thingiverse

23.07.2018 Update: After more than six months, one of the rubber bands snapped, I replaced it and now everything is good to go for another six months. 21.04.2018 Update: Three months have passed, and the Rubber band is still holding strong. 10.02.2018 Update: After a month, the rubber-band remains in perfect condition, showing no signs of wear. It's just like it was one month ago, so everything with the rubber band is okay. 12.01.2018 Update: Version 2 is ready; here's the link to check it out: https://www.thingiverse.com/thing:2754426. Let me know what you think - which version do you prefer, V1 or V2? ------------------------------------------------------------------------- I made this holder for insulation of heated beds. With this design, the heated bed remains adjustable. I'm not sure how long a rubber band can withstand the heat of the bed. If it breaks in less than three months, I'll try to make a second version that solves the problem. I'll keep you updated on any changes. You will also need: two elastic bands. I don't know how to use OpenScad, so I chose to make this customizable in Onshape under the following link: https://cad.onshape.com/documents/e0cbc82555ef8bc4a18deada/w/9c1b01fcf8745db05d4bb013/e/9905fb48433535fe11a1c53c. You can customize it with these values: (The uploaded STL has the default values) PCB Heated Bed width (only square) 100-400 mm (default = 215 mm) Cork/Insulation plate width (only square) 80-380 mm (default = 180mm) Cork/Insulation height: 1.5-20 mm (default = 5 mm) Distance from PCB Edge to hole 2-5mm (default = 3mm) Hole Diameter 2-5 mm (default = 3.1 mm) Spring Diameter 4.2-10.2 mm (also fits a washer) (default = 7.2mm)
