Mamiya CS to Canon EOS Adapter
slackard @Fruts Sorry, a CS to Nikon adapter is not possible. The nikon bayonet is too small for such an adapter... The EOS bayonet is quite a bit larger which makes this adapter possible.
Porsche Mountain Bike "Bike S" Disc Brake Adapter
slackard @blarys Nothing against your bike guy, but fwiw... Typically bike frames are 6061-T6 or 7075-T6. That "T6" value is the type of heat treatment, which ultimately gives aluminum its strength. Heat treating is a sensitive process best left to professionals. Welding to aluminum WILL disturb the heat treat, and will likely weaken your frame significantly, leading to cracks and failure, not to mention scorching your paint job. I guess you could pay to re-heat treat, but that would ruin the entire paint job and you'd be stuck with those additional heat treat and refinishing expenses......Not trying to be all preachy, but welding to heat treated aluminum is not likely to produce good results---go with the 3d printed adapter... & good luck!
slackard @blarys Ok, sounds like you've got the same model as the bike pictured here. "Porsche Bike S"...... So, this adapter will almost certainly work. If your frame size is vastly different than the bike pictured, the design may need a minor revisit, just in case the welds aren't exactly in the same place...... I've sold a few of these without any fitment issues, so you're probably fine buying this adapter. For a guaranteed fit, you can buy the Plastic version first, to verify fitment on your frame. You can also follow this guide: Shoot some photos and send them to me a PM on this forum. With good photos I can make a solid recommendation.....though i will still recommend buying the plastic version first to ensure good fitment..... Good Luck!
slackard @blarys Are you asking about custom disc brake adapters in general? Or specifically about THIS "Porche" bike? Generally speaking, my custom adapters are designed in accordance to the 50.8mm ISO disc brake standard, and can be used with any size rotor, as long as the frame has room for that rotor.. Some frames have narrow stays and larger rotors may not compatible. The adapter on THIS PAGE was designed specifically for the Porche bike pictured above, and according to bike's owner, he could only fit a 140mm rotor on THIS frame -- anything larger was contacting his chain stay.
Disc Brake Adapter for Fisher Level Betty & Joshua
slackard @floridaoccifer I already responded via PM. Here it is again: No adapters for your bike as of yet. I googled around and from the looks of it your Klein may not be a good candidate for a 3d printed brake adapter since the dropout isn't flat and there is no space for mounting bolts... Without a 3D laser scan of your dropout, i couldnt be of much help. However, if you have the old 22mm disc mount on your frame, there might be hope.. check this link for another guy's home-brew mantra adapter. ntra-242234.html good luck

Schwinn S20 Disc Adapter
slackard The source 3d model is identical for plastic or stainless. No scaling is done on my end. Shapeways lists different tolerances for steel and plastic so there could be minute differences, but largely the printed parts will be identical in scale. I always advise customers that if the plastic version fits, the stainless steel version will fit with 99% certainty. For good measure, I also tell people it's possible some drilling or grinding could be required on the stainless version, even though most customers have reported that fitment was perfect right out of the box.
