Friend gave me nice idea about a trash bag holder and after he left it was time to draw a 3D model of it. I tried to reduce amount of plastic and after few prints this came out... Since I'm working on my new workshop, I just draw new holders for tools, broom, airbrush, screwdrivers, bit wrench and other stuff. I also added holder for dolce gusto capsules that can be used also in workshop if capsules are changed with printed cups or modified capsules from dolce gusto coffee.

My goal is to add more holders in future, when I will need them. But if anyone wants to customise holder, I added step file for small and big holder.

Thanks goes to https://www.azurefilm.si/ filament maker that supported this and my other projects.

Some of files need to be rotated in slicer for better printing experience.

Attaching Base and magnetic cups and assembly other holders

For attaching base parts on wooden board I used Philips wood screws with flat head, but If anyone want to use holders on wall, just use small screws that can fin in to hole. I made 6 holes in smaller base part, two are bigger for mounting on concrete or dry wall boards, 4 are for attaching on wood. For wood use 2,5x12 or similar size flat head wood screws, for attaching to wall, use up to 3,5mm and 20-30mm long screws with wall screw anchor (5mm or 6mm anchor will be more than enough). Also you can use double side tape if you want to attach them on plexiglass or glass (just clean surface for better adhesion).

For using screwdriver, wrench or dolce gusto holder have to use 2 universal holder adaptors with M3x20mm screws and M3 nuts. Just insert nut into hex hole on universal holder adaptor and put screw trough thole on top of holder and screw together with adaptor.

Attaching trash bag to holder is very simple job to do. Just make sure some bag is over the holder and then insert holder with bag into base part. just press it to get tight fit and that's it. With bigger amount of trash, bag will be secured in holder, same is with other holders. But if you want to secure holders from not falling out, some Glue or small screw can be used. Just add little drop or CA or other plastic glue or drill small hole that goes trough base part and holder and secure it with pin or small screw.

Dolce gusto capsule holder can also be used in workshop, just use cups. Cups can be used with magnets or without them. Holes are made for round magnets 6x1mm ( eBay, amazon, aliexpress or local store) Just place them in holes and glue them with CA glue.
Cups are made out two parts for better printing results without using support on them. Use some sand paper or sharp knife to prepare hole on bottom of cup, since parts have very tight fitting. Use some CA glue to bond bottom of cup and cup together.

Table stand can be used for holding headphones or other stuff ( in near future it will become table light)
On table stand part are on bottom two holes for screws, so stand and table stand holder can be joined together. All you need is to drill 2,5mm holes and tap M3 thread. 2 M3x10mm screws with flat head are needed. Holder fits into Base_big part ( parts can glued together if wanted ).
