Round Folding Plastic Bag Trash Can Holder

Before slicing and printing, it's best to check on your computer if the material's flush volume is 800 Upon verification, if you are not using a P2S printer or have switched printers, the flush volume will be reset to default parameters, which will make the structure difficult to separate and prone to breaking in the middle!!!!!!!!!!!!

2025.11.7 Update: Optimized support structure, reduced filament changes and material consumption, now only requires 1 filament change (when slicing STL files, there will be meaningless supports causing 2 filament changes, I don't want to deal with it, so please use STEP files) Increased material flush volume to reduce adhesion; Optimized the support surface for easy separation after full cooling (I'm not sure if it's easy to separate before cooling because I was sleeping when it finished printing) A GIF image has been added to demonstrate the separation method; Modified the uploaded original model files and some descriptions And I would like to thank you all for your support

2026.4.28 Update: Because some users recently reported a high failure rate, and checking the model revealed an increased number of filament changes, it is speculated that Bambu Lab's slicing algorithm has been adjusted I have re-adjusted the print profiles, and only two print profiles are now retained

When I buy a lot of groceries from the supermarket, I always end up with a pile of plastic bags I usually use these plastic bags for food waste, but some plastic bags are too small and not suitable for regular-sized trash cans

For this, I designed this foldable trash can holder, which can be Print in Place, with approximate dimensions of 14cm diameter x 23cm height

There's a small issue I added some supports in certain parts of the model to reduce filament changes, but after printing, they need to be removed manually You can use diagonal cutters or a small knife to cut off these supports

I used PETG_HF material and PLA_Lite, with a Bambu Lab P2SC printer The parameters used were the official recommended PLA and PETG mutual support settings A little trick is needed to separate the two layers of the stand after printing And I found that due to switching materials midway, the layer adhesion of PETG in some areas was low, making it prone to cracking after printing So I thought using PLA for the main body and PETG for supports might work better(It has been verified that insufficient material flush volume led to low layer adhesion in some areas, the flush volume has now been increased and the number of filament changes for support material has been reduced to 1 It has been verified with PLA supporting PETG, the separation effect is very good, and the material adhesion in other areas is also fine)

The configuration I uploaded is based on the official recommended print parameters for PETG supporting PLA, excluding P2S If you are using other support methods, please pay attention when downloading and importing my model My STEP model seems to have some issues, it will prompt the following problems Just click the prompted repair operation before slicing When slicing STL files, there will be some meaningless supports, resulting in multiple filament changes I guess it's an algorithm issue with Bambu Lab's slicing software
