BowFlex SelectTech 840 Kettlebell Replacement Plunger & Mount

prusaprinters

Plunger's foot was somewhere around 1mm too tall creating a slight rocking motion once assembled and kettlebell is sitting on the base. Designed this for a co-worker and for now the rocking isn't bothering them enough to have me fix it. The uploaded design has the plunger's foot shrank by 0.75mm but since the coworker is happy with it for now I haven't printed the updated plunger. Mount fits snugly into the hex holes so I had to very gently tap it flush with a small hammer. The thin "slits" are for a flat screw driver in case the mount needs removed/replaced/whatever. Learned that the hard way in the first revision. Print Settings Printer Brand: Creality Printer: Ender 3 Pro Rafts: No Supports: Yes Resolution: 0.2 Infill: 90% Notes: Printed in PLA @ 0.2 layer height, 3 walls and 90% Gyroid infill. 90% infill because this is on the bottom of a 40LB/18KG kettlebell with about 3mm of vertical space to work in. Mount doesn't require supports but the Plunger does for the thin retention ring to print correctly. Took around 1h in total to print both pieces. Category: Other
