3D Printed Jumar

thingiverse

Pretty much a custom-built jumar/ascender designed for 3D printing, which can be adjusted using software like Blender to rearrange pieces for a single print, but works perfectly well with two separate prints. Print Settings Printer: XYZ Davinci 1.0 Rafts: No Supports: No Resolution: 0.4 mm Infill: 10% Notes: This device can be printed in two separate parts or assembled in one go with minimal edits. Post-Printing Assembly Print Size all the holes according to your preferred rod diameter, I used 1.75mm filament for this project. Acetone weld three C-shaped pieces together on top of each other, positioning the L-shaped piece in the corner without holes in the middle of the larger ones and ensuring accurate alignment of the holes. Glue a small 4mm thick line-shaped piece into the gap between the two C's at the top. Attach the wider L-shaped piece to the flat piece from the internal group with two holes each, making sure the holes are lined up precisely. Connect the rod through the holes in the C's to the rounded rectangles. Use the rod to connect the two rounded rectangles to the piece created in step 5, sanding it for a smooth fit. Glue the long 12mm tall piece to one edge of the 100mm by 50mm rectangle using solvent welding. Attach the two C's to the opposite long edge on the same side of the large rectangle, being cautious not to glue the piece from step 7. Position the other 100mm by 50mm rectangle on top of the assembled device and sand as needed for a smooth fit inside. Sand and smooth all surfaces. (Optional) Drill a tiny hole in either the upper or lower rounded rectangle from step 6 and insert a nail into the hole without glue.
