Walther PDP Compact Magwell-Compatible Baseplates

Why Walther doesn't make a polymer baseplate that fits into their magwells is truly beyond me. Their engineers likely could have modeled this in 1/4 of the time it took me and they already have injection mold tooling, but leave it to the Germans to let me down.

Rather than wait on the Germans, I took matters into my own hands and made these. Included are the STLs and STEP files for both a 15rd +0 basepad for 15rd compact mags and an 18rd over-insertion stop basepad for 18rd fullsize mags. Both are compatible with the aluminum magwell included with the PDP Pro Compact.

The 15rd basepad might work on 18rd mags for a magwell-toting fullsize, but I don't have
one to test with, so let me know if you try it.

I recommend these print settings for best results in terms of print strength
0.45mm extrusion width
4 walls
0.16 layer height
50% infill
Printing with a brim is recommended unless you have bedmesh dialed in
Use support on build plate only if you're unsure of your printer's bridging ability
PLA+ or Nylon is recommended for material as it's the most forgiving when it comes to impacts

It is important that you print these at the angle seen in the included PrintOrientation
photo. We want to distribute all the stress almost perpendicular the layer lines to avoid the spring pressure sheering the lips that keep it attached to the magazine body. This angle also allows for minimal to no supports when printing depending on your printer's
ability to bridge.

I've included the STEP files in case anyone wants to try their hands at modifying these to support Canik 20rd mags(this should only involve extending the top lip of the 18rd basepad some number of millimeters) and PPQ M2 17rd mags(these honestly might work just fine with the 18rd basepad). 

Happy printing! Let me know if you have any feedback. 


Edit) After dropping several magazines on concrete at an IDPA match, I noticed that the lip retention is perhaps a little too thin to hold up to repeated concrete related abuse. I've since gone back and added as much additional material to that area, which seems to have helped alleviate the problem. The models have been updated, so I recommend you redownload them. 

If you have a 0.3mm nozzle, I'd recommend using it for this print so that you get even more walls in some of the thinner areas by using a extrusion width of ~0.33.
