Fitbit Charge HR Strap Grip Replacement

thingiverse

FIRST VERSION: The original strap has a retainer that engages the excess end of the strap from the outside of the strap. With this replacement the retainer engages the leftover of the belt with two pivots —instead of one— from the inside of the belt. The piece is slightly curved and the pivots point diverging from each other, so it is necessary to use support. The edges that are in contact with the skin have been chamfered but surely not enough value (it seems necessary to soften them a bit more). Requires removing the buckle for assembly. To cover a little the pivots I have painted them with permanent black marker, although I recognize that totally blank also looked well. The measurements are very fair to pass the belt, probably in a following version I will provide a little more margin. SECOND VERSION: A thinner model with only one pivot, as the original one. I'm testing it. The first version was delicate and the pivots were broken easily. Now the strap can be printed horizontally, with less support. Print Settings Printer: Anet A8 Rafts: Doesn't Matter Supports: Yes Resolution: 0.1 Infill: 100% Notes: The piece is slightly curved, so you have to print it standing up and you need to use support. White plastic PLA has been used. Post-Printing Soften edges in contact with the skin You probably will need to soften the edges that are in contact with the skin in this first version. The black part has been painted with a permanent marker. How I Designed This Basic Design Designed with Scketchup and processed with Cura. Printing time was 30 minutes.
