Kệ úp dụng cụ lab dạng đứng đơn giản (Simple Standing Lab Drying Rack)

This model was created for the MSF collaboration challenge hosted by Printables. It is a simple drying rack for labs, with configurability and options for dovetail-based modularity. It was inspired by my mom, who works in biology.

Attached is stls for the various configurations with a peg size of 6mm, and an Onshape link, which can be used to configure and then export it in any file format.
 

An offset of 0.3mm is applied to all meshing surfaces for tolerances. I have found this to work for me, I decided to not add a configuration for tolerances, but you are free to copy the Onshape doc and make your own.

Configurations
There are 4 main variables to configure:
- Peg type: You can either have the model printed with pegs, or with holes that can fit wood or plastic dowels
- Stand dovetails: choose whether the standing supports for the model are attached with a single piece or are dovetailed on. Primarily so that you can choose to print it flat
- Conjoiner Dovetails: Choose whether to add dovetails on the side to chain multiple units together (this is what the stl names mean by “modular”)
- Peg size: Diameter of the pegs, limited between 1mm and 15.5mm, as any larger and it would break the cad.
 

Print Settings
- Supports are likely needed, as there are dovetails

- High walls (4 or higher) and minimal infill (10% or whatever you've found works for your printer/filament) is suggested. You may also want to print the pegs/dowel holding areas entirely solid.

- Need a strongish filament, PLA+ is fine. Depending on the chemicals/biological substances in the glassware, you may want to print with more resistant filaments such as Nylon, PP, or PETG
