Print-In-Place Rosary Gen 2 (Crusader Version)

This is a print-in-place chain-style Rosary with 100% articulation between beads.  It does NOT require flexible filament- the Rosary shown in the photos was printed in PETG.  I am including the .step file so that artistic folks can redesign and decorate as desired.

Updates for the "Gen 2" version:

• Reformatted to fit on print beds as small as the Core One (250 x 220) WITHOUT scaling, while still being as large as the Gen 1 rosary. [Note: if you have a printer that is much smaller, like an Ender 3, I recommend editing your firmware to utilize the full 235 x 235 build plate, but even then, you will still have to scale the Rosary to 96%.]

• The Our Father beads are now "jewel cut" to help differentiate them from the Hail Mary beads.

• There are some (very slight) internal geometry tweaks to the beads.

• The Gen 2 Rosary comes in four pre-made themes plus one "DIY" version that allows the user to mix and match cross and medallion styles.

Printing notes:

• The STL should open in the slicer in the correct orientation. Do not flip it over!

• Designed for .4mm nozzle (.45mm extrusion width)

• 3 walls, 15% infill

• Use arachne wall generator

• Designed for .2mm layer height (.1 might work, but I haven't tried it)

• NO supports

• If you need to scale the Rosary for a smaller print bed, scale the X and Y axis evenly, but leave Z at 100%.

• You can print this Rosary in a single color, but it has multiple bodies built-in for the purpose of multi-color printing.  Use the paint tool in your slicer or "Split -> To Parts" to reveal the separate bodies to assign different filaments.

Note: In order for this to print right, you MUST be able to print clean bridges.  If you struggle with this, try setting your bridging speed to a very low number (I typically use 20mm/s) and use the below settings:

• “Thick bridges” OFF

• “Bridge flow” set to 1.2

• Bridge fan speed to 100% (if printing with PLA or PETG/PCTG)

You will want to print with a filament that has good layer adhesion, like PLA or PETG/PCTG.  I have not had success printing these in ASA/ABS.

LAST 2 IMPORTANT NOTES:

1. The Rosary is surprisingly durable when printed correctly, but it requires careful removal from the print bed.  I typically "pluck" the beads one at a time until all are free.  Trying to flex your bed for removal puts tremendous stress on the links and can break them.

2. Each link needs to be "cracked" loose once the rosary is off the print bed to allow the Rosary to articulate.  This is by design.  The GIF in the photos shows my method.

Blessed Mother, pray for us!
