The Best Scriber - SAE Model with 1/4-20 Bolt and Nut

This innovative design was heavily inspired by The “Fat Boy” scriber made and sold by Philip Sewell from “Tooley Park Furniture”. You can purchase one of his scribers on his website here. I would like to thank Philip for graciously giving me permission to post my model here based on his product.  This model was designed by me in Onshape and can be copied or modified to suit your needs. Here is the link to the Onshape.com model - Scribing Tool. I have posted the STEP files here as well

Happy Making!

P.S. I plan on Making a Metric version of this model, but I do not have the hardware in hand and hesitate to design one and posting without printing one myself. You can always modify my model to make a metric one if you desire.  

Usage:  Set the pencil at the appropriate height and follow the contour on the object you are scribing. 

Printing Tips:

• Body - base on print bed - In my .3mf files I have set variable layer height to print faster but giv the rounded top a nicer finish.
• Wheel - Set on print bed with nut slot facing up
• Knob - Flat side down
• Wingnut - Flat side down,  with bolt hex facing up

Filament - PLA ot PETG suggested

Infill - 20% for is fine

Layer Height - .2mm- for the smaller parts and .25-.30mm for the larger parts

Supports - None

Parimeters - 2-3 are fine

Additional Parts - 1 - (2" or 1 ¾") ¼-20 bolt and 1 - ¼-20 Nut

Bed Adhesion - Up to you but a little glue stick is a good insurance policy. 

Rafts - None

Scaling - Not recommended 

Filament Change - None

Post Printing Notes:  If you have a ¼-20 tap, it might be a good idea to use it on the threads in the Wheel for the Knurled Knob. If you don't have a tap, then run the bolt in and out a few times to wear it in a bit. Also do the same with the Knob in the bolt. But take it slow and easy with the knob as excess pressure can break it. 

Happy Printing!
