Cover for Animation Disk Acme Peg Bar

thingiverse

This thing was requested by my daughter for her animation disk (Desk available from Colin Johnson @ www.animationdesks.com) to provide paper/pen support when she just wants to draw (without using the registration pegs on the animation bar). I measured the dimensions of and between the pegs and just used Sketchup to draw it up. Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.3mm - Course in MatterControl 1.4 Infill: 10% - strength not an issue and helps conserve on filament Notes: used Yellow Hatchbox 1.75mm PLA Filament. PLA probably best to avoid ABS shrinkage around pins. Both STL and Sketchup files provided. No Support needed if printed with lip up. Post-Printing Your Mileage May Vary... The hole for the central cylindrical pin was a tad bit too tight. I was looking for a tight fit, but don't want to damage the Acme pins as the Thing goes on & off - so it should be an easy fit. I ran the shank of a drillbit (shank measured 0.245" diameter) through the central hole to burnish it out a bit and mine fits perfect. The Acme Registration pins are a standard animation setup, but I do not know how well this Thing will match a different Acme Animation bar, so YMMV. I would suggest printing out the first few layers and doing a test fit, before printing the whole Thing. How I Designed This Reverse Engineer and Sketchup I measured the dimensions of and between the registration pegs of the Acme Animation bar provided by Colin Johnson in the Animation Disks of his Animation Desks. I then used those dimensions to draw a simple rectangular solid in Sketchup. Exported as STL. I added a small lip where the Thing touches the Animation Disk so that it sits flat against the surface of the disk.
