Ball-jointed pressure foot (and optional ball...) for a Paulchen branded bumper mount cargo carrier for the For-two Smart. Print Settings Printer Brand: Monoprice Printer: Mini Delta Rafts: No Supports: Yes Resolution: 0.2 Infill: 40% Filament: Inland PETG Blue Notes: You will want to do this in PETG or ABS if you can. It will print with the requisite strength, etc. with PLA- but there's some question as to shock resistance there that leaves some question as to it's long-term suitability for the parts in question. As indicated above, rafts aren't needed. If you're printing the foot, it doesn't need supports. The ball, on the other hand, because of the lip you need to stop the ball from going any further than the end of the pipes that they attach to, you will need supports generated in your respective slicer program. Post-Printing Additional work... You'll want to use something like sticky-backed EVA craft foam and glue a pad for protection of your paint like the rubber ring on the stock foot. Closeup of the completed foot. The foam job doesn't have to be perfect, just cover the flat bottom of your print fully. How I Designed This Introduction and details... Own a AG Daimler Smart car and you'll be amazed at what all you can safely fit in the thing- and yet, you'll end up needing to add a bit more at times. This is where a bike rack/modular cargo carrier that mounts to the rear bumper comes in. One of the best of these is Paulchen's carrier- 88 pounds on the back bumper, no waiting, along with the ability to add bike mounts, etc to the system. Most of the designs, while they're intended to be semi-permanent mountings, most of them are easily removed...but some of the parts can get off the carrier and get lost. The pressure feet in the case of the Paulchen design are such parts. $60 US for a pair of the feet to replace the ball and foot...which doesn't include shipping at the time I asked. I'm not spending that much for a pair of parts that cost Paulchen all of $6 for the both to have made for them. 3D printing to the rescue! The design was a quick CSG job in Tinkercad. It's basically a 7mm high, 35mm wide cylinder with a 20mm ball CSG welded 4mm into the disc. This then has a 16.2 mm sphere as a hole cut into the center of the 20 mm ball's orignal geometry, followed by a 4mm deep cut in the top and a chamfer of about 3 mm into the resulting hole. Finally, 2mm notches are cut into the sphere to cut the ball into quadrants and let it flex. The optional ball is a similar simple construct, of a 16mm ball CSG welded, 3mm into the surface of a stack of cylinders. The minimum for this build you need is the foot. The ball is optional and was added after I got the design built with the off chance you lost the whole foot assembly, Closeup of the pressure foot...
