**********
This is a collar installed onto the glass cylinder and guards it from breakage if the cylinder is knocked over. It comes in 5 sizes.
NOTE: These collars are inspired by the Eisco brand collars, but has some other enhancements, customized for 3D printing.
Features:
- Comes in sizes: 50ml, 100ml, 250ml, 500ml, 1000ml
- STEP files attached for you to modify for your needs.
- Scaling directions provided below.
The collars are sized for the following diameters:
| Size | Outer Diameter, mm | Collar Inside Diameter, mm |
|---|---|---|
| 50ml | 25.8 | 26 |
| 100ml | 30.8 | 31 |
| 250ml | 42.8 | 43 |
| 500ml | 54.8 | 55 |
| 1000ml | 61.8 | 62 |
Depending on the brand of graduated cylinders you use, your cylinder diameter may vary up or down, so just scale the X-Y dimensions accordingly before you print.
Example: If your 1000ml cylinder is 63.2mm in diameter:
- Use 63.2/61.8 = 1.023
- Change the X and Y scale on your slicer to 102.3%, while keeping your Z scale at 100%.
- Print 1 piece to test fit first, then print more as needed.
Printing Recommendations:
- Use PETG or ABS. These materials are tougher to withstand impact forces of a cylinder falling.
- Print using 2 vertical perimeters (up to 3 perimeters for 500ml or 1000ml), no more. You need it to remain a bit flexible so you can flex them during installation.
- If printing in TPU, use ones that are of 95A durometer, and be careful you have the extrusion multiplier dialed in, so some experimentation may be needed.
Installation:
- Align the collar opening to the pour spout.
- Pull open the collar to fit over the spout and top lip.
- Slide collar down to just above the graduated markings.
- Rotate the collar about ¼ - ½ turn.
