you should have the screws and inserts already. I recommend buying always a set of screws and inserts, so you have always the right hardware available.

Print instructions

• print in PETg ! (clamp and springs needs material with a bit of flex)
• choose the clamp or the Stealth Press adapter
  • if SP adapter, then you have to print the desired soldering_iron_mount*.stl and the knob
• Springs: when printed with 0.4 mm nozzle, use 3 perimeters. 0.6 mm nozzle, 2 perimeters
• use orientation shown in the 3mf file

Assembly

• melt the M2 inserts in the base
• if SP adapter is used, then melt the M3 inserts into it
• screw rail to that inserts with 2 M2 screws
• take small M2 screw
  • put washer on it
  • put it in top hole of the rail
  • secure it with M2 nut
• screw clamp/adapter to the rail with the 4x M2 screws
• install the printed springs with 4x M3 screws
• if SP adapter is used, screw stealth press clamp onto it with M3 screws. Do installation like described there
• screw this assembly to a piece of wood
• install your soldering iron

If you use the provided clamp with the TOOLCRAFT soldering iron, you might notice (as shown in the picture) that the iron sits a bit awkwardly in the holder. It can wiggle slightly, so you’ll need to make sure it’s positioned perpendicular to the base. However, in practice I haven’t had any issues with it. I’m quite happy that with just one clamp I can securely use both of my tools.

Additional notes

I'm interested in your feedback to improve my stuff! So give me likes, post makes, comment and rate the print to show others and me how well it goes.
If you post a make, let me know which filament you use.

If you want to support me by donating a coffee go to https://ko-fi.com/antimaterie I would really happy about it. The money will be invested in all stuff regarding 3d printing to give more and better quality models.

In general my Prints are not for commercial use, but if you are a print farm owner and want to sell some of my stuff, please contact me.

Hope you enjoy my models.
