Basic heat inserts press/jig

A simple heat inserts jig, which I've made for my cheap soldering iron. It consists of the following parts:1. Base - 1 pc;2. Rail - 1 pc;3. Slider (tool holder) - 1 pc, it has holes for M3 screws, but they were not needed with my soldering iron;4. Cap - 1 pc;5. Elastic band holder - 2 pcs, optional, but required if you use elastic bands;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;9. Elastic bands - 2 or 3 pcs, optional, needed only if you need the tool to get to initial position. 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. Important note: Using some kind of grease or oil on the rail is highly recommended. I'll be happy if you give me some feedback and show my your prints. Boost MeIf you like my model, consider boosting it so I can contunie to design mo
