In accordance with the current situation with Covid-19 and as a lot of makers I have start the print of face shields.
But, with the model of headband for A4 sheets that I have chosen (ref https://www.thingiverse.com/thing:4239203), which is 4 holes, no supports, easy and fast to print(less than 3h for a stack of 15 shields in 0,8mm nozzle and 0,35mm thickness and 100mm/sec speed)
) I have been faced to some issue regarding the size of the Rubberband that was not easy to adapt to different head size.
So the following straps has been designed to answer to this difficulty.
The first solution is a multi-hole strap made in filaflex material from Recreus (ref. https://recreus.com/en/20-filaments) that is elastic and that, due to the design can ease the adjustment of the shield when you put one of each from each side. (50mm, 100mm, 150mm and 200mm length are available to fit with most of requirements)
Second solution is a simple clip, printable in PLA or PETG, that is very fast to print and easy to use with an elastic cord by following method.
- Pass the cord in the center hole and make a node
- Pass the node in the slot to hook the cod
- Take the other extremity and pass the rod in the hole and make a node
- Then pass the node in the slot to hook the cod
- You can now pass the extremities of the clip in the extremities of the headband
- To adjust the size just pull on one(or both) of the node
Installation guide for face shield could be found at the following links:
You can also use the objects to strap together a lot of other thinks, this is the reason why a hook has also been design to assemble two (or more) flexible straps.
I hope that it could help you.
